Progressive cavity pumps are positive displacement pumps featuring a spiral, helical rotor. These pumps deliver a continuous, low-pulsation flow and can handle high-viscosity and temperature-sensitive materials with minimal shear and almost no pulsation. They are cost-effective, require minimal maintenance, and can be used both for precise dosing and for transferring liquids over long distances. Thanks to their low shear and pulsation characteristics, they are ideal for handling liquids containing solid particles or those requiring gentle treatment. AxFlow offers pumps and support for a wide range of industries and applications.

How do progressive cavity pumps work?
Progressive cavity pumps, also known as PC pumps, eccentric screw pumps, or helical rotor pumps, are a type of positive displacement pump. A helical screw-like rotor, resembling a wine opener, is housed inside a stator and rotates to form cavities through which the fluid flows. These cavities have a defined volume, determining the pump’s volumetric flow, which is directly related to the rotor speed. This movement causes slight deformation and virtually no pulsation. Pumping speed generally depends on pump size and the fluid being pumped. Larger pumps typically operate at lower rotational speeds, while smaller ones run faster. Pump speed can be adjusted using a gearbox or a rubber V-belt between the pump and the motor.
Advantages of progressive cavity pumps
- Efficiency and maintenance: Progressive cavity pumps are known for their durability and minimal maintenance needs. Their design enables on-site maintenance, making them a cost-effective solution for fluids with high viscosity or sensitivity to temperature.
- Flow characteristics: These pumps ensure a smooth, low-pulsation flow, making them ideal for dosing and transferring fluids containing delicate solid particles. The gentle pumping action helps prevent material damage.
- Pressure handling: Thanks to their ability to generate high pressures, PC pumps are excellent for transporting fluids over long distances, reducing the need for additional pump stages.
- Handling complex fluids: Their low internal speed and high-pressure capability make progressive cavity pumps suitable for transferring viscous, abrasive, or temperature-sensitive fluids while minimizing system wear.
- Applications: Progressive cavity pumps are commonly used where gentle material handling is crucial – in the food, beverage, cosmetics, and chemical industries, as well as in wastewater treatment and dosing systems.
