Product Description
The Wesco WE A325 is a polyurethane U-cup seal engineered as a primary sealing element for hydraulic pump assemblies in Wesco CPI series manual pallet jacks. This high-wear compound seal prevents hydraulic fluid loss during pump cycling and lift operations, ensuring consistent performance and longer equipment life. Designed for compatibility and durability, the WE A325 tolerates cyclic pressure loading and repeated compression-relaxation cycles inherent to manual pallet jack duty. It serves as a direct replacement component for Wesco CPI hydraulic systems where reliability is essential for smooth load handling.

Frequently Asked Questions
Q: What does the WE A325 U-cup seal do in a Wesco CPI pallet jack hydraulic system?
A: The WE A325 is a polyurethane U-cup seal that functions as the primary sealing element within the hydraulic pump assembly of Wesco CPI manual pallet jacks. It seals the pump rod and housing interface to prevent hydraulic fluid loss during pump cycling.
Q: What is the material composition of the WE A325?
A: The WE A325 is manufactured from polyurethane high-wear compound. This material is selected for its ability to withstand cyclic pressure loading, resistance to hydraulic fluids, and durability in manual pallet jack duty cycles. Polyurethane seals tolerate the repeated compression and relaxation that occurs during load lifting and lowering.
Q: How long does the WE A325 U-cup seal typically last?
A: Seal lifespan depends on usage frequency, operating temperature, hydraulic fluid condition, and storage conditions. Under moderate to heavy use, U-cup seals typically remain functional for 2 to 5 years or longer. Regular maintenance, keeping the hydraulic fluid clean, and protecting the jack from extreme temperatures extend seal life.
Q: What symptoms indicate that the WE A325 seal needs replacement?
A: Replace the WE A325 if you observe hydraulic fluid leaking from the pump during or after lifting, if the jack loses pressure over time, or if the pump becomes difficult to operate. These are signs that the seal has lost its effectiveness and is allowing internal fluid bypass.
Q: Are there cross-reference or equivalent parts for the WE A325?
A: No published cross-reference, supersession, or equivalent part numbers from other manufacturers are available for the WE A325. This is a Wesco-specific OEM component designed exclusively for CPI series equipment. Verify your equipment model before ordering.
