PUMP PACKING
Frequently Asked Questions
Q: What is the LJ 17-A PUMP PACKING and what does it do?
A: The LJ 17-A PUMP PACKING is a sealing component used in Lo-Jo pallet jack hydraulic pumps. Pump packing prevents hydraulic fluid leakage around the pump shaft where it enters the pump housing, maintaining system pressure.
Q: What material composition is the LJ 17-A made from?
A: Pump packing is typically manufactured from braided or wrapped synthetic fibers with elastomer binders, designed to withstand continuous shaft rotation and exposure to hydraulic fluid without degradation.
Q: How long does pump packing last in typical pallet jack service?
A: Pump packing lifespan varies based on usage frequency and maintenance. In regular industrial use, packing typically lasts 2 to 5 years before requiring replacement. Heavy use or contaminated fluid reduces service life.
Q: What are signs that the LJ 17-A pump packing needs replacement?
A: Visible dripping or weeping of hydraulic fluid at the pump shaft, persistent oil spots on the pump housing, loss of pressure during operation, or inability to maintain load all indicate pump packing failure.
Q: Can contaminated hydraulic fluid damage pump packing?
A: Yes. Water, dirt, or sludge in hydraulic fluid can degrade pump packing material and cause premature failure. Maintaining clean hydraulic fluid with regular filter changes significantly extends packing life.
