What is a Cavity Pump?

A cavity pump is a positive displacement pump that moves fluid through a sequence of sealed cavities formed between a rotor and stator. The pump operates by creating a series of expanding and contracting cavities that transport fluid smoothly from the inlet to the outlet without causing agitation or pulsation.

This design makes cavity pumps ideal for handling viscous, abrasive, shear-sensitive, or solids-laden fluids. They can pump a wide range of materials, including sludge, slurries, oils, and chemicals, with minimal damage to the product and high volumetric efficiency.

How Does a Progressive Cavity Pump Work?

A progressive cavity pump is a positive displacement pump that moves fluid through a series of sealed cavities. Its core components include a single helical rotor and a double helical stator made of an elastomer material.

As the rotor turns inside the stator, it forms cavities that progress from suction to discharge. These cavities remain sealed from one another, ensuring a smooth, pulseless flow of fluid.

Step-by-Step Working Principle:

Rotation begins: The rotor rotates inside the stator.
Cavities form: As the rotor turns, cavities open at the suction end.
Fluid is captured: Liquid enters the open cavity.
Cavities travel: As rotation continues, the cavity progresses forward along the pump body.
Discharge phase: Fluid is pushed out the discharge end without pulsation or turbulence.

This design enables precise flow control and exceptional handling of viscous, abrasive, or delicate fluids.

Key Features of Progressive Cavity Pumps

Self-priming and able to handle suction lifts
Steady, pulse-free flow regardless of fluid type
Excellent for high-viscosity or abrasive fluids
Low shear pumping for sensitive applications
Reversible flow direction by changing motor rotation
Handles solids, slurries, and suspended particles

This makes them ideal for applications where centrifugal pumps would struggle or fail.

Where Are Progressive Cavity Pumps Used?

PC pumps are versatile and widely used across multiple sectors. At MultiTorque, we often supply them for:
