What makes a fire pump different from other kinds of pumps?

Are you also amongst the ones who don’t find any difference between fire pumps and other pumps, primarily domestic water pumps?  Both pump water, don’t they? But they are as different as the scenarios they are employed in. And as the material and construction of fire pumps is different, they are far more costly than ordinary pumps.

So, before you go switching your fire pumps with domestic water pumps to control the cost, let’s take a look at the differences between the two:

  1. Corrosion-resistant- As we mentioned, both pumps are used in different situations wherein the fire pump is an emergency pump, rarely used in normal times. But all the time it is not in use, the fire pump still needs to be intact for whenever it is needed. So, a fire pump is constructed, keeping in mind to keep its corrosion resistance factor high- much more than that of an ordinary water pump. Like, water pumps have a cast iron material used in the construction of their impeller, compared to the pure copper or stainless steel impeller of fire pumps.  
  2. Fire pumps have to be fire-resistant- No matter how similar their applications might look, it is important for a fire pump to be fire resistant- something a water pump doesn’t need. A fire pump is not merely supplying water, it is used douse fires so, the material of the pump has to be metal and the surface of fire pump needs to a red paint coating, which not only stops it from getting rust but also fire-proofs it.
  3. High-temperature resistance- Fire pumps have to be high-temperature resistant as they may have to counter scorching heat in the event of a fire hazard, something ordinary pumps don’t have.

Factors to Consider When Choosing Gate Valves

Gate is one of the most used valves when opening and closing the flow of liquid from a straight medium line. The gate valves are usually found in different places. Instantly they are found in the irrigation areas and can be used in different plantation areas in regulating various fluids.

Valves are essential components used in the pumping systems in diverse industries. Some of the main functions of the valves is preventing backflows, regulating the direction of flow as well as regulating the system pressure, the UL /FM approved gate valves may sometimes be dismissed as secondary considerations while designing different faucets at your home. This is necessary because they increase the performance of the systems minding their efficiency, longevity, and safety. This article, therefore, will discuss the critical factors you should ‘put into consideration while selecting the gate valves.

The type of valve used:

The water faucets at home are mostly made of valves with handles used in regulating the flow in it. The valve, therefore, should be designed with a gate as well as an actuator. The actuator is usually made of level, electric motor or a handwheel. Each of these creates the anticipation of regulating the performance that makes the valve useful in given conditions. Therefore, the gate valve is regarded as a piece of metal that determines the passing and non-passing of the flow.

Actuation Method

It is necessary to consider the operation of the valve. Therefore you need to determine if the valve is manually operated by hand or it will require an actuator for turning it on and off automatically. If you settle on the latter, then you decided on the unit that will be used if it will require, pneumatic, or hydraulic actuator. There are other several Gate Valves Ul/Fm Approved and used in different industries with electric motors. Therefore, it is necessary to determine the functionality of the gate valve.

Maintenance Requirements

Maintenance should be done regularly; the gate valve requires maintenance to ensure they do not clog. Hence, this is the simplest method of providing the gate valves to serve you for a long time. The gate valves are designed in a way that makes them easy to clean without having to disconnect the end cups from the pipe. This, therefore, prevents the line from shutting done during the maintenance process. The most common uses valve the wedge valves that are parallel, the valves are utilized highly because they easily overcome the contraction and expansions in the climate that fluctuates regularly.

Application Conditions

Selecting the right gate valve for application in the essential factor when choosing a correct valve for your application purpose. When the valve is not appropriately sized, it may lead to operational issues within the valve or in the system. This also determines the temperature, flow rate and pressure that the valve operates with. However, metal valves in most sentences withstand the high temperatures as well as the pressures as compared to the plastic ones.

Valve Function

Before installing the valve gate, always consider determining the need of the valve. They are typically used in on and off controls, diverting as well as media mixing. Also, consider if your valve will be open or closed. When you want to increase the life expectancy, you should consider the order value in the orientation as well as the changes on different valves.

Finally, there are diverse factors involves when selecting the right UL /FM approved gate valves for your application. It is essential to seek the help of qualified engineers to help in analyzing the critical factors as well as in understanding the application requirements. This will; be essential in finding the right gate valve for your application.

Various reasons for a centrifugal pump not discharging water

When centrifugal pumps produce inadequate flow, not only is the pump’s efficiency compromised, but the entire system suffers a gradual breakdown until the problem is solved. But often, we put the entire blame of the low flow on the pump itself, misdiagnosing problems in the system as pump problems only but to solve issues related to the performance of the system one has to look at the bigger picture.

Reasons for a centrifugal pump to produce a low flow of water

  1. A clogged suction pipe: If a suction pipe is riddled with debris, there is less flow into the pump, which in turn leads to less flow out of the pump.
  2. Worn impeller, ring, and plate: If the vanes on the impeller, the ring, and plate have worn down, the hydraulic capacity of the pump is hampered.
  3. Reversed Impeller Rotation: Often, a pump’s motor is bump started without first ensuring whether the pump is hooked up for proper rotation of the shaft. So, when the motor turns in the wrong direction, the shaft is pushed back by the impellor which nat damage the internal surface of the pump.
  4. Excessive Clearances: Excessive slip may occur if the clearances are too wide for the type of fluid pumped causing the fluid to recirculate inside the pump, thus causing the lower flow.
  5. Debris in the impeller: The hydraulic capacity of the impeller is sometimes removed by the debris clogging it, creating an area of low pressure.
  6. Open Bypass Valve: Sn open bypass valve may be the one diverting the flow isn’t somewhere else.

How to select the right pump for any chemical process?

As the name itself suggests, chemical pumps are used in the process of making, using or disposing of chemicals. The materials used in their construction and designing are chosen in a way that they can withstand substances with high or low levels of viscosity, abrasiveness, and corrosiveness. 

When something is so susceptible to the state of the substance flowing through its interiors, it becomes crucial to be as accurate as possible during its selection. When it comes to zeroing on the correct chemical centrifugal pumps, there are many variables one has to keep in mind:

-The materials used for the construction of the pump

The materials used should be compatible with the chemical media as acids like sulfuric acid and hydrochloric acid may cause problems like corrosion.

There are two types of pump materials- metal and nonmetallic. Metallic chemical pumps are mostly made from stainless steel, a nickel alloy or titanium for protection against corrosion. Nonmetallic pump materials are rubber, plastic, ceramics, glass, etc. which are all used as pump materials for corrosive materials.

  • Pump size

If a pump of incorrect size is picked up, it will lead to operating problems within the pump fluid transfer system. Although owing to a built-in safety factor, mostly pumps are slightly oversized but if a pump is too big, it can make the centrifugal motor to be lightly loaded during operation. This, in turn, leads to lower productivity and higher operating costs. 

There are other issues that crop up as well like premature bearing failures, excessive vibration, increase in operating temperature and cavitation issues. But that doesn’t mean that one should go for an undersized pump as it has its own share of consequences. In an undersized chemical pump has to pump faster, straining their pump components, bringing down their suction capabilities, as well as fastening its wear, which may lead to failure.

  • Pump performance specifications

The proper performance of the pump includes maximum discharge flow, maximum discharge pressure (head), inlet size, discharge size, and media temperature.

How does the temperature of the Photovoltaic Model actually affect the power generation process?

Though highly efficient compared to other renewable energy resources, a solar PV module is severely affected by major fluctuations in temperature. When the temperature turns extremely excessive, the energy output of a PV system is hampered and results in unexpected energy loss. 

Why does temperature affect the solar photovoltaic model?

The efficiency of solar panels is negatively affected by an increase in temperature. In practice, photovoltaic modules are tested at a temperature of 25 degrees C (STC) – about 77 degrees F.- this is the Standard Test Condition temperature where the module’s nameplate power is determined. The heat can reduce energy output efficiency by 10 to 25%, depending on the solar panel’s installation location.  Increase in the temperature of the solar panel increases the output of current exponentially and lowers the voltage output linearly, severely reducing the solar panel’s capability to produce power. 

A panel’s heat tolerance can be deduced checking out the sheet provided by the manufacturer, which carries a term called the “temperature coefficient (Pmax.)”-  the maximum power temperature coefficient.  This gives you a fairly accurate idea about the percentage of power loss when the panel has to bear a temperature spike 1°C above 25°C. 

But there are multiple ways to ensure to bring this situation under control

• When installing the panels, place them in a way that they are a few inches above the surface of the roof so that there is enough space in between for convective airflow, allowing the panels to cool down. 

• It is a known fact that dark colours absorb more heat, so the best idea would be to make sure that the panels are constructed with light-coloured materials.

• Components like inverters and combiners are already doing the heavy work and as a result, get heated up. Keeping them in direct sunlight will only tip the soaring temperature over the edge, so it is a good idea to keep them in a  shaded area behind the array.

What are Solar Tracking Mounts? What are they used for?

Soalr Tracking Mount by VEMC

The world is struggling through the slow but unstoppable extinction of its power resources- fossil fuels yet it is still not utilizing the vast pool of renewable energysolar energy and is largely unaware of its various facets. While you may be aware of what are solar panels and their basic working dynamics, the type of mount they are placed on play a huge role in the percentage of energy they can produce. 

In terms of the radius of their movements, there are two types of solar mounts:

Stationary mounts– These hold the solar PV module in a fixed position. This acts as a disadvantage on days when the Sun is not in the desired angle and thus, the solar panels are not properly charged. 

Solar tracking Mounts– They are a far more advanced technology for mounting solar panels. As the solar trackers automatically move to “track” the sun’s shift in position and adjust the position of the solar panels, ensuring maximum energy output.

Where are solar trackers used?

They are typically used for solar panels which are ground-mounted and large, free-standing solar installations like solar trees. Residential solar projects mostly don’t employ them as they are built for large scale consumption, like in the utility-scale and commercial/industrial solar market.

There are two types of solar tracking systems: single-axis and dual-axis.

A single-axis tracker- This tracks the movement of the Sun as it rises and sets, i.e., from east to west as the panels are aligned along a north-to-south axis of movement.

A dual-axis tracker: Here the solar panels can move on two axes- north to south and east to west. This tracker is better than the single-axis tracker as it is more susceptible to the Sun’s rotation and position in the sky as well changes in the same due to seasonal variations.

Different types of Solar PV Panels. Roof Mounted vs Ground Mounted

A revolutionary discovery when it comes to renewable energy, solar panels are expected to replace fossil fuels across the globe, if used mindfully and employed innovatively. As we know, a single solar PV cell generates only 0.1 watts to 2 watts of energy. For its application in practical ways, such cells are connected to make a solar PV module in order to provide the required standard output voltage and power.

And while it is important to pick the right solar panel as per your needs, what matters is which mounting system will work best for your living space, fit into your budget, and energy needs.

The two types of solar mounting systems: Roof mount vs. Ground mount 

While the roof mount systems are fixed to the brackets on your roof, a foundation is built at ground level for ground mount systems.

Roof solar mounts 

The advantages of going for a roof mount system are rather few. Like it is less expensive, easier to install as well as utilizes less space. But the list of its cons is too long- 


  • Accessing the panel would be a hassle
  • The higher panel temperature results in lower panel output
  • Planning to replace your roof? Get ready to install the system again!
  • As there is constricted space on roofs, the size of the system has to be restricted

Ground Solar mounts

The requirement of intensive labor, expensive installation and permitting process, and not exactly an aesthetic addition to the space around your house.

But despite its cons, Ground mounts are the best option for you

They are easier to access, clean, and repair, if need be. Not only does it have a stronger racking, but its size also is not decided on how big the roof is and are producing higher energy inputs because of the cooler temperatures. Want to get your roof replaced? Go on, your panels are not in need of reinstallation!

Necessary Things To Know While Purchasing Water Pump Spare Parts

You cannot limit the uses of the water pumps within the industry itself. Its uses are found common in almost all areas like households, hospitals, schools, colleges, workplaces, etc. The water pump comes in handy for many reasons. For instance, you may live in an area where flooding occurs very frequently. You will need a submersible pump there to help clean up afterwards. In case if you live in a lavish villa, you will need a pump to fill your swimming pool with water. You may need it every day to pump out water from the borehole or water well. 

Whatever the need may be, you must know certain necessary things while purchasing water pump spare parts from water pump distributors in Navi Mumbai

The following are some of them:

GPM discharge capacity: All types of water pumps are measured in GPM discharge capacity which tells you how quickly, efficiently and powerfully the water is pumped out. To be precise, the GPM discharge capacity is defined as the rate at which the water flows from the source to the discharge point in gallons per minute. If the pump is intended for industrial purposes, you have to choose the one with a higher GPM discharge capacity.

Vertical suction lift: The vertical suction lift will tell you what the vertical distance is from the water source to the water pump. This will be useful when you are using the water pump for draining a pond or a flooded basement. With the help of a vertical suction lift, you will be able to know the distance to get it to the pump for the discharge of water.

Maximum head lifts: The maximum head lift is used to know what the total height of the pump is from the water source to the discharge point. This will also tell you how powerful the pump is and what distance it can move water over for the job that you need the pump for. 

Type of water pump: There are different types of water pumps, depending on the purpose, you can choose the best water pumps from Kirloskar water pumps Navi Mumbai. The different types of water pumps available with them are the following:

  • Submersible pumps
  • Water-boosting pumps
  • Self-priming pumps
  • Borehole pumps

The different types cannot be limited within the above list. Make sure that you research the different types of pumps and get the desired one for the intended purpose.

Checklist to be met before purchasing the spare parts of pumps

The following are the checklist to be met if you are buying spare parts for your pump:

  • Does the vendor maintain precise fits?
  • Do the spare parts contain the latest design changes?
  • Can the supplier ship the parts as he promised?
  • Can the supplier offer application expertise to solve pump problems, and avoid future failures?
  • Are the cost and delivery charges of the spare parts feasible?

Final thoughts:

Before you buy some random pump, spend some quality time in considering the above-mentioned points and make sure that you find the best one for your individual needs. You can also find the spare parts of pumps in Kirloskar spare parts dealers in Navi MumbaiResearching well on the different types of pumps available will allow you to get the best product that will be perfectly suited to what you require it for. 

Liquid or Slurry? Which Pump should you use?

If you’re looking to install a pump, your first consideration should be its purpose. What do you need your pump to do?

We can break this down into:

  • What type of medium do you need to transport or process?
  • How far do you need to move it?
  • What volume and at what flow rate will be required?
  • What power source do you have available? – electricity, compressed air etc.

In this post we’re going to focus on the first point. By understanding the type of material, whether solid or liquid or viscous, you will be able to identify the type of pump you need.

Flowable Liquids vs Slurry Mediums

Anything that needs to be pumped has a viscosity. For instance, water is 1 cPs while a much thicker liquid like a fruit pulp can be about 5,000 cPs. If it’s a slurry from a mine, this also is viscous to some degree. Slurry will also have a solids percentage which has to be taken into account. A general rule of thumb is, ‘if you can pour it, you can pump it’. There is a list of typical viscosities here.

Pumps for Different Mediums

Your first step should be to understand the nature of the product you are wanting to process or transport via a pump. If the medium pours easily without chunks of solid material present, then we can happily describe this as a liquid. But the real test is how viscous the liquid is. Likewise, if there are solids present, then this medium will require different equipment. There is a stark difference between pumping water which is thin and extremely fluid as opposed to oil or grease which is thick, or an abrasive medium which contains solids.

Let’s take a look at three common mediums and the pumps you might need:

  • Water: This is the simplest medium to transport. It’s easy to move around because it has low viscosity. Therefore either a centrifugal style pump, which includes submersible pumps, or even a pneumatic pump for dewatering, will suit your needs.
  • Oil: Now things get trickier. When a medium becomes oily, it’s still a liquid, but because it has higher viscosity you’re going to need a different style of pump. It needs to be able to withstand increased friction. Something like a gear or lobe pump which can handle higher viscosities. However, these pumps cannot run dry, so if your system needs a pump that may run dry at some point, you’ll need a tube or diaphragm pump.
  • Slurries and Abrasives: These mediums have deposits within them which are solid. Pieces of rock, metal, or other minerals etc. There are two considerations here. The first is to make sure that your pump is powerful enough to transport such medium, the second is to ensure that the pump is durable enough to withstand the abrasive nature of the medium. A peristaltic hose pump or a heavy duty slurry pump is ideal for such a situation.

Other Considerations

In some instances the medium you are using might be corrosive, so in this case you’ll need to choose a chemical pump which can process what you need while keeping an environment safe from contamination.
