Gorman-Rupp Pumps GMS3JJ3-B Positive Displacement Pump

The GMS3JJ3-B Positive Displacement Pump is part of the GMS series designed for medium duty applications. It operates within a capacity range of 3 to 265 GPM (11 to 930 LPM) and can handle pressures up to 150 PSI (10.3 BAR). The pump is suitable for a wide viscosity range, accommodating fluids from 28 SSU to 250,000 SSU (1 to 55,000 cSt), and can operate in temperatures from -60¬8F to 450¬8F (-51¬8C to 230¬8C). This model features high-strength, computer profiled gearing for quiet operation and thrust-controlled pump elements. It offers exceptional seal versatility, with options for carbon graphite or silicon carbide bushings, and various sealing methods including packing and mechanical seals. The GMS3JJ3-B is designed for applications such as booster service, circulating, filtering, lubricating, and transferring fluids. It is a self-contained unit that does not require external bearings unless used in belt-driven configurations, which necessitate a pedestal bearing. Engineers considering this pump should evaluate its specifications against their project requirements, particularly in terms of fluid viscosity, temperature, and pressure needs.
