Frequently Asked Questions
Q: Is GW 525 equivalent to GW 525-A or GP525-A?
A: GW 525, GW 525-A, and GP525-A are equivalent seal kits with identical internal components and performance specifications. All three part numbers reference the same O-rings, U-cup seals, backup rings, and bushings. When ordering replacement seals for manual pallet jack pump assemblies, you can use any of these three part numbers interchangeably without concern for compatibility or fit.
Q: What does the GW 525 seal kit contain?
A: GW 525 is a complete internal service kit containing all critical seals and components needed to rebuild a manual pallet jack pump assembly. The kit includes O-rings, U-cup seals, backup rings, and bushings. Materials are NBR (nitrile rubber) and urethane formulated to meet OEM performance standards. This is a full overhaul kit, not a partial seal replacement.
Q: How do I know if GW 525 is the correct kit for my pump assembly?
A: Locate the pump assembly part number or manufacturer name on your pallet jack. If your pump is labeled GW 525, GW 525-A, or GP525-A, or if your OEM documentation references any of these part numbers, then GW 525 is the correct kit. If you cannot find a part number, contact the jack manufacturer or distributor with your jack model and serial number to confirm pump specification.
Q: What is the pressure rating of GW 525, and how often should seals be replaced?
A: GW 525 is rated for manual pallet jack hydraulic units operating up to 3000 PSI. Seal replacement interval depends on usage and maintenance. For heavy-use jacks (daily operation), plan a complete overhaul every 2 to 3 years. For light use (occasional operation), seals can last 5+ years. If you notice reduced lifting pressure, slow descent, or oil leaks from the pump body, replace seals immediately regardless of age.
Q: Can I order GW 525-A or GP525-A if GW 525 is on backorder?
A: Yes. GW 525-A and GP525-A are direct equivalents to GW 525 and will function identically in your pump assembly. There is no performance difference or compatibility issue between the three part numbers. If your supplier cannot fulfill GW 525, request either alternate part number without delay.
