G Series Rotary Gear Pumps

The Gorman-Rupp G Series Rotary Gear Pump is a positive displacement pump engineered to deliver stable performance, high efficiency, and long-term reliability across a wide range of industrial applications. Featuring a robust construction, optimized shaft support, and ball bearing–based thrust control system, this pump is capable of operating under high pressures, extreme temperatures, and a broad viscosity range.

Designed for ease of installation and maintenance, the G Series incorporates externally adjustable rotor clearance and a back pull-out design, allowing servicing without disconnecting the piping system. Flexible sealing options and various material configurations make this pump suitable for handling non-corrosive, corrosive, and abrasive fluids.

Features:

• Externally adjustable rotor clearance and ball bearing thrust control for enhanced stability and extended service life
• Deep end feed design for high efficiency across low to extremely high viscosity fluids
• Flexible sealing system and back pull-out design for simplified maintenance
