A progressive cavity pump is a powerful piece of equipment to move viscous materials with ease. Unlike centrifugal pumps, which push minimal amounts of fluid with extensive power, these devices use minimal power to push a material as it grows thicker. They’re far more capable of handling thick fluids, preventing issues like overuse and possible power failure. Here’s what you should know about them.

How Do Progressive Cavity Pumps Work?

A progressive cavity pump functions by relying on positive displacement. It features a metallic rotor set within a rubber case, known as a stator. Within the case are miniscule cavities that hold the viscous material as it flows. When the rotor moves, the material is transferred from one side of the device to the other.

This happens progressively, as one cavity fills up with material before emptying into another one. This allows the material to displace at a uniform pace, preventing issues, like overflow or fluctuations in flow rates.  

What Industries Use Them & What Are the Benefits? 

This level of accuracy makes this pump an essential component in a variety of industries. Their versatility is perfect for transporting anything from yogurt to chemicals or petroleum expertly. They are widely used in recycling plants to transfer the pulpy remains of paper and in anaerobic facilities where wastewater is treated.

The device works at a fixed volume with each turn of the rotor, ensuring the product amount doesn’t change. Even if another variable is altered, like the temperature or the pressure of the fluid, it won’t impact the displacement process. Because the process is so streamlined, it also has a positive impact on business productivity, which can benefit the bottom line in the process. It’s also a quiet machine, so its operation will not cause disruptions.
