Frequently Asked Questions
Q: What type of seal is the BO 60109 and where does it function in a pallet jack?
A: The BO 60109 is a molded nitrile rubber wiper seal designed for the hydraulic piston rod of Boman manual pallet jack pump assemblies. It serves as an exclusion seal to prevent external contamination from entering the pump chamber while the piston rod moves during lift cycles.
Q: What is the Shore A hardness rating of the BO 60109 wiper seal?
A: The BO 60109 wiper seal has a hardness specification of 70 Shore A ±5. This durometer provides the correct balance of flexibility for dynamic rod sealing while maintaining tear resistance and long-term dimensional stability.
Q: Which Boman pallet jack models require the BO 60109 wiper seal?
A: The BO 60109 wiper seal is a direct replacement for Boman model 60109 manual pallet jack hydraulic pump assemblies. There are no published cross-reference part numbers available for other manufacturers, so confirm your exact Boman model before ordering.
Q: Why is the BO 60109 seal critical for pump performance?
A: The BO 60109 wiper seal excludes dirt, moisture, and particulate from contaminating the internal hydraulic oil. Without effective sealing, abrasive particles will accelerate wear on the piston rod, pump body, and sealing surfaces, leading to internal leakage and complete pump failure.
Q: What environmental conditions affect the lifespan of the BO 60109 nitrile rubber seal?
A: Nitrile rubber seals like the BO 60109 degrade faster in extreme heat, ozone exposure, and wet environments. Cold storage or outdoor loading dock use will extend seal life, while high-temperature warehouses or UV exposure will reduce durability. Standard warehouse temperatures support 3 to 5 years of typical service life.
Q: What signs indicate the BO 60109 wiper seal is failing?
A: Symptoms of seal failure include visible oil leakage at the pump rod entry point, milky or contaminated hydraulic fluid, reduced pump efficiency or erratic lift speed, or visible dirt accumulation around the piston rod. Prompt replacement prevents secondary damage to internal pump components.
