The Impact of Viscosity on Pump Performance

If you’re a pump owner, you would understand that transporting thicker liquids is quite a different experience. Viscosity represents the resistance that a liquid offers to the flow. It doesn’t only take longer to displace but also impacts your pump’s performance. 

VEMC is one of the leading Kirloskar pump distributors based in Mumbai, and in this blog, we explain how viscosity affects your pump performance.

As your water pump dealer may explain, viscosity has an effect on some of the most critical pumping parameters. Let’s see how.

  1. Flow rate: To put it simply, with an increase in viscosity, there is a decrease in the flow rate of a pump. However, a number of other factors such as physical properties, geometry of the tubing, temperature and the distance of liquid from the pump may also play a moderating role.
  2. Head: Viscosity has an extraordinary and negative effect on pump performance. With an increase in viscosity, there is a dramatic drop in the head.
  3. Efficiency: While pumps may still be able to displace highly viscous liquids, they will inevitably hit a point of diminishing returns due to a drop in efficiency. This means you may require a more powerful pump which will consume more energy to move a more viscous liquid.

Which pump is suitable to move your liquid type?

When selecting a pump on the basis of fluid properties, there is no one-size-fits-all. Now that it is clear that higher viscosity affects a pump’s performance negatively, let’s take a closer look at which pumps are best suited for moving your viscous liquids.

While centrifugal pumps are good enough for low viscosity liquids like water, their performance and efficiency may reduce significantly for more viscous liquids. These pumps may draw more power when transporting thicker liquids causing wastage of energy and piling up of electricity bills. For such liquids, the best pumps are positive displacement pumps such as diaphragm pumps, hose pumps, vane pumps and gear pumps. These can operate at lower speeds and at variable flow rates, delivering a constant flow of the fluid at desired speed. 

Viscosity is an important factor to consider when selecting the right pump, and also the size of instrumentation, piping, valves and filters. Appropriate selection of these items is necessary to account for friction loss due to viscosity.

5 Ways Solar Metering Can Maximise Your Energy Savings

Whether in domestic, office or industrial setting, solar energy is catching up as one of the most preferred alternative energy sources. The growing efficiency and energy savings offered by solar PV systems across the world have provided further headwinds to this trend. 

VEMC is the leading solar energy company based in Mumbai, and in this blog, we take you through the 5 ways in which solar metering can maximise your energy savings.

1. Lower electricity bills

For starters, installing a solar PV system on your rooftop will instantly cut your electricity bills as the burden will shift away from your grid. Solar panels support a wide range of appliances such as TV,  air conditioners, refrigerator, lights, dishwashers , etc., depending upon their capacity. Users have in fact reported a reduction of up to 90% of their bills.

2. Government incentives

Solar energy is being incentivised by governments across the world owing to its contribution towards a green, carbon-neutral future. Whether in the form of subsidies, tax breaks or other incentives, you can benefit greatly from generating electricity from your rooftop solar plant. VEMC, a leading solar installation company, can also get you more information on the incentives available in your city.

3. Alternative heating system

A significant portion of your electricity is consumed by heating devices like geysers and cookers. The charges that are accrued by running these heating devices can be somewhat neutralised or completely eliminated using solar panels. This is a great way to capture the already available and abundant energy of the sun to heat up your liquids, food or homes, in a clean way.

4. Net metering

Net metering is an ingenious way to sell and keep a record of the excess energy that you export to your electricity grid. In case you do not use all the electricity that your solar panels produce, you can sell the surplus to your local supplier and earn money. At the very least, net metering can enable you to offset your energy bills. All you need is a ‘net meter’ which keeps a record of electricity imported and exported.

5. Higher property value

Finally, solar panels are known to increase property value in the long run. Research suggests that homes with solar panels are also more marketable or put simply, they sell faster! This is a rather indirect, yet significant value that solar panels bring to your property.

When it comes to energy savings, solar PV systems are one of the leading solutions worldwide as they offer a number of ways to cut down on your energy costs. We’ve seen above how they reduce electricity bills and even enable you to monetise your solar PV system through net metering.

Sizing your solar system: finding the perfect balance for your energy needs

Having a solar power system is a smart way to meet your electricity needs at home and business. However, to make sure that you are able to fulfil your needs without wasting any energy, sizing your solar system is necessary. This allows you to avoid over or underinvesting in your solar system and getting just the perfect one suited for your needs. VEMC is the leading solar panel installation company in Mumbai and in this blog, we tell you how to perfectly size your solar system.

Factors to consider in sizing

  1. Consumption: 

Higher the levels of usage or consumption, more will be the size of the solar power system required. This means a bigger solar power system will be needed in a business or industrial setting as compared to a domestic one.

  1. Location: 

Where you live also impacts the sizing of your solar power system. If you live in a tropical region that gets plenty of sun all year round, even lesser solar panels will produce good amount of energy. However, in temperate regions, you my require bigger solar systems to make up for the low sunlight during the winter season.

  1. Climate: 

Although climate is largely a function of geographical location, some places neverthess are too cloudy or rainy due to other factors like altitude, monsoons etc. If you experience too much of overcast weather during the day, this will also necessitate installing a bigger solar power system.

  1. Efficiency: 

Highly efficient monocrystalline solar panels produce plenty of energy over a limited surface area. This also plays a role in determining the size of your solar system.

A step-by-step guide on sizing

  1. Calculate your usage: 

For starters, you must be aware of your annual energy usage. You can find this from your electricity bill which may also exhibit the peaks and valleys of energy consumption. Find out the average usage of electricity per day.

  1. Find out your peak sun hours: 

The peak sun hours vary according to your location and climate. To make the most of your solar power, find out your peak sun hours using a sun hours chart.

  1. Calculate the size of your solar power system: 

To find out the size of a solar power system that would be most suited for your needs, divide your daily energy requirement (in kWh) by your peak sun hours. This will give you a kW output. Divide this by your solar panel’s efficiency and you’ll get an estimate of the number of panels you’ll need.

Alternatively, if you know the “efficiency factor” of the solar panels (lets say 0.2), here’s the formula to find out the size of your solar power system:

(Daily kWh / Average sun hours) x 0.2 = Size of solar system

Proper sizing of your solar power sytems is very important to ensure optimal performance and cost effectiveness.

10 Solar Energy Hacks for the Next-Generation Solar Power User

If you own a solar power system, you would want to get the maximum out of it. Luckily, there are plenty of hacks to enhance the efficiency and output of your solar panels. These range from choosing the right type of panel to maximizing their exposure. VEMC is the leading solar power company based in Mumbai, and in this blog, we share 10 solar energy hacks that every next-gen solar power user ought to know.

  1. Use monocrystalline grade A panels

How well your solar panel performs depends a great deal upon the quality of the panels. Monocrystalline Grade A panels are by far the best when it comes to efficiency and productivity.

  1. Increase efficiency using anti-reflection coating

These allow cells to absorb more rays rather than reflect them back. Without these, upto 30% radiation is wasted. 

  1. Get a professional to install your solar panels

Ensure that the installer you have hired possesses the required skills and certifications. Do a background check and find out what others are saying about their past installations.

  1. Ensure the right orientation

In the northern hemisphere, the best orientation for maximum exposure is the geographic south. On the other hand, if you live in the southern hemisphere, it is best to have your panels face the north. If thats not possible, have them face the west as the last resort as this is the direction of the sunset. You can expect more value from energy collected later in the day.

  1. Track the sun with your panels

Trackers enable you to follow the sun as it passes across the sky. While these are most common in commercial solar farms, smaller ones can also be used domestically.

  1. Don’t use too many devices simultaneously

Use your stored power for a longer time period by avoiding too much drain in a short span. As much as possible, stagger your usage over a longer time horizon.

  1. Clean with plain water and sponge 

Dust and debris can block the solar radiation from reaching your panels. To wipe it away, use clean water and a non-abrasive sponge. This will avoid unnecessary scratches on the cell surface. Also, do not use pressure washers to avoid damage. In case there is any stuck-on grime, just use some dish detergent and water.

  1. Use LED bulbs

LED bulbs use at least 75% less energy as compared to incandescent bulbs. By installing LED bulbs in your house or facility, you can reduce energy consumption and prolong the supply significantly.

  1. Use maximum utilities during the day

When you’re using your devices such as dishwashers during the day, you mostly use solar energy. This enables you to avoid the costs of power from the grid.

  1. Use solar power for innovative devices

Besides the usual solar panels, use your solar power in innovative ways. These include having solar cookers, solar geysers, heaters etc. This will allow you to take a huge burden off your conventional supply.

Steps Involved in the Mechanical Seal Test Process

If you are a pump owner, you must be on top of all the processes and techniques of pump maintenance. One such crucial process is the mechanical seal testing. Mechanical seals control leakage of liquids in pumps and other rotating devices. The purpose of testing therefore is to analyse its effectiveness in preventing leakage at various speeds and sizes. VEMC is the leading Kirloskar dealer in Mumbai, and in this blog we tell you all you need to know about mechanical seal testing.

Testing process

  1. Preparation: 

Mechanical seals are tested in accordance with the API standard 682. This requires that all the seal types (A, B and C) be tested in all seal arrangements, single seal, pressure-less and pressurized dual seal. It specifies tests with diameters of 50 mm and 100 mm and speed of 3600 rpm. Further, each seal must be tested with four different media.

  1. Dynamic phase: 

The dynamic phase of the mechanical seal test is conducted at a constant pressure and temperature at the speed of 3600 rpm. The test has to be performed for more than 100 hours at base point conditions.

  1. Static phase: 

The static phase of mechanical seal testing takes place at constant pressure and temperature at 0 rpm for 4 hours.

  1. Cyclic phase: 

Tests are conducted at base point conditions at a speed of 3600 rpm till equillibrium is attained.

After this, the seal chamber pressure is dropped to 0 psi so as to vapourise the fluid. Base point pressure is then re-established.

Next, the seal chamber fluid temperature is dropped to 20 degrees C and then base temperature is re-established.

Finally, the fluid temperature in the seal chamber is raised to 80 degrees C, seal flush turned off for 1 minute and then the test is shut down (0 rpm) for 10 minutes.

Preventive measures to maintain the integrity of your mechanical seals

Leaking mechanical seals could be a source of serious housekeeping hazard, health concerns and business issues in your facility. To avoid repeated mechanical seal testing, it would be best to maintain it using some very simple but effective ways:

  1. Choose a mechanical seal based on your weather conditions. 
  2. The liquids being pumped are also vulnerable to changes in pressure, temperature etc. Although most liquids act as lubricants for your seals, nevertheless being aware of their nature helps you choose better.
  3. Be aware of the actual nature of leakage through a seal. This could be due to a shaft that has bent or bad bearings.
  4. Try to reduce pump vibrations as much as possible. Excessive vibration contributes to the cavitation of pump body and deterioration of component parts like seals.
  5. Finally, rather than running the pump dry, make sure you maintain proper lubrication.

The Role of Pumps and Air Compressors in the Circular Economy

As opposed to a linear economy which proceeds through the stages of ‘take-make-waste’, a circular economy is restorative and regenerative. The economic activity in a circular economy builds and rebuilds the overall health of the system. It aims at decoupling growth from the consumption of finite resources. The three most significant features of a circular economy are resource efficiency, waste reduction and closed-loop systems. A circular economy offers enduring benefits like environmental sustainability, economic growth and job creation.

VEMC is the leading air compressor dealer in Mumbai, and in this blog we take you through the role of pumps and air compressors in a circular economy.

Industries that rely on pumps and air compressors

A range of industries such as manufacturing, wastewater treatment and energy production rely on water pumps and air compressors. Here are some of the major functions performed by them:

By pumps:

  1. Transporting fluids such as chemicals, oil, water etc. from one place to another
  2. Removing pollutants and contaminants from fluids
  3. Providing the necessary pressure required for industrial processes
  4. Mixing and blending liquids

By air compressors:

  1. Pushing and propelling gases through pipelines
  2. Blow cleaning and spray painting operations
  3. Powering pneumatic tools such as drills, abrasive blast equipment etc.
  4. Shifting AC refrigerants

All the above-mentioned functions consume energy. To create and sustain a circular economy, it is important that energy efficient pumps and compressors are used, so that operations are performed at peak levels without wastage of energy.

Recycling and remanufacturing pumps and air compressors

Air compressors and pumps that are in use for a very long time will inevitably undergo wear and tear. This will affect their performance and energy efficiency. However, if these equipment are procured from trusted manufacturers like VEMC, you can expect longevity and consistent performance. This is not just great for your business as it avoids sudden breakdowns, loss of business and unexpected capex investments, but also for the circular economy as it avoids wastage of resources and lowers the carbon footprint. Besides, techniques like retrofitting can offer a second life to your equipment while enhancing their performance and efficiency.

Role of compressors and pumps in a circular economy

One of the most important aims of a circular economy is to reduce wastage and lifespan costs of equipment. This is ensured in three main ways:

  • Products like compressors and pumps which are designed keeping the concept of circular economy in mind, aim to extract maximum value out of resources. As soon as the products reach the end of their service life, their parts are salvaged and re-processed to leave as little waste as possible. 
  • Product design also ensures that as little wastage of material during operations (through friction) takes place. The simplicity of design to avoid as much metal-to-metal contact can help reduce lifetime costs of the equipment significantly. 
  • The product designs also ensure minimal consumption of energy and enhanced operational efficiency. This contributes to lower carbon footprint and energy savings throughout the service life of the product.
