7 Ways in Which Solar Energy Benefits Us

We’re always told solar energy, being Renewable Energy, is good for us. But how?
As Global Warming is on the rise, the Earth is exposed to more sunlight and heat. PV Panels make use of this adversity to generate electricity. Apart from this, there are many other benefits to using solar energy.

1) Saves Oil: In many places, crude oil serves as the main source of energy. With rising oil prices, solar energy can be easier on the pocket in addition to being a greener energy source.
2) Creates Employment: The installation, maintenance, commissioning, etc. of PV Panels, Batteries, etc. can generate a lot of employment.
3) Equivalent to Taking Cars Off the Roads: Fewer cars lead to a fall in greenhouse gas emissions. Similarly, using a Residential Solar Panel reduces demand for Non-Renewable Energy sources that emit greenhouse gases. As a result of this, the emission of harmful gases like carbon dioxide, carbon monoxide, etc. is significantly reduced because solar PV systems don’t release any greenhouse gases.
4) Equivalent to Planting Trees: Planting trees helps absorb excess carbon dioxide from the atmosphere. Solar energy, on the other hand, prevents carbon emissions by substituting Non-Renewable Energy. Hence, the two have the same effect.
5) Reduces Health & Environmental Damages: Solar energy is clean energy and doesn’t produce any harmful by-products. This makes it a safe form of electricity.
6) Saves Water: Coal power plants use vast amounts of water to process and clean the fuel. Solar energy generation, meanwhile, doesn’t need any water since the “fuel” is sunlight.
7) Reduces CO2 Emission: Since solar power generation doesn’t burn any carbon-based fuels for energy, it doesn’t emit any carbon dioxide.

Basic Understanding Of Industrial Water Pumps

The thing with fire fighting pump set is that they are basically meant to work at one point only. This means that such a pump has only one point of flow and head. This can be described as a hydraulic condition. It is also referred to as BEP (Best Efficiency Point) as well as the best operating point. It may have a published set of curves. However, as experts would tell you, this is merely a commercial compromise. For most end-users, the process of getting a pump built and designed to suit their special hydraulic conditions would be really expensive.

Paying attention to the published curves of the pump

Even if you have bought Kirloskar water pumps India this is something that you must do. The pump performance covers of the makers are based on clear water. The approximate mark here is 65 F. This is unless something else has been stated by the makers. You can be sure that they would not be corrected with respect to fluid viscosity. Even when they have started a horsepower it may or may not be corrected for specific viscosity and gravity.

If the published pump curve stops it is for some good reason

If centrifugal pump distributors have published a particular pump curve and if it stops at some point of the head and flow there is definitely a good reason for the same. You should never operate your pump at the end of the curve. If the pump was capable of producing a better performance the makers would have extended the curve themselves. If you operate it till the end of the performance curve or near you can be sure you would be facing issues in the future.

Pumps can be stupid

As the best water pump dealers in Thane would tell you, these pumps can be rather stupid. You need to understand that a centrifugal pump is basically a machine. It has a certain set of fluid properties, operating speed, and impeller geometry. It is because of these characteristics that it would react a certain way to the system that has been installed. The flow and head point of the pump will be a crossing point of its system curve and performance curve. The system curve would basically dictate where these pumps would operate. 

You have to understand the system curve

The system curve can be said to be representative of all the friction as well as the pressure and static head that has been baked into the same.  

A fire-fighting pump set will also have a velocity head. However, under normal circumstances, it would be so small that you would not really be concerned about it.


Your pump would never suck fluids. This is a misunderstanding that is surprisingly common. You need to understand that there has to be another energy source that would be needed in order for the liquid to get to the pump. Normally, the best examples of such sources of energy are atmospheric pressure and gravity.

Choosing Right Pump For Fire Hydrant And Sprinkler Application

Metro cities are getting filled with people seeking to make their dream come true and in an effort to do so, few succeed and looking at their success stories more people are coming towards metros, with increase in the population there is demand for housing. Metros like Mumbai have limitation in growing horizontally which leads it to the vertical expansion. It has become common to see 50 to 60 floor building and few of them touching almost 100 floors. This means developers in cities like Mumbai are focused on effective use of the space they have and don’t want to waste any of it.

This shift can also be seen in the pumping industry, where most of the builders used to procure standard horizontal end suction pump or split case pump are now shifting to Vertical pumps which consumes less space compared to horizontal pumps.

There are two major applications in Building and construction sector.

  1. Fire Fighting pumps
  2. PHE pumps (Public Health Engineering)

In Fire Fighting application the flow rate usually are 1620 LPM, 2400 LPM, 2800 LPM, 2850 LPM & 3200 LPM and Pump Head could be anything above 70 Meter

In PHE the flow rates are not as high as fire fighting application and the pumps required have to be of high efficiency as they are one of the continuously running equipments in any building. The requirement for compact size and high efficiency than single stage end section pumps for the same head and flow, Inline pumps are in demand for PHE application.

To cater High flow rate at high head we use pumps which are manufactured by casting process which offers extremely good pressure handling capability for the flows of fire fighting application, PHE pumps are of low flow which can be catered by pumps which are made from sheet metal. These sheet metal pumps are mostly Inline type.

While choosing pumps for Fire Fighting Hydrant & sprinkler application, people tend to confuse vertical multistage pumps with Vertical inline pumps but they are completely different and as per IS 12496 standards Inline pumps are not suitable for Fire Application except jockey pump application where the flow rate is 3% to 7% of total Flow.
