Frequently Asked Questions
Q: What does the EC PAL-PRK-U hydraulic seal kit include?
A: The EC PAL-PRK-U is a complete Ecoa hydraulic seal kit containing U-cup seals, O-rings, and wiper components. It is designed for PAL and PLH manual pallet jack pump units and covers all critical sealing surfaces in the pump bore and rod areas.
Q: What material are the seals in EC PAL-PRK-U made from?
A: The EC PAL-PRK-U seal kit uses NBR (nitrile rubber) and polyurethane components. These materials provide chemical resistance to ISO hydraulic oils and are rated for standard warehouse operating temperatures and manual duty cycles.
Q: Which Ecoa pallet jack models are compatible with EC PAL-PRK-U?
A: The EC PAL-PRK-U is designed for Ecoa PAL model pallet jacks and PLH electric models. It also cross-references as ECPAL-PRK-U and PAL-PRK-U. Verify your pump bore and rod dimensions match standard Ecoa specifications before ordering.
Q: What is the service life of seals in this kit under normal use?
A: Under typical manual pallet jack duty (approximately 120 cycles per hour), hydraulic seals typically last 2-4 years before wear requires replacement. Lifespan depends on oil cleanliness, temperature, and load profile. Replace the entire kit if internal leakage is detected.
Q: What symptoms indicate the pump seals in EC PAL-PRK-U need replacement?
A: Symptoms include external oil weeping from the pump rod area, spongy handle feel, loss of lifting height, or inability to maintain pressure. Internal seal wear shows as reduced pump output or handle that becomes difficult to operate through the full stroke.
