What is A Pump?

A pump is a machine that pumps energy liquid. It is a machine that converts the mechanical energy of the prime mover into the potential energy of the pumped liquid. Driven by the power machinery, it can pump liquid from a low place to a high place or far to serve production.

The pump can pump water, oil, acid-base solution, liquid metal, paper pulp, mud, etc. The pump used for pumping water is called a water pump.

Water pumps are used for agricultural irrigation and drainage, improving the ability of agriculture to resist natural disasters, increasing production, ensuring income, and providing material conditions for the realization of mechanization and water conservancy in agriculture.

Classification of Pumps

Following are some of the pumps under both categories (it is impossible to list all):

Classification of Dynamic Pumps

Dynamic pumps impart velocity and pressure to the fluid as it moves past or through the pump impeller and, subsequently, convert some of that velocity into additional pressure. It is also called Kinetic pumps

Centrifugal pumps
Vertical centrifugal pumps
Horizontal centrifugal pumps
Submersible pumps
Fire hydrant systems

Classification of Displacement Pump

Displacement pumps, the moving element (piston, plunger, rotor, lobe, or gear) displaces the liquid from the pump casing (or cylinder) and, at the same time, raises the pressure of the liquid. So displacement pump does not develop pressure; it only produces a flow of fluid.

Diaphragm pumps
Gear pumps
Peristaltic Pumps
Lobe pumps
Piston Pumps

Selection of pump

We have different types of pumps, out of that pump(type of pump) how can we choose the desired pump as per our requirement? followings are some useful tips for selections of pumps.
