Frequently Asked Questions
Q: What is the WW PM-12P component used for?
A: The WW PM-12P is a U-cup seal element designed for hydraulic system applications in Dayton manual pallet jacks. U-cup seals create positive pressure-holding barriers within hydraulic cylinders and pump assemblies to prevent fluid bypass and leakage.
Q: Which Dayton pallet jack models accept the WW PM-12P U-cup seal?
A: The WW PM-12P is compatible with Dayton manual pallet jack model 3KR84. Verify your equipment model and hydraulic assembly designation before ordering to ensure proper seal fit.
Q: What material is the WW PM-12P U-cup constructed from?
A: The WW PM-12P is manufactured from elastomer materials formulated to withstand hydraulic fluid exposure, temperature cycling, and pressure conditions typical of manual pallet jack hydraulic systems.
Q: How long does a WW PM-12P U-cup typically last in service?
A: Elastomer U-cup seals typically perform for 3-5 years under normal operating conditions. Lifespan depends on usage frequency, storage temperature, and hydraulic fluid type. Replace sooner if the jack develops slow lift response or inability to hold load.
Q: What indicates that the WW PM-12P U-cup seal requires replacement?
A: Replace the WW PM-12P if the jack leaks hydraulic fluid from cylinder rod areas, slowly descends under load when the control is in neutral, or produces reduced lifting speed. These symptoms indicate U-cup seal degradation or failure.
