Frequently Asked Questions
Q: What is the PM P2 back-up ring and where does it go in a manual pallet jack?
A: The PM P2 is a precision back-up ring manufactured from high-density polymer. It is installed in the HSW series manual pallet jack cylinder assembly to provide reliable retention of hydraulic seals under pressure. This component supports the main seal and prevents extrusion into the cylinder clearance gap.
Q: What pressure rating does the PM P2 back-up ring support?
A: The PM P2 is rated for use up to 3000 PSI in manual pallet jack cylinder applications. Verify your equipment system pressure does not exceed this rating before installation.
Q: Which pallet jack models use the PM P2 back-up ring?
A: The PM P2 is compatible with Palletmaster manual pallet jacks, model HSW series. Confirm your equipment model matches before ordering.
Q: What material is the PM P2 back-up ring made from and why?
A: The PM P2 is manufactured from high-density polymer, a material chosen for its strength, compatibility with hydraulic fluids, and resistance to extrusion under high pressure cycles. This material provides long service life in sealed cylinder environments.
Q: Is the PM P2 back-up ring coated or treated?
A: The PM P2 is supplied in raw polymer form with no coating or finish applied. The material itself provides the necessary chemical and pressure resistance required for manual pallet jack service.
