The Gorman-Rupp GHA Series is a heavy-duty rotary gear pump line engineered for continuous operation in abrasive or extreme service conditions. Ideal for pumping challenging or erosive fluids, the GHA Series offers superior wear resistance and long-term durability, even in the toughest environments.
Key features include:
-
Abrasive fluid handling: Built for fluids containing abrasive particles or for applications where wear resistance is critical.
-
Temperature control capability: Equipped with head and backhead jackets to support heating or cooling during operation.
-
Sealing flexibility: Choose from packing seals for simplicity or mechanical seals for improved containment.
-
Robust shaft support: Heavy-duty construction provides enhanced shaft alignment and minimized deflection, especially during continuous use.
-
Maintenance-free bearing design: An integrated radial/thrust bearing requires no lubrication, improving operational uptime.
-
Low-speed performance: Optimized for reduced-speed operation, which lowers wear and supports extended pump service life.
The GHA Series is an extreme-duty pump solution for operations that demand maximum wear protection, thermal control, and reliable continuous service.
