Frequently Asked Questions
Q: What is the HL 146 Piston and what does it do?
A: The HL 146 Piston is a precision-fit component in the Hu-Lift HP25L pump that seals the pump chamber and transfers hydraulic pressure to lift the load. It moves up and down to create the pumping action.
Q: Which pallet jack models require the HL 146 Piston?
A: The HL 146 Piston is designed for Hu-Lift HP25L manual pallet jacks. Check your equipment documentation to confirm your model requires this specific piston before ordering.
Q: What are the signs that the HL 146 Piston is failing?
A: Replace the HL 146 if the pump produces no pressure, the handle moves freely with no resistance, hydraulic fluid leaks from the pump, or the pallet jack cannot raise loads. A damaged piston breaks the seal needed for pressure buildup.
Q: Is the HL 146 Piston a wear item?
A: Yes, the HL 146 is a wear item. Repeated cycling creates friction between the piston and pump walls. Contaminated hydraulic fluid accelerates wear. High-frequency use shortens service life to 2 to 4 years.
Q: What material is the HL 146 Piston made from?
A: The HL 146 Piston is hardened steel with a precision ground surface for optimal sealing against the pump cylinder. The surface finish is critical for maintaining hydraulic pressure.
