Introduction to Rotary Pump

A rotary pump, sometimes known as a positive displacement pump, operates by using rotating parts to generate fluid motion. Unlike other types of pumps, such as centrifugal pumps, which rely on spinning impellers, a rotary pump uses rotating elements to create suction and discharge pressure.

Rotating Mechanism

The essential feature of a rotary pump is its ability to transfer fluid through a cyclic process. Generally, this pump consists of two or more interlocking rotating parts, such as gears or lobes, housed within a casing. By meshing with each other, these rotating components create chambers that act as containers for the fluid being pumped.

  • The primary function of the rotating mechanism is to create a sealed space and separate the fluid inlet from the outlet.
  • As the rotating parts move, they trap a certain volume of fluid in the chambers created by their interlocking design.
  • This trapped fluid is continuously carried along by the rotating elements until it reaches the discharge side of the pump.
  • Finally, the fluid is expelled into the discharge system, such as a hose or pipe, due to the increasing pressure in the chamber.
