Frequently Asked Questions
Q: What seals are included in the AT ZMSL-3150 seal kit?
A: The AT ZMSL-3150 is a hydraulic seal kit for Atlas manual pallet jacks containing NBR nitrile rubber seals and Buna-N elastomer O-rings rated to 3000 PSI. The kit includes the single-lip seals and backup rings necessary for complete hydraulic assembly repair.
Q: Which Atlas pallet jack models does the AT ZMSL-3150 fit?
A: The AT ZMSL-3150 is a direct fit for Atlas AA-5 and AA-7 manual pallet jacks and related models in that series. Verify your equipment model nameplate matches before ordering. No cross-reference part numbers are available.
Q: What is the temperature operating range for the AT ZMSL-3150 seals?
A: The AT ZMSL-3150 seals are rated for -20 degrees Fahrenheit to +200 degrees Fahrenheit. This range covers standard warehouse storage, cold storage, and normal operating conditions. Verify your equipment operating environment falls within this range.
Q: What is the pressure rating for the AT ZMSL-3150 seal kit?
A: The AT ZMSL-3150 seal kit is rated to 3000 PSI for high-pressure hydraulic applications. This rating is appropriate for Atlas manual pallet jack hydraulic systems. Do not exceed the specified pressure rating of your equipment.
Q: Why use nitrile rubber seals instead of other elastomer materials?
A: Nitrile rubber NBR offers excellent resistance to mineral oils used in standard hydraulic fluids, good durability in high-cycle applications, and broad temperature range compatibility. The AT ZMSL-3150 specifies nitrile for optimal performance in Atlas hydraulic systems.
Q: How often should the AT ZMSL-3150 seals be replaced?
A: Seal lifespan depends on duty cycle, hydraulic fluid condition, and operating temperature. In heavy-use applications, expect 2 to 3 years of service. Replace seals if you observe hydraulic fluid leakage around cylinder rods or pump connections.
