Screw Pump

A screw pump is a type of positive displacement pump that uses one or more screws or helical rotors to move fluid or gas along the pump's axis. The pump consists of a helical screw or rotor that rotates inside a cylindrical or semi-cylindrical cavity. As the screw rotates, it traps and moves fluid or gas along the length of the screw and through the pump, from the inlet to the outlet. The screw and the cavity walls form a series of chambers, which progressively reduce in size along the length of the pump, causing the fluid or gas to be compressed and pressurized. Single screw pump in the range is commonly used in the oil and gas industry, wastewater treatment plants, food processing facilities, and other industries.
