What Is a Three Screw Pump?
A three screw pump is a type of rotary positive displacement pump that uses three intermeshing screws to move fluid smoothly and efficiently. Often used for high-pressure, high-viscosity applications, IMO’s screw pumps are ideal for lubrication, fuel transfer, and hydraulic systems, delivering quiet, pulse-free flow and long-term reliability.
