Frequently Asked Questions
Q: What seals are included in the HL-SK hydraulic seal kit?
A: The HL-SK contains a full set of piston seals, rod seals, wiper seals, O-rings, and buffer seals. These components work together to maintain hydraulic pressure and prevent internal and external leakage in the pump assembly.
Q: Which pallet jack models does the HL-SK fit?
A: The HL-SK is designed for the Hu-Lift HP25L manual pallet jack hydraulic pump unit. It is an OEM-equivalent seal kit that restores original hydraulic performance. The kit is equivalent to Hu-Lift part number HL 99.
Q: What materials are the seals made from?
A: The HL-SK seals are manufactured from high-grade materials: TPU (thermoplastic polyurethane), NBR (ISO 6195 nitrile rubber), FKM (Viton fluoroelastomer, ASTM D1418), and PTFE (polytetrafluoroethylene). Each material is selected for specific applications within the hydraulic pump to resist pressure, temperature, and chemical exposure.
Q: What is the pressure rating for the HL-SK seal kit?
A: The HL-SK seal kit is rated to match the Hu-Lift HP25L pump specifications, which operate at standard manual pallet jack hydraulic pressures. Consult your jack technical documentation or contact us for exact pressure specifications if needed.
Q: Is the HL-SK equivalent to other seal kit part numbers?
A: Yes. The HL-SK is equivalent to Hu-Lift OEM part number HL 99 and replaces the Hu-Lift HP25L pump seal kit. If your documentation references HL 99 or Hu-Lift HP25L seal kit, the HL-SK is the correct replacement.
Q: When should the HL-SK seal kit be replaced?
A: Replace the HL-SK seal kit when you notice hydraulic fluid leaks around the pump rod, loss of lifting pressure, slow or jerky descent, or if the pump requires frequent topping with hydraulic fluid. These are signs that seals have degraded and can no longer contain pressure.
