Progressive Cavity Pumps
Move your viscous fluids and suspended solids at low velocities with progressive cavity pumps
A rotary progressing or progressive cavity pump is a type of displacement pump usually used for slurry applications. Progressive cavity pumps consist of a screw for continuous flow of viscous fluids and slurries.These pumps get their name because media progresses through cavities created by the stator and rotor, entering the suction side of the pump and flushing out the other side. Here are some tips on choosing a progressing cavity pump:
1. Consider the viscosity and other fluid properties of your application to determine what kind of power and speed you need in a progressive cavity pump.
2. The pumping capacity of progressing cavity pumps is determined not only by the pump dimensions, but by the speed.
3. The stator of a progressing cavity pump usually has waves, the frequency of which will affect the pulsation of the pump. Typically, pulsation for these types of pumps is low.
4. To avoid corrosion, choose progressive cavity pumps in materials that are compatible with your application fluids.
