A Progressive Cavity Pumps is a positive displacement pump that uses a rotating screw mechanism to move fluids. The design features one or more screws that turn within a cylindrical housing, drawing fluid in and pushing it out in a continuous flow. These pumps are especially effective for handling viscous fluids, slurries, and materials with solids.
Horizontal screw pumps can self-prime, which allows them to start without being filled with fluid. The flow rate is adjustable by varying the screw speed, making them versatile for different applications. They are typically durable, constructed from materials that can withstand abrasive and corrosive substances.
