Expert Guide to Maintaining Hydraulic Pumps: The Beating Heart of HARDEX Equipment

Hydraulic pumps in equipment such as pallet jacks and stackers are subjected to the highest operational pressure. HARDEX premium products utilize imported pumps with a Dual-Sealing system, but even the world’s best pumps require proper care to prevent premature wear and tear.

Crucial Steps to Extend Pallet Jack Pump Lifespan

Checking Hydraulic Oil Level and Quality:

Using non-standard oils causes O-ring corrosion. Always use hydraulic oil with the standard viscosity.

Proper Air Bleeding of the System:

If your pallet jack does not lift the load completely or moves in steps, air has likely entered the system. (In this section, you can explain the steps for opening the bleed screw).

Preventing Overload:

HARDEX pumps are equipped with safety valves, but repeated overloading puts destructive pressure on the oil seals.

Engineering Difference Between HARDEX AC Pumps and Conventional Pumps

Unlike pressed pumps, where the entire unit must be replaced if damaged, HARDEX pumps are serviceable. This means that if needed, the pump can be restored to its original condition by simply replacing a small component, representing significant long-term cost savings.
