Frequently Asked Questions
Q: What equipment does the LF 20280 seal kit fit?
A: The LF 20280 is a complete seal kit for Lift-Rite manual pallet jack hydraulic pumps. It fits Lift-Rite and LR2055 series models with bore diameters up to 1.125 inches and pump rod diameters of 1.00 inch. Cross-reference part numbers include LR20280, Lift-Rite 20280, PL-20280, and LF PL-20280.
Q: What are the seal specifications for the LF 20280?
A: The LF 20280 contains nitrile rubber seals with double-lip, pressure-energized design manufactured to Lift-Rite specifications. Seals are rated for standard working pressures up to 3000 PSI and are designed for hydraulic pump applications requiring reliable fluid containment.
Q: Does the LF 20280 have equivalent or superseded part numbers?
A: Yes. The LF 20280 supersedes part numbers 20278 and 20279. Equivalent part numbers include PL20280 and LF PH-20280. All cross-references represent direct interchangeable replacements for Lift-Rite hydraulic pump applications.
Q: What is the typical lifespan of the LF 20280 seal kit?
A: Nitrile rubber seals like those in the LF 20280 typically maintain effectiveness for 3-5 years under normal operating conditions. Lifespan depends on operating temperature, pressure cycles, and maintenance practices. Inspect seals annually and replace if you observe fluid leakage, degradation, or hardening of rubber components.
Q: How should I maintain the LF 20280 hydraulic seals?
A: Monitor pump performance for signs of internal leakage, such as slow lifting or inability to hold load. Maintain hydraulic fluid cleanliness and ensure proper fluid levels. Check pump temperature regularly, as excessive heat accelerates seal degradation. If leakage occurs, the seal kit requires replacement. Do not attempt repairs to individual seal components.
