Frequently asked
Can this spring be used as a direct replacement for OEM valve return springs?
Yes, it is engineered as a direct replacement for worn valve return springs in standard hydraulic pump assemblies.
Does this compression spring support both 550 mm and 685 mm fork frames?
It is designed to maintain stable actuation and fits both 550 mm and 685 mm frame configurations.
Will this spring work with 2.5 ton capacity trucks?
It is rated for 2 ton, 2.5 ton, and 3 ton load capacity compatibility across compatible hydraulic systems.
How does high carbon spring steel improve pump performance?
The material delivers high tensile strength and fatigue resistance, ensuring consistent valve return and pump pressure.
More questions buyers ask
What is the function of a hydraulic jack spring in a pallet truck?
The spring ensures the valve returns to its closed position, allowing the hydraulic pump to build pressure for lifting.
Is this spring compatible with all hand pallet truck brands?
It is designed as a universal-fit replacement for standard hydraulic pump assemblies used in most 2T to 3T hand pallet trucks.
What material is the Pentagon pallet jack spring made of?
It is manufactured from high-grade high carbon spring steel for maximum fatigue resistance and durability.
How do I know if my pallet truck spring needs replacement?
If your pallet truck fails to hold pressure, lifts slowly, or the handle feels 'spongy', the valve return spring may be fatigued.
Does this spring fit both 550mm and 685mm fork widths?
Yes, the spring is compatible with the hydraulic pump assemblies used in both standard 550mm and wide 685mm fork configurations.
Can I install this spring myself?
Yes, it is a standard maintenance part, though it requires basic knowledge of hydraulic pump disassembly and reassembly.
What is the load capacity compatibility for this spring?
This compression spring is engineered for use in 2 Ton, 2.5 Ton, and 3 Ton capacity hydraulic hand pallet trucks.
Does the spring come with a warranty?
Pentagon provides standard industrial quality assurance. Please check your invoice for specific warranty terms.
How often should I replace the hydraulic pump spring?
Replacement is typically required during major pump overhauls or when signs of hydraulic pressure loss appear.
Is GST invoice provided with the purchase?
Yes, all purchases include a valid GST invoice for business accounting purposes.
Who should choose the Pentagon Hydraulic Jack Spring?
Maintenance managers and warehouse technicians looking for a reliable, high-fatigue-resistant replacement spring for their pallet truck fleet.
How does this spring compare to generic low-cost springs?
Unlike generic springs, this Pentagon unit uses high carbon steel to prevent permanent deformation and ensure consistent pump pressure over thousands of cycles.
