The Progressive Cavity Pump is an extremely versatile pump that can be used in many different pumping applications. It offers all the advantages of a positive displacement pump and is specially designed for abrasion resistance in tough pumping applications.
The progressive cavity pump is a positive displacement pump. This is different than the more commonly used centrifugal pump. A centrifugal pump is a good, economical choice when pumping water like fluids with low viscosity and when a fixed flow and constant discharge pressure are the basis of the application. A well-applied centrifugal pump will offer years of reliable service in simple pumping applications.
A progressive cavity pump is used when the pumping application is not suited to a centrifugal pump. One of the clearest examples of when to use a progressive cavity pump is when the liquid has a higher viscosity, or thickness, than water. Centrifugal pumps become very mechanical and volumetrically inefficient when the viscosity of the liquid goes up, meaning the flow goes down and the power consumption goes up. The opposite occurs with a progressive cavity pump, the mechanical efficiency and volumetric efficiency goes up when the viscosity increases, lower power and more flow.
A progressive cavity pump is therefore ideal for liquids with higher viscosities. In addition a progressive cavity pump will have about the same flow no matter what the viscosity of the liquid is. If you have a pumping application where you need a constant flow, but the liquid viscosity is variable and will change, then the PC pump is an ideal choice.
