Frequently Asked Questions
Q: What is the PR 11039-13 seal and what is its pressure rating?
A: The PR 11039-13 is an OEM oil seal designed for manual pallet jack hydraulic pump applications. It is constructed from HNBR material and is rated to 3,000 PSI, making it suitable for standard mineral hydraulic systems operating at typical pallet jack pressure levels.
Q: Which manual pallet jacks use the PR 11039-13 seal?
A: The PR 11039-13 is compatible with Prime Mover and BT Prime Mover manual pallet jack hydraulic pump assemblies. Cross-reference numbers include PM11039-13 and PR11039-13. Verify the pump housing bore and shaft diameters match before ordering.
Q: What hydraulic fluid is compatible with the PR 11039-13 seal?
A: The PR 11039-13 seal is compatible with mineral hydraulic oils ISO VG 32 through ISO VG 46. Do not use synthetic fluids or non-mineral oils unless your manual pallet jack manufacturer specifically approves them, as material compatibility may be compromised.
Q: What is the radial clearance requirement for PR 11039-13 installation?
A: The PR 11039-13 requires 0.010 inch radial clearance between the seal outer diameter and the pump housing. Inadequate clearance can cause binding or damage to the seal. Verify housing bore diameter is within tolerance before installation.
Q: What causes premature failure of the PR 11039-13 seal?
A: HNBR seals fail prematurely from contamination in hydraulic oil, incorrect installation clearance, wrong fluid type, or over-pressure conditions exceeding 3,000 PSI. Maintain clean fluid through proper filtration and monitor system pressure regularly to extend seal life.
Q: Is the PR 11039-13 a rotary shaft or stationary seal?
A: The PR 11039-13 is designed for pump assembly duty. Confirm whether it seals a rotating shaft or stationary housing interface by reviewing your manual pallet jack hydraulic pump assembly diagram before installation.
