The SEIM PWOF series screw pump is a positive displacement, self-priming pumps suited to handle various oils and other fluids with minimum lubricating properties. They are also used for pumping water-based coolants for machine tool and lubrication systems. The three rotor screw pump design makes them intrinsically reliable and efficient in their applications.

The SEIM PWOF three rotor screw pump series is designed to work with viscosities as low as 1.2 cSt in high pressure pumping applications. It’s self-priming capability and low noise level allows continuous duty at 2175 PSI (150 bar).

The PWOF series inlet port is available in axial configurations (vertically or horizontally), with added connection adapters or strainers upon request. The PWOF series operates from 3.7 to 450 GPM, at pressures up to 2175 PSI, with temperature range of 32 °F to 212 °F. For applications such as mining, machine tool, hydropower, lubrication and automobile, the PWOF pump is preferred due to its low noise levels, efficiency and reliability. It’s aluminum casing makes it lighter weight and spark resistant. The PWOF has a compact design with hardened screws that is used in submersible or out of tank arrangements. We supply complete PWOF pump units with motors upon request. Contact a Shanley Pump and Equipment representative today.
