Frequently Asked Questions
Q: What components are included in the GW 531 hydraulic seal kit?
A: The GW 531 seal kit includes U-cup seals, O-rings, wiper seals, and wear rings. These components are engineered to seal hydraulic pump assemblies in manual pallet jacks against fluid loss and contaminant ingress. The kit is compatible with pump bores up to 1.125 inches and rod diameters of 0.625 inches.
Q: What materials are used in the GW 531 seal kit?
A: The GW 531 seals are constructed from polyurethane (PU), nitrile rubber (NBR), and fluorocarbon rubber (FKM). These elastomeric materials are selected for compatibility with hydraulic fluid and durability under pressure cycling in pallet jack hydraulic systems.
Q: What is the maximum hydraulic pressure the GW 531 handles?
A: The GW 531 is designed to withstand hydraulic pressures up to 3000 PSI. This pressure rating accommodates typical manual pallet jack hydraulic systems used in standard warehouse lifting and load handling applications.
Q: Which pallet jack hydraulic pumps does the GW 531 fit?
A: The GW 531 is compatible with manual pallet jack hydraulic pumps from Crown, Toyota, Raymond, Yale, Hyster, Jungheinrich, Linde, Clark, Mitsubishi, CAT, and BT. Verify pump bore size and rod diameter match the 1.125 inch bore and 0.625 inch rod specifications before installation.
Q: When should the GW 531 seal kit be replaced?
A: Replace the GW 531 when you observe hydraulic fluid leakage from the pump, reduced lifting speed, or inability to maintain pressure. Seal degradation typically occurs after years of service, depending on fluid condition and operating temperature. Regular system maintenance extends seal life.
