Key Features
- Genuine OEM Construction — Manufactured to original Genie specifications, this seal delivers the material grade and dimensional conformity that a pump sealing application demands.
- Direct OEM Replacement — Engineered to install exactly as the original, this seal drops in without rework or adaptation.
- Broad GTH Telehandler Fitment — Confirmed fitment across the GTH-636, GTH-844, GTH-1056, and GTH-1256, covering a wide range of Genie telescopic handler configurations.
- Maintains Pump Integrity — A sound pump seal prevents fluid loss and keeps the pump operating within its designed parameters; a worn or failed seal can lead to leaks, reduced output, and accelerated wear of surrounding components.
- Trusted OEM Sourcing — Supplied by DHS Equipment as an authorized Genie OEM part, giving you confidence in authenticity and parts traceability.
A pump seal is a critical sealing component that prevents fluid from escaping the pump assembly at its rotating or mating interfaces. When this seal is in good condition, the pump maintains proper pressure and flow, keeping the machine's fluid circuit functioning as designed. When the seal deteriorates or fails, fluid weeps past the sealing surface, leading to visible leaks, pressure drop, and potential damage to the pump and connected components if left unaddressed.
