All You Need to Know About the Types of Pumps

A pump is a mechanical device that moves a fluid (liquid or gas) forward through a pipeline or hose. They can also use them to create pressure by creating a suction (partial vacuum), causing the fluid to rise to a higher altitude. Pumps are divided into three major categories, and they are:- Direct lift pumps, displacement pumps, and gravity pumps.

Pumps work by systems which consume energy, either rotational or hydraulic. They operate using various sources of energy like wind power, solar energy, electricity, engines, etc. Pumps are also used in medical applications and also in industries.

Mechanical pumps are used to pump out water from wells and aquariums. They are used in the medical industry for biochemical processes in enrooting and making medicine. The working of pumps is quite similar to a compressor but the liquids used are different.

Submersible Pumps and Advantages

A submersible pump is one in which the whole assemblage is submerged in the fluid which needs to be pumped. The main advantage of this type of pump is that it prevents pump cavitation, where cavitation reduces the pressure of the liquid. It pushes the water pressure to the surface that creates a vacuum and dispels out the liquid. It is used in heavy oil submerging, which requires high pressure. These pumps reduce water shortage issues in outlying areas. These pumps are generally being utilized for drainage during floods, water spanking, or even areas where water clogging may occur. Submersible pumps are also used in fish tanks as filtration pumps.

Centrifugal Pumps and Their Purpose

Centrifugal pumps are those pumps in which fluid flows by using rotational energy. The fluid takes down the source of power to flow gradually. The impeller is a significant component in these pumps. The impeller is a kind of curved wheel that rotates the fluid flow. They have progressively become incompetent, and high pressure is required to be maintained thoroughly at a standard lower rate. Centrifugal pumps are used in chemicals with no leakage, used in sewage, heating, and ventilation. It is designed in a way to create low pressure at high capacity.

Know More About the Types of Pumps

There are several types of pumps that are used for different purposes. Let us know more about this. The different types of pumps are as follows:

  • Sewage pump

Sewage pumps carry sewage and dirty wastewater. They are majorly used in municipal wastewater treatment plants and also in buildings and several pumping areas. Areas not connected to municipal sewers are then connected to sewage pumps to get the drainage effective. Of course, sewage, a sewage pump, or a grinder pump is recommended to prevent blockage. These pumps transit sewage water or raw sewage. It also clears out wastewater and drains it out from industries and factories. It empties the septic tanks, cesspits, and sewage pump stations. It pumps out the raw sewage from garages and uses a sprinkler system.

  • Gear Pump:

A gear pump is a kind of displacement pump that moves in cyclic motion. It gives free flow rotational energy to its gears. There are two types of gear pumps - External with a limited number of parts while Internal consists of various small parts called gears. These pumps create high pressure and increase the capacity of fluids. It pumps out the oils and any kind of fluid with tremendous pressure.

It is used in chemical mixing and blending industries. It can be majorly used in agriculture and also for portable hydraulic applications. These pumps are perfect for high-pressure outputs.

  • Small Pump:

A small pump is a kind of submersible pump, i.e. it is a smaller version of the submersible water pump that is specifically light in weight and of small size. It also carries low consumption and also makes less noise. A small pump is a kind of centrifugal water pump requiring a motor to move it and rotate. This pump is also known as a puddle sucker as it can drain any shallow water. It is ideal for pools or other situations where water is clean. It can be used in small areas and also works faster than ordinary submersible pumps. One needs to choose where the water is going and also the pressure. The pump needs to be placed at the deepest part of the water. By hiring small pumps, you can easily clean your pools and flooded areas.

  • Booster pump:

A booster pump is a superior pressure pump with an impeller and is used to improve the water flow and pressure. The impeller is used for water entry, and it pushes it out with a lot of pressure. The booster pumps have a tank that creates hyper pressure inside the tank and increases the water flow. The impeller works electrically by an electric motor. It is a kind of centrifugal pump that increases fluids pressure and releases them at a high velocity from one place to another through the pipeline. Water storage tanks need to be used along with a water storage pressure tank as it delivers several benefits which increase the pressure in the tank. It moves in cyclic motion and increases the life of the pump.

Pumps: FAQs

Q. What are the 4 types of Pumps?

A. The four types of Pumps are:

  • Centrifugal Pumps
  • Vertical Centrifugal Pumps
  • Horizontal Centrifugal Pumps
  • Submersible Pumps.

Q. Which pump is more efficient?

A reciprocating pump or the positive displacement pump is more efficient as compared to a centrifugal pump. Reciprocating pumps work on a high and low-pressure basis.

Q. How many feet can a pump pull water?

A. Pumping shallow water up to a depth of 25 feet is possible. Submersible pumps or deep well jet pumps can pump water from wells up to a depth of 110 feet.

Q. What is the best brand of water pump?

A. The best brands of water pumps for regular use in India are Havells Hi-Flow Centrifugal Water Pump, Kirloskar Small Water Pump, Crompton Water Pump, Kirloskar Submersible Pump.
