Positive Cavity Pump: Powerful Precise Fluid Movement 2025

Positive Cavity Pump

When your process demands precision, consistency, and the ability to handle tough or viscous fluids, you need a positive cavity pump. These workhorses are relied on in industries like wastewater, mining, food, agriculture, and chemical processing—where smooth, controlled flow makes all the difference.

At MultiTorque, we supply and service high-quality positive cavity pumps and spare parts throughout Australia. Whether you need a full pump skid or just a replacement rotor and stator, we’ve got what it takes to keep your systems moving.


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.
