As water pump dealers would tell you, the water pumps are used in construction sites. People use them for dewatering. This is a process whereby extra water that may have accumulated on the site is removed from over there. There are so many reasons why water can build up in these sites. It could be because of heavy rains. At times, the water table could be high as well. The pumps let you move the water within a short period. This helps in reducing the downtime as well. There are two main types of such pumps.
The types of water pumps
As water pumps distributors would tell you, there are two major variations of water pumps. These are positive displacement pumps and centrifugal pumps. Both these kinds of pumps are designed in such a way that you can move water to another place from where it is continuously. A centrifugal water pump makes use of a rotating impeller so that it can move the water within the pump. This also allows it to force the discharge flow. A positive displacement water pump delivers a specified amount of flow by way of mechanical shrinking and expansion of a diaphragm that is flexible.
Things to keep in mind for centrifugal water pumps
The centrifugal industrial water pumps are used in a wide range of water system and construction applications. They can do a lot more than mere dewatering. They can be used to pump water supplies of buildings. They can also work with pneumatic systems as well as ones where you do not need to use the suction lift. They are also used for pumping water from domestic wells. They can increase pressure in water intake lines as well. They can provide an uninterrupted pressure source used in the fire protection systems too.
Things to keep in mind for positive displacement water pumps
The positive displacement of Kirloskar water pumps is also referred to as rotary pumps. They are effective. This is because they can remove air from the lines, and this does away with the need to bleed the air as such. They are also extremely handy when it comes to dealing with liquids that have a high amount of viscosity. The main issue with these pumps is that they need a really small clearance between the outer edge of a rotating pump and the pump itself.
Features and specifications of these pumpsAs you would get to know from your water pump dealers, there are several important factors that you must take into consideration at the time of selecting such a pump. In power, you must look at the horsepower and the flow rate. In the material, you must check if it has been built with weather-resistant materials that are useful when it comes to applications where the pump could be exposed to the natural elements. You also need to check the fuel and the motor type over here, and the total head discharge.
Yes, you read it right.
Solar energy is all set to become a cheaper source of energy. But Solar energy generation
involves a significant capital investment for installation. Wouldn’t that make
it more expensive than fossil fuel-generated energy? Not really. Here’s why:
Advances in technology are making Renewable Energy cheaper to use than ever before.
The use of Batteries and Battery Backup ensure that excess energy isn’t lost if there isn’t any immediate demand for it. It makes having a Residential Solar Panel a more sustainable option because if you store extra energy, you won’t have to buy additional units of electricity during nights or cloudy days.
The prices of fossil fuels are significantly high and are dependent on many factors including international relations, politics, etc.Meanwhile, sunlight is universally available, free to use and using it for electricity generation is better for the environment.
These are only the basic factors that explain why solar energy is cheaper than its nonrenewable alternatives. Many other factors also play a role in lowering its prices.

If you’re looking to invest in a PV system for a curved rooftop, you should first read up on the different components it’s got. This will help get a clear idea of the amount of space and money you need to account for when it comes to the installation of the system.
So, what are the main components of such a system?
Solar PV Panels: A panel is comprised of many solar cells. Each cell absorbs light and produces DC (Direct Current) electricity. DC can be used to charge Batteries but if you want the system to provide electricity to your household or commercial space, the DC current needs to be converted to AC (Alternating Current). That brings us to:
The Main Panel/Inverter: This is where the DC supplied by the PV cells is converted to AC and supplied to your household/commercial space.
Battery Backup: This provides Storage for excess power produced during times of peak sunlight for use during nights, cloudy days, etc.
Electric Meter: This calculates the amount of electricity being generated and consumed and is essential for solar net metering (click here to know more).
Safety Equipment: This may include safety disconnect switches or surge protection devices for instance. It adds safety to the system which makes it possible for Residential Solar Panels tobe risk-free for residents.
These components are the bare minimum you’ll need for your system. There are more components like wiring, a power conditioning unit, mounting equipment, grounding equipment, etc. that also need to be invested in.

You may be considering switching to Renewable Energy. In that case, congratulations, you’ve made a great decision. But switching to a greener energy source involves many more choices. One such choice is whether you should go for Solar Energy or Wind Energy.
suggestion: Go for Solar Energy.
Yes, Wind Energy has its own benefits, be it the possibility to generate power even at night, more efficient electricity generation in some cases, etc.
However, in a country like India, Solar Energy is a safer bet than Wind Energy.
makes Solar Energy better?
Minimal fluctuations in energy output. Winds are more unpredictable than sunlight, hence Solar Energy is more likely to provide consistent patterns of power generation.
Suitability for most regions. SolarPV Panels can be installed almost anywhere, be it in a village or an urban region. However, wind turbines can only be installed in windy regions, which limits this energy source’s geographical flexibility. Solar panels also require lesser space than wind turbines, hence,for example, a Solar Panel in Mumbai may be a more feasible option than wind turbines in Mumbai.
No disturbance. Wind turbines tend to be noisy and they can also injure birds sometimes. Solar panels, meanwhile, have no moving parts, which makes them more suitable in many cases.
Easier maintenance.As a result of the lack of moving parts, Solar PV Panels require significantly lesser maintenance and are more hassle-free.
The Kirloskar centrifugal pumps – and all other centrifugal pumps for that matter – are a kind of a dynamic axisymmetric turbomachine that work-absorbing. Industries use them to move fluids. In this case, they get help by changing the rotating kinetic energy to hydrodynamic energy that you need for the flow of the fluids. This rotational energy comes from an electric motor or an engine. The fluid, in this case, enters the impeller that is present close to the turning axis. Before this, it flows outward in a centrifugal motion. It flows into the volute chamber that is also referred to as diffuser. Industries use these pumps in areas such as water, petroleum, sewage, and petrochemical pumping.
How do these pumps work?
As the centrifugal pumps distributors would tell you, these pumps work like most other pumps out there. This is in the sense that they also convert rotational energy, which is coming from the motors to the energy that you get in moving fluids. In this case, a part of the fluid goes into the kinetic energy that is contained in the fluids. This fluid enters via the eye of a particular casing. It normally gets caught up in the impeller blades. After this, the fluid gets twirled in a vague and outward manner.
Vertical centrifugal pumps
You can always buy a centrifugal water pump in India from the top brands such as Kirloskar. The vertical centrifugal pumps happen to be known as cantilever pumps as well. They are built in such a way that they contain a shaft that is unique to them. They also have a bearing support configuration. It is this particular design that permits the volute to hang in on the sump even as the bearings are placed externally. This kind of pump does not use any stuffing box to seal the shaft. It can use throttle bushing though.
A centrifugal pump in India can generate the froth and take care of the same as well. These pumps come in handy when it comes to separating rich minerals like bitumen from sand as well as clays. These pumps normally contain air that would block the traditional pumps. This can lead to significant loss of the prime as well. When these pumps are used in the paper and pulp industry the impeller are drilled with holes. In this case, the air goes out to the back of the impeller in question.
Multistage centrifugal pumps
You also get Kirloskar centrifugal pumps that can be regarded as multistage centrifugal ones. The suppliers of these pumps design them in such a way that they have at least 2 impellers. These can be put over on the same shaft or they may be mounted on separate shafts as well. In the journey, in this case, the fluid is directed towards the center. In this case, it makes its way towards the discharge. This happens over the outer diameter. In the case of the outlets with higher pressure, the impellers can get connected in the series. In case of higher flow outputs, these impellers can get connected in parallel.
Spoiler alert: It’s good news. One of the countless benefits of installing solar PV Panels is that once invested in, they last for 20-30 years with minimal maintenance. But before you invest in them, it is important for you to know everything about the lifespan of this source of Renewable Energy.
What does ‘lifespan’ refer to? When we say the Life of Renewable Energy, in this case, is 30 years, it doesn’t mean that your solar panel will stop working after 30 years. It simply means that it won’t function at optimum levels. The panel will still continue to work for many more years.
Solar panel degradation rate So now we know that a panel may not be 100% efficient after a few decades. But at what rate does it degrade? That depends on the quality of the panel you choose. On average, Solar PV Panels degrade at a rate of 0.5-0.8% per year. This means that if a panel is operating at 100% efficiency, this will drop to 99.5% or 99.2% respectively after a year. This isn’t a cause for worry because your panel will still work fairly efficiently for decades. At this slow a rate of degradation, you’re in for many decades of hassle-free Renewable Energy generation.

Repairs? You may be surprised. Solar panels are known to be very low maintenance, however, it’s always prudent to check up on them at least once in six months to ensure that nothing stands in the way of efficient renewable energy generation.
What are some signs you need solar repairs? Dirt buildup. This is the simplest thing to look for. Since your panel is outdoors, it is subjected to dust, debris and other pollutants. These could obstruct sunlight reaching your panel, and in some cases, may also cause damage to the panel if not dealt with properly. Damaged glass. The glass used on PV Panels is built to withstand the harshest of conditions. However, in rare cases, as a result of heavy objects falling on your panel, you may notice cracks on inspection. Here, it’s crucial to get them fixed to avoid further issues. Damaged metal parts. The panel is supported by a rack and several smaller parts that hold it in place. While these are designed to last for years, over time, they may begin wearing out. If you notice rust on any portion of the rack, your panel needs immediate repairs.
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.
The thing with fire fighting pump setis 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 Indiathis 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 distributorshave 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.
