What Is a Progressing Cavity Pump?
A progressing cavity pump is a type of pump that operates by the expansion and contraction of a helical shaft, pushing out liquid.
The rotation of the helical shaft causes a piston to move back and forth, thereby drawing in and discharging liquid. This pump, characterized by its compact and lightweight design, as well as its simple structure and easy maintenance, finds applications in various fields such as industrial machinery, medical equipment, food processing, and transportation.
The basic mechanism consists of the helical shaft, piston, suction side, and discharge side. The movement of the piston is driven by the expansion and contraction of the helical shaft, which is the mechanism for pushing out the liquid. The features of the progressing cavity pump include its small size, lightweight, simple structure, and easy maintenance. These qualities make it versatile for use in different industries and applications, particularly as a small-sized pump.
