Progressive Cavity Pumps
Progressive cavity pumps, also known as PC pumps, utilize a helix-shaped rotor and a flexible stator to dose or transfer liquids in a system. The rotor turns within and against the walls of the stator to create sealed pockets of liquid moving the contents through the pump. Motor-driven progressive cavity pumps include a motor. Pedestal-mount progressive cavity pumps do not include a motor. They are belt driven or operated by a motor via a coupler. Repair parts for progressive cavity pumps replace commonly-worn components and keep pumps in good working order.
