Frequently Asked Questions
Q: What seals are included in the polyurethane seal kit SKU 800037860?
A: This kit contains piston seals, wiper seals, and O-ring seals made from polyurethane (PU) material. All seals are designed to restore hydraulic integrity and prevent fluid leaks in manual pallet jack pump assemblies.
Q: What PSI rating does this seal kit support?
A: SKU 800037860 is rated for hydraulic pressure up to 3000 PSI under typical manual pallet jack operating conditions. This rating accommodates standard manual lifting cycles in warehouse and logistics environments.
Q: Which manual pallet jack models and manufacturers use this seal kit?
A: This seal kit is compatible with industry-standard manual pallet jack hydraulic pump systems from Crown, Toyota, Yale, Raymond, Hyster, and other major OEM manufacturers. Verify your pump head dimensions and seal bore sizes before ordering.
Q: How do I know when to replace the hydraulic seals?
A: Replace seals if the jack is leaking hydraulic fluid around the pump rod, refuses to hold pressure, or gradually loses lifting height after repair. Worn seals cannot maintain pressure and will cause performance degradation.
Q: Does this kit work in cold storage or wet environments?
A: Yes. Polyurethane seals function reliably in cold storage and wet conditions typical of modern warehouses. Confirm that your pump operates within the specified temperature range and inspect seals periodically for degradation in harsh environments.
