What Is a Positive Cavity Pump?

A positive cavity pump, also known as a progressive cavity pump, is a type of positive displacement pump. It moves fluid by forming cavities between a rotating metal rotor and a static stator. As the rotor turns, these cavities progress along the pump body, carrying the fluid with them in a smooth, non-pulsating motion.

Because of their ability to handle viscous, abrasive, and shear-sensitive fluids, positive cavity pumps are the go-to for industries dealing with difficult pumping conditions.

Key Features and Benefits

Here’s why a positive cavity pump stands out:

✅ Smooth, Consistent Flow

Unlike centrifugal pumps, there’s no pulsing or surging, which is essential for dosing and metering.

✅ Handles Thick and Abrasive Fluids

Sludges, pastes, slurries, and even grit-laden liquids are handled with ease.

✅ Self-Priming Capabilities

These pumps can draw fluid from below-grade tanks, even in challenging suction conditions.

✅ Low Shear Operation

Ideal for delicate or shear-sensitive materials, such as food-grade products or polymer additives.

✅ Directional Flexibility

Many models can operate in reverse, offering easy cleanout or system versatility.
