    Tips: How Does Screw Pump Work?

    A screw pump is a type of positive displacement pump that uses two or more screws (also known as rotors) to move fluid through the pump. The screws rotate, creating a series of voids or cavities between them and the walls of the pump casing. As the screws rotate, these voids move from the suction side of the pump to the discharge side, displacing the fluid and creating flow.
