What Is a Progressive Cavity Pump?

A progressive cavity pump (PC pump) is a type of positive displacement pump known for handling thick, abrasive, and shear-sensitive fluids with ease. It uses a single-helix rotor turning inside a double-helix stator, forming cavities that progress through the pump body to move fluid in a smooth, consistent motion.

This unique mechanism allows for gentle handling of the fluid, minimal pulsation, and a steady flow rate. As a result, progressive cavity pumps are widely used across demanding Australian industries such as mining, wastewater treatment, agriculture, and food processing.

How Does It Work?

As the rotor turns within the stator, it creates sealed cavities that progress linearly. These cavities trap the fluid and carry it through the pump. The design provides:

• Self-priming up to 9 metres

• Low-shear, pulse-free flow

• High discharge pressure (up to 24 bar)

• Excellent solids-handling capability

It’s ideal for abrasive sludge, polymer solutions, fruit pulp, drilling mud, and even cementitious slurries.

7 Reasons to Use a Progressive Cavity Pump

1. Superior for Viscous and Abrasive Fluids

Progressive cavity pumps shine where other pumps struggle. They easily transfer thick sludge, heavy oils, wastewater grit, and abrasive mixtures. The rotor/stator design reduces wear and tear, extending service life even under punishing workloads.

2. Gentle on Products

The low-shear action ensures fragile materials maintain their integrity. In the food and beverage industry, they’re used to pump yogurt, honey, jams, and sauces without altering texture or structure.

3. Self-Priming Capability

PC pumps can self-prime and lift fluid from depths of up to 9 metres. This makes them excellent for underground sumps, pit dewatering, and mobile tankers in remote locations.

4. Consistent, Accurate Flow

These pumps deliver consistent flow rates, ranging from 0.1 m³/h to 250+ m³/h. They’re ideal for metering, dosing, and continuous process flows—even when pressure or viscosity changes.

5. Energy Efficient

The progressive cavity mechanism generates less turbulence and reduces mechanical losses. With efficient electric or diesel drives, they require less energy per cubic metre pumped, lowering operating costs.

6. Durability in Harsh Conditions

PC pumps are made to last in extreme environments. MultiTorque supplies pumps with high-wear stators, abrasion-resistant rotors, and heavy-duty seals, keeping them running in high-solids and high-temperature scenarios.

7. Versatile Mounting Options

MultiTorque builds custom progressive cavity pump systems on skids, trailers, or trucks. These mobile pump solutions integrate power generation, hose reels, telemetry, and remote start systems for maximum field flexibility.

Where Are Progressive Cavity Pumps Used?

In Australia, progressive cavity pumps are found in:

• Mining – tailings, paste fill, thickener underflow

• Wastewater – sludge transfer, grit pumping, chemical dosing

• Agriculture – dairy waste, manure, fertigation

• Food & beverage – syrup, juice pulp, wine lees

• Oil & gas – drilling mud, crude oil transport, polymer injection
