How 19 types of pumps work


When it comes to moving fluids, pumps play a vital role in various industries and applications. There are numerous types of pumps, each designed to serve specific purposes. In this article, we will explore the functioning of 19 different types of pumps and their applications.

Centrifugal Pumps

Centrifugal pumps are one of the most common types of pumps used in industries. They work on the principle of centrifugal force, which is generated by a rotating impeller. As the impeller rotates, it creates a low-pressure area at the center that draws fluid from the inlet. The fluid then moves outward due to the centrifugal force and exits through the outlet. Centrifugal pumps are widely used in water supply systems, irrigation, HVAC systems, and chemical processes.

Positive Displacement Pumps

Positive displacement pumps operate by trapping a certain volume of fluid and then forcing it into the discharge pipe. These pumps create a fixed flow rate, regardless of the discharge pressure. One of the common types of positive displacement pumps is the reciprocating pump. It uses a piston or plunger to generate pressure and move the fluid. Another type is the rotary pump, which consists of gears, lobes, or vanes that rotate to trap and displace the fluid. Positive displacement pumps are often used in oil and gas, food processing, and pharmaceutical industries.


Pumps are essential devices for various industries, allowing the efficient movement of fluids. Understanding how different types of pumps work is crucial in selecting the right pump for specific applications. Whether it’s a centrifugal pump for large-scale water supply or a positive displacement pump for precise liquid transfer, each type has its own unique working principle and application. With continual advancements in pump technology, industries can expect even more efficient and reliable pumping solutions in the future.
