Rotary Gear Pumps

All Gorman-Rupp G Series pumps are designed with numerous features that you'll find on no other gear pumps, allowing them to outlast and outperform the competition.

1. Wear Resistant Rotor &Idler
Hard, austempered ductile iron gears are designed to resist abrasion. Computer-designed gear tooth profile provides smooth, quiet pumping flow.

2. Carbide Idler Pin/Idler Bushing
Carbide idler pin/idler bushing set provides extreme wear resistance under the most severe abrasive applications.

3. Exclusive Seal Cavity Design
State of the art mechanical seal sits in a tapered seal bore design to extend seal life by directing abrasives away from the seal faces and out of the pump.

4. Wear Resistant Pump Head &
    Housing.

Critical wear areas of both the pump head and housing are hardened to resist wear and maintain maximum pump efficiency.

5. Needle Bearing Shaft Support
Needle bearing provides exceptionally reliable high-load shaft support and better rotor shaft stability, which extends seal life and operational life of the pump.

6. Hard Face Mechanical Seal
Silicon carbide seal faces mounted in a highly engineered mechanical seal, ensure maximum life and reliability with minimum wear.

7. Easy Motor Center Height
    Adjustment

Foot Brackets are centrally located under pump ports, providing better pump and piping support. Multiple center line heights allow simple and inexpensive bases.

8. Simple and Precise Rotor Adjustment
Simple, rugged, double-piloted design provides easy and precise rotor adjustment. Sealed double row bearings are maintenance free.

9. Back Pull-Out Design for easy
    Service

Unique back pull-out design allows service and maintenance without disconnecting pump housing from piping.
