Gorman-Rupp GMS Series G Series Medium Duty Positive Displacement Pumps
GMS Series Spec SheetThe GMS Series is designed for intermittent or medium duty service for applications in the operating ranges noted. These units are available with head and backhead jackets for temperature control, carbon graphite bushings for low viscosity liquids, silicon carbide bushings for wear resistance. For continuous duty service, or for handling viscous liquids, see heavy duty GHC pumps.
These cast iron pumps are designed to provide form, fit, and function capabilities as direct drop-in replacements for popular Viking pumps (see chart).
