Why is it important to understand the difference between gauge and absolute pressure?

Pumps and similar systems are built in a way so as to generate and retain pressure. In gas-based systems such as air compressors, the pressure is fairly low. This is because gasses when compressed incessantly makes air molecules huddle nearer to each other in the application of energy. This pressure doesn’t extend to the tubes or chambers of the compressed air systems.

In brief, pressure can be defined as a force acting over a certain area. It’s most commonly measured in pounds per square inch (psi).

There are multiple systems to measure pressure. Two of the most common ones are absolute and gauge pressure. There are quite a few differences between the two that have considerable impact on their use and measurement. Once the purpose behind measuring pressure is identified, the next step involves choosing which system to use: gauge or absolute pressure. This is a crucial decision since choosing the wrong system can severely impact the accuracy of measurements.

The pressure inside a compressed air system is comparatively lower. Hence, even minor deviations such as 10 psi or 20 psi can lead to major operational issues.

Here are the differences between the two systems in great detail:

Gauge Pressure

It’s one of the most commonly used systems of measurement and uses atmospheric pressure as its base value. So, any chamber will equalize based on the atmospheric pressure, when vented. This makes it easy for calculations and tests since the atmospheric pressure doesn’t have to be subtracted.

Also known as effective pressure, gauge pressure is signified by BARG or BARE and PSIG or PSIE.

Absolute Pressure

Comparatively, absolute pressure is used less frequently, since it signifies zero pressure or a perfect vacuum. A good example of the measurement of absolute pressure can be that of barometric pressure.

Absolute pressure is commonly signified by BARA and PSIA.

Choosing the right system: gauge or absolute pressure

The most fundamental difference between gauge and absolute pressure is that gauge pressure uses atmospheric pressure as its base or zero point whereas absolute pressure uses absolute zero as its base or zero point.

So, if the idea is to measure a type of pressure influenced by atmospheric pressure, it’s best to use a gauge pressure. It will help measure the pressure minus the atmospheric pressure. This is the system used to measure the output of pressure of air compressors.

Again, if the idea is to measure a type of pressure not influenced by atmospheric pressure, absolute pressure is used as a reference. An example of this can be leak testing a sealed container.

SP Coupled Pumpset With IE5 Motor — The Ultra Premium Efficiency Pump

Kinetic pumps propel large volumes of fluid at low pressure, while positive displacement pumps move relatively small volumes of fluid at high pressure. Before further pressure or velocity can be increased, a certain level of pressure is necessary to get the fluid to flow into the pump. Cavitation (the creation of a void space in the pump that is typically filled with liquid) will take place if the inlet pressure is too low. Cavitation is frequently caused by the vaporization of liquid in the suction line. A greater pressure zone causes the vapor bubbles that were brought into the pump with the liquid to collapse, which causes excessive noise, vibration, corrosion, and erosion. The necessary inlet pressure, the capacity against a specified total head (energy per pound owing to pressure, velocity, or elevation), and the % efficiency for pumping a certain fluid are crucial features of a pump.

Don’t Get Flooded Out — Opt For The Original Kirloskar Dewatering Pumps This Rainy Season

What are dewatering pumps?

A dewatering centrifugal pump is typically used to remove water from one site and move it to another. A dewatering pump has a variety of applications in the construction, mining, mill, and municipal industries. A dewatering pump is useful for use in any area that needs to be maintained dry and clean, such as roadways and construction sites. A dewatering pump’s efficient flood control, inland wastewater management, and fast drainage features make it especially useful during the monsoon season. In reality, a dewatering centrifugal pump performs the same tasks as any other pump. The dewatering pump uses an impeller with a blade to initiate and maintain the flow of water, just like a centrifugal pump does. The fluid enters the impeller eye, a tiny area of the impeller. The water flow is then gathered from this location and directed to the diffuser, which is a discharge nozzle with a cone-shaped shape. This is the point where the water’s velocity is lowered and the energy of the flow of the water is converted to pressure energy.

For maximum effectiveness, the water is then evacuated from the pump following the aforementioned procedure at an angle of 7 to 10 degrees.This is the dewatering stage. Electric motors are typically employed to speed up this procedure. Some pumps, though, might employ various motor types. A sturdy and compact design, light weight for transportation, high fluid capacity, and high abrasion resistance are special properties of a dewatering pump that enable the most effective handling of muddy water and slurry.

Why should you go for Kirloskar dewatering pumps?

Is Your Construction Site Safe? Do You Have A Proper Dewatering Solution?

Dewatering of a construction site refers to the process of water removal from pits or excavations to create a dry base where work can take place. If there are trenches filled with water or floods, the site will be unsafe and unsound to operate on. This is why dewatering pumps are used to drain these water-logged areas with a high water table or insufficient slope to make the site a more conducive workplace. 

Dewatering Pump Considerations for Shaft Construction

Another major factor when dewatering a site is to ensure that the water is discharged safely at an appropriate location, preferably into a wetland, lake, or storm sewer. Otherwise, there may be risk of problems like soil erosion and instability.

A Checklist of Precautions to Take When Dewatering

  • Do not pump water directly into slopes
  • Discontinue dewatering if you notice any signs of erosion or instability
  • Ensure that dewatering channels are stable and covered with protective vegetaion or grass if possible
  • Do not dewater when there are heavy rains in progress
  • Do not directly discharge water that has been contaminated with chemicals or grease without separating them

Dewatering Pumps for your construction site

So how can you select the correct dewatering pump for your needs? Let’s take a look at different types of dewatering pumps and their benefits to get a better idea.

Self Priming pumps

As the name suggests, a self-priming pump has a special built-in mechanism that enables it to prime itself without manual intervention. They also come with a flood-control feature for quick dewatering and wastewater management. They can be used for frequent pumping operations and use less power and time to run than other centrifugal pumps. They are safe to operate and are the perfect choice for the monsoon.

Eterna CW/BW series

The Eterna CW/BW series of sewage dewatering submersible pumps are another great option. They can remove stagnant water from the basement, underground parking, and garages. These pumps drain accumulated stormwater during the monsoons, empty water tanks and pits, and remove wastewater from kitchens, hotels, clubs, and surplus water from sumps.

Auto prime pumps

An auto prime pump can provide a safe, efficient, and cost-effective solution for pumping larger liquid volumes. It is portable, simple to use, sturdy, and ideal for pumping water when suction is difficult. It can also be used to pump a variety of liquids (of different viscosities) apart from water, such as slurry. Auto prime pumps are useful in a vast variety of ways such as in groundwater control, sewage over-pumping, wellpoint dewatering, flood relief, mine dewatering, pipe relining, industrial sludge pumping, marine ballasting, tank sediment clearing, and emergency dewatering services.

Cutter pumps

Cutter pumps are designed to process heavy industrial waste and raw sewage material and to classify general wastewater types. The way they have been built eliminates any chances of clogging that is usually caused by oversized particles and objects like plastic bottles, aluminum cans, ropes, cables, fabrics, and all flushable products.

Cutter pumps can be used to drain sewage and wastewater from buildings and kitchens, and to move sewage and wastewater between water treatment facilities of factories and commercial sites.

At VEMC, we provide all the above types of dewatering pumps, so you can take your pick from any series that suits your requirements best for the monsoon season.

Preventing Water from Affecting Your Site

If you know that the soil in the area is less permeable than usual, you can try to cut down on the dewatering process by separating the layer of soil that is low in permeability from other sources of water. Slurry walls, sheet piles and grout curtians may prove useful alternatives to keep out water from coming into the construction base. Although doing this will probably not eliminate the problem completely, it comes in handy when the water table is high. You may still have to dewater the area to remove residual rainfall, but it is advisable to conduct a comprehensive engineering analysis to determine how this process will affect the other areas.

Methods, Tips & Precautions for Construction Dewatering

Dewatering is the removal of water, where it is drained out by pumping from a particular location. Basically, dewatering provides a dry foundation to work on by reducing the ground water table of the site. Whether you are constructing, running sand, or repairing sewers, dams, buildings, tunnels, or a basement, dewatering can prove very useful.

Choosing the right method for your project is very important. There are four main methods of dewatering — the well point method, eductor wells, open slump pumping, and deep well point method. Let’s take a look at them.

Well Point Method

In the well point method, the groundwater is channelled by the pump through the header pipe before getting discharged. This is a fairly, flexible and cost effective method under a wide variety of soil conditions.

Educator Well

This dewatering method is a lot like the well point system, but instead of a vacuum, high-pressure water is used to draw water into the well points. This method can be an effective in soils that are less permeable.

Open Slump Pumping

In the open slump pumping method, slumps and drains are constructed at one or more points of the excavated pit. These then collect the groundwater. This is one of the most convenient and cost-efficient methods.

Deep Well Point Method

The deep well point method is appropriate for a deep excavation when a large amount of groundwater needs to be removed.

Precautions to Take in Dewatering

  • Make sure to conduct the process under special supervision and look out for any signs of instability or soil erosion.
  • Do not pump the water directly into slopes.
  • Used a wooded buffer if you can.
  • Choose an appropriate area to discharge the water, ideally a forest buffer zone.
  • Ensure that the channels used for dewatering are stable and covered by vegetation or grass if possible.
  • Avoid dewatering during heavy rains.
  • When removing water that is contaminated with chemicals, grease or oil, do not discharge it directly. Use an oil-water separator before disposal.
  • Make sure you have all the relevant permits and licenses for dewatering before discharging water.
  • Check and verify the state of the water table at the location of dewatering. If it is too close to the surface, the plan may not work.

Watering VS Dewatering Pumps: The Basics

What is a water pump?

Water pumps are mechanical devices used mainly to transfer water from one place to another through a motor converting rotational or kinetic energy into hydrodynamic energy (for fluid flow).

Water pumps usually have three primary parts. These are an inlet, a pump system, and an outlet.

The water gets drawn into the pump from the inlet side when a difference in pressure forms within the pump system. The water is led from an area of high pressure to an area of low pressure, which is then used to move the water to the side of the outlet through the pump, then into a hose, and finally towards the water tank.

What are the uses of a water pump?

Applications of a water pump range from irrigation in agricultural farming systems to water extraction in construction sites. They can also be used in supplying water to residential, commercial, or industrial sites.

What is a dewatering pump?

A dewatering centrifugal pump, just like the name implies, is mainly used to remove water from a particular place and move it to another location.

A dewatering centrifugal pump functions just as any other pump does. It uses an impeller with a blade to begin and continue the movement of the water. The water goes into a smaller part of the impeller called the impeller eye. The flow of the water is then collected from there and directed to the diffuser, which is a conical-shaped discharge nozzle. This is when the velocity of the water is reduced and the energy of the water flow is changed to pressure energy.

After the process described above, the water is then removed from the pump at an angle of 7 to 10 degrees for optimal efficiency. This is the stage of dewatering. To help this process along, mostly an electric motor is used. However, some pumps may use different types of motors.

What are the uses of a dewatering pump?

A dewatering pump finds several applications across various industries including construction, mining, mills, and municipal operations. Any place that needs to be kept dry and clean, such as roads and worksites, will benefit from having a dewatering pump to work smoothly with. During the monsoon season especially, a dewatering pump comes in extremely handy thanks to its effective flood control, groundwater removal, inland wastewater management, and prompt drainage functions.

How Can You Select the Right Dewatering Pump for Your Building?

Industrial sites often have areas that get clogged with excess water and sludge from things like the rain, a high water table, and melting ice. Dewatering is an essential process in such cases. However, it requires adequate planning and preparation. So how can you select the right dewatering pump for your building? Let’s take a look at factors you should consider.

Pump size

It is the size of the dewatering pump that determines how much load it will be able to process. Pump sizes may range from 1 kW to 10 kW for most industrial purposes. Operating the pump at its maximum capacity makes it prone to mechanical issues which may create downtime. So, if the pump needs to be run continuously, it is better to install multiple dewatering pumps at the site. Called parallel pumping, this method helps your equipment to function for longer periods.

Discharge head

You should also consider the total height of the discharge pipe which is known as the discharge head, along with the height from the point that the water is pumped. If you need to pump the water from a significant height, be sure to choose a higher discharge head. As well, the suction head capacity will determine the depth of the water being pumped.

Flow Rate

The flow rate of the pump indicates how much time the pump will take to complete the work fully. Depending on how fast you would need the dewatering process to be finished, select a pump with a flow rate that matches your requirements appropriately. Keep in mind the size of your site and the amount of water that is to be removed. For a quicker rate, pick a pump that can discharge a higher volume of fluid per minute.

Flexibility of location

If the nature of your work demands that the pumps be moved around easily as opposed to fixed to a particular location, it would be best to choose a pump that is portable. Although it may be tempting to select a cheaper model that is not, doing so would take more time and resources to relocate during operation and cause inconvenience.

Availability of electricity

The dewatering pumps will need electricity to function, so it is important to ensure that there is access to sufficient electricity at the site.

Waste removal

The dewatering process can unearth a lot of sludge and other solids from groundwater. This is why it is necessary to select a pump that can withstand and pass these through an efficient built-in waste removal system.

Keeping the above factors in mind will help you make a prudent choice when looking for the best dewatering pump for your building and application.

A Guide To Select The Best Water Pump For Industrial Use In India

We need water for a variety of essential purposes — whether it is to cook, wash, clean, or perform industrial functions. This water comes to us from the source through a pump. When you are buying a water pump, there are a number of factors to consider before identifying the right kind for your application. Before we look at what these different factors are, watch this video to get an idea about how to select a water pump:

https://www.youtube.com/watch?v=9i_c-LBEXkw&ab_channel=VijayEngineeringandMachineryCompany

Flow rate

Given in cubic metres per hour (m3/h) or litres per minute (l/min), the flow rate of the pump measures its efficiency, that is, how much water it can pump out within a certain period of time. For industrial applications, this flow rate should ideally be on the higher side, of at least 2000 litres per minute. Another reason that the flow rate is so important is that it determines the daily energy consumption as well as the durability of the pump. The lower the flow rate, the higher the energy consumed due to more prolonged usage.

Discharge head

The total height of the discharge pipe which is known as the discharge head, as well as the height from where the water is pumped, are further aspects to consider when choosing the water pump. If you need to pump the water from a significant height, make sure that you choose a higher discharge head. Additionally, the suction head capacity will determine the depth of the water being pumped.

Inlet

The size of the inlet facilitates the correct flow of the water. Too small an inlet will create friction and a subsequent loss on the pump system. So, be careful that you choose a good-sized inlet for optimal water flow and pump performance.

Water quality

It is necessary to keep in mind that different water pumps and motors, such as trash pumps and dewatering pumps, are built to work with different kinds of water. Trash pumps transfer dirty water quickly while the latter kind moves clean water between locations. When you choose a water pump for your needs, it must fit the specific purpose you require it for and should not be used inappropriately.

Pump quality

Just as the quality of the water that goes into the pump must be suitable, you must also consider the quality of the pump itself. For the maximum efficiency and compatibility, select a pump from a reputed brand and do not compromise on its quality and design. A good quality pump will last much longer, cost much less to maintain, and will consume less energy in the long run. Kirloskar is a trusted name in the industry and would be a safe bet.

Here’s How You Can Understand Centrifugal Pump And Motor Torque-Speed Curves

A centrifugal pump is powered by a motor that has to produce adequate torque to start off the pump and take it up to the best speed. Without enough torque, the motor might not be able to start the pump at all or only have it function at a lower speed.

To determine the motor that is most appropriate for a pump, we use what is called the pump’s torque-speed curve. We can make this by vertically mapping the percentage of full load torque (FLT) against the percentage of horizontally mapped full load speed (FLS).

The torque-speed curve is common in all centrifugal pumps because though the pump torque changes with its squared speed, when the full load speed (FLS) is at zero percent or at rest, the full load torque (FLT) will never simultaneously be at zero percent. The motor must overcome static friction and inertia in order to start a rotating pump. This brings us to the question of how much full load torque is needed to do this. The answer — about 20% of full load torque. As the speed of the pump increases, the torque that is needed slowly decreases. (At 15% full load speed, about 5 to 10% full load torque is needed.)

Horsepower (HP) is a combination of speed denoted by RPM, and torque. The horsepower of a motor is a basic measure of its abilities. The torque of a motor is calculated with the following formula:

T = (5,250 x HP) / N

(T = Torque, and N = RPM)

When you need to select a new motor for your pump, there are three important values you need to look at. These are:

  • Torque at zero flow
  • Torque at rated flow
  • Torque at maximum flow

Additionally, you will need to consider the inertia value of the pump at the motor shaft. The higher this is, the more time the motor will take to start off the pump and get it to the full load speed. This is important because the longer this is, the more heat is generated. The size of the motor must be suited to handle the inertia of the pump. Otherwise, the motor’s windings may get damaged.

In the case of the motor driving the pump directly, the inertia values of the pump-motor combination and the pump itself will remain constant no matter the speed of the pump. However, if both a gearbox and motor drive the pump, the inertia values will be affected greatly.

To choose the right kind of motor for your centrifugal pump, the above factors are important to keep in mind.

How Can You Mitigate a Mechanical Shaft Seal Leakage?

Why does leakage occur in a centrifugal pump? To understand this, we must first understand how a centrifugal pump basically works. As fluid goes through its impeller eye and up the impeller vanes, it starts with low pressure and velocity. As it flows into the volute and gets ready to exit, both the pressure and velocity increase. As the fluid flows out through the discharge, the pressure is high but the velocity gets reduced. The flow then goes out of the pump, which makes the pump exert pressure and raise the energy of the fluid.

When a component of the pump such as static joints and hydraulic malfunction, the whole system might break down. However, a majority of pump failures happen due to the mechanical seal of the pump malfunctioning.

A mechanical seal controls the leakage between a liquid and a rotating shaft. To do this, essentially all seals have to leak in order to maintain a film of fluid over the whole face of the mechanical seal. The leakage from the atmospheric side is quite less. But the leakage between the mechanical seal shafts and sleeves can cause significant issues. Often, the reason these happen is because of the fretting of the O-ring seal on the shaft. You will notice substances dripping from behind the seal close to the drive collar. Polishing the fretted part can provide a temporary fix, but it will not give you a solution. Here are some options you can choose in the short and long term:

Short term solutions

Replacing the shaft could be a practical option given that the maintenance cost is low and you would not have to overhaul the entire pump system.

When repairing or replacing the shaft is proving to be difficult, you can opt for a modified seal but you may have to plan in advance.

You can try relocating the O-ring of the seal sleeve with the help of a local technician. When you get to the bottom of the issue, you can check where the damage on the shaft is and shift the O-ring accordingly. If you still require a new sleeve, the cost will be only a little bit higher.

Long-term solutions

Upgrade the shaft to a higher quality material.

Consult a pump technician and coat the shaft below the seal sleeve with a substance like tungsten carbide. How much of the shaft you may need to coat will depend on the damage. Avoid the area around the drive collar set screws. Make sure to enlist professional support for this.

Process Pumps: A Must-Have for Handling Industrial Fluids

What is a process pump?

A process pump transports liquids and semi-liquids from one place to another. It is an essential tool for several industrial applications which involve moving water, slurries, mud, chemicals, or oil.

Parts in a process pump

Although there are a few different kinds of process pumps, most of them are made up of the same main components. These include the primary mover which powers the process pump which can be a motor or an engine, a V-belt or direct coupled drive to help slow it down, and a gearbox. 

Types of process pumps by Kirloskar Brothers Limited (KBL):

  • AT

The Kirloskar Air Cooled Thermic Fluid AT series of process pumps come with a back pull-out design. This allows easy removal of the rotating unit of the pump for inspection and repairs without disturbing the suction and delivery pipe connections.

  • ROMAK

Kirloskar’s Romak (RM) process pumps are used for handling various types of chemical liquids and make for leak-free transportation. They are manufactured to close tolerance and are of rigid construction. The Romak pump is a magnetic drive pump.

  • GK(P)

Kirloskar GK(P) pumps are used for handling different types of liquid chemicals. These are also manufactured to close tolerance and with rigid construction. The complete range of GK(P) process pumps is covered by four driving units, thereby reducing inventory and achieving interchangeability.

  • i-CM

Kirloskar i-CM process pumps are mainly used for chemical and process handling applications, which are free from suspended solids particles. i-CM process pumps are ideal for pumping corrosive and noxious fluids.

  • i-CP

Kirloskar i-CP pumps are horizontal, radially split, single-stage, centrifugal end-suction volute with top centerline delivery. The impeller is of an enclosed type. The bearing housing is fitted with a support foot. The pump shaft is supported by pre-lubricated anti-friction sealed bearings as a standard scope of supply. i-CP pumps come without any mechanical seal or gland packing arrangement and yet ensure zero leakage from the stuffing box. This feature is achieved by the innovative design of the shaft sleeve, expeller, and fluid arrester.

How can you choose the right process pump for your purposes?

Some factors you should consider when selecting the size and kind of a process pump are the type of fluid to be moved, its temperature, specific gravity, and viscosity. You also need to take into account your specific pressure and flow requirements for the task, as well as the type, diameter, and length of the piping.

The Role Of Temperature In Pump Selection

When choosing a pump for your industrial or commercial applications, there are several factors that you need to consider. The role of temperature is a major one, how hot or cold the fluid in the system is, the levels of heat generated by the pump and other equipment, and the particular range required for the operation, being key. So why is the role of temperature so integral to the pump selection process? In this blog, we will outline the ways in which temperature can have an effect on your pump and operations. These are as follows:

Corrosion to construction parts

The temperature of the pump can cause corrosion to the parts or construction materials if you plan to be pumping specific kinds of chemicals. Keep in mind that the hotter the liquid, the more corrosive effect it can have. Thus, it is crucial to check the compatibility of different chemicals and the temperature at which you are going to be pumping.

The pump’s components

With an increase in the temperature, heat gets transferred from gland packing to the bearing through the shaft. This takes a toll on the bearing by shortening its life and possibly even seizing it if the pump’s gland is saturated. This must be avoided at all costs for the pump to be function at peak efficiency.

Viscosity of liquids

Fluids that are affected by temperature can see a change in viscosity during the pumping process. For instance, some become runny when heated, thus influencing how they will be pumped. This is why it is important to understand how temperature can change the viscosity of your product in order to select the right pump.

Expansion of parts

Metal parts can expand at varying rates at high temperatures. So it is essential to finalize the materials of construction while you are choosing the pump itself.

Maintaining the temperature

In certain cases, you may need to maintain a specific temperature or a range of temperatures depending on the application. You can achieve this by preserving the conditions of the flow or use a heating jacket which permits you to maintain higher temperatures. Conversely, you can implement proper insulation in the system to maintain a lower temperature.

Even if you have a suction for the pump that is flooded, it is important to note that you will still have to take the vapour pressure of the liquid, as well as the temperature into consideration in order to ensure that your pump contains the right Net Positive Suction Head Available (NPSHa).For more information on industrial pumps, motors, and other equipment, feel free to reach VEMC on +91-9819907445.

Pump Guide: How to Overcome the Biggest Problems with Pump Life

Sudden pump failures can disrupt your business and delay project delivery. The hidden cost of breakdowns, owing to business loss, may exceed the preventive maintenance costs of the pumps. Pumps often face delivery failure, priming failure, excessive vibrations, reduced capacity, overload, and loss of displaced liquid. In this blog, we talk about factors affecting the pump life and ways to overcome their challenges.

  1. The type of liquid being pumped: Your quest to prolong your pump life starts with determining the liquid pumped in it. Factors like temperature, viscosity, suspended particles, acidity, etc., of the liquid, are crucial in determining the pump’s ability to withstand exposure.
  2. Material of the pump body: After testing the nature of the liquid, which maintains constant contact with the body of your pump, consider the material of your pump body. Can the pump material withstand contact with a specific type of liquid?
  3. Role of the pump: What’s the usage of your pump? Anticipating the usage of your pump can help in choosing the right one. Pumps play a critical role in some industries, and it is, thus, unwise to use an average pump. Similarly, find out if your business operations require a standardized pump operation or additional features that are available only in specially designed pumps.
  4. Always ensure pump inlet: You must never allow your pump to starve, which is the leading cause of pump seizures. To determine the inlet pressure, you must regularly take the Net Positive Suction Head (NPSH) reading and ensure the NPSH available (NPSHA) exceeds the NPSH value of your pump.
  5. Pump location: The immediate location and surroundings of the pump operation are crucial. Pumps operated outside need special care with regard to temperature and environment. You may need to protect the pump using special shelters or protection closets if there are apprehensions.
  6. Flow rate and pressure: The flow rate and pressure of the displaced liquid is an important consideration. It determines the size, length, and material of the inlet and outlet pipes. Their capacity must match the pressure requirements of the pump’s functions.

An understanding of these aspects affects the depreciation of your pumps and prolonging their valuable life.
