What are Progressive Cavity Pumps?
Progressive cavity pumps are versatile tools suitable for multiple different applications in different industries. Also known as progressing cavity pumps, they are type of positive displacement pump, designed to handle high-viscous fluids and tough pumping applications, commonly used in fluid metering and pumping of viscous or shear-sensitive materials. They are particularly effective in applications where the fluid viscosity is beyond the efficient range of centrifugal pumps.
How do Progressive Cavity Pumps work?
A progressive cavity pump works by using a helical rotor that rotates inside a double-helix stator. The rotor forms a set of fixed-size cavities that move as the rotor turns, transferring fluid through the pump. This design results in a flow with minimal pulsation and low levels of shearing applied to the pumped fluid. The rotor, typically made of solid metal, rotating inside a stator, usually made from an elastomeric material like natural rubber creates cavities that progress along the length of the pump, moving the fluid from the inlet to the outlet. This mechanism allows the pump to handle high-viscous fluids and tough pumping applications effectively.
