JRR Series Hydraulic Pump Replacement JRR075 JRR060 JRR045 OVERVIEW

Features and Benefits

• Perfect Interchangeability

  Fully consistent with original mounting flange, shaft splines, port layout and control interface. No modification is needed during replacement.
• Energy-saving Load Sensing Control

  LS load-sensitive structure automatically adjusts displacement. It reduces unnecessary power consumption and lowers system heat generation under partial load.
• Heavy-duty High Pressure Design

  Reinforced cylinder block, pistons and bearing components. Continuous working pressure reaches 310 bar, peak pressure up to 400 bar, suitable for long-term harsh construction site operation.
• High Volumetric Efficiency

  Precision ground friction pairs keep volumetric efficiency above 95%. Low internal leakage ensures steady flow output under continuous high pressure.
• Modular Easy Maintenance

  Integrated compact structure. Core spare parts such as pump core, valve plate and pistons are universal, greatly shortening downtime for overhaul.

HPV055 HPV075 High Pressure Piston Pump FAQ:

1. What is the HPV055 HPV075 High Pressure Piston Pump ?

• It adopts swashplate axial piston structure with heavy-duty cast iron housing, supporting stable high-pressure operation with low internal leakage.

• It has load-independent control, including mechanical, hydraulic and electro-hydraulic proportional options, with fast response and accurate flow regulation.

• Built-in charge pump, high-pressure relief valves and replaceable filter ensure reliable protection for closed-loop hydrostatic systems.

• Compact layout and high power density make it fit well on harvesters, road rollers and crawler loaders.

• Identical mounting dimensions allow direct replacement of original Linde pumps without system modification.
  
  

3. What is the working pressure range of HPV055 HPV075 High Pressure Piston Pump ?

• Continuous rated working pressure: 420 bar (6090 PSI)

• Peak transient pressure: 480 bar (6960 PSI)

• Charge pump loop pressure: 20 ~ 30 bar (290 ~ 435 PSI)

4. Can HPV055 HPV075 High Pressure Piston Pump replace other brands?

• We recommend ISO VG 46 anti-wear hydraulic oil (L-HM46) for HPV055 and HPV075 piston pumps, which meets the requirements of closed-loop high-pressure hydrostatic systems.

• Operating viscosity range: 10 ~ 160 mm²/s; the optimal working viscosity is 30 mm²/s at operating temperature.

• The oil must contain anti-wear, anti-rust, anti-oxidation, anti-foam and air release additives. Water-glycol fluids are not allowed.

• System oil cleanliness should reach ISO 18/16/13 with a 10-micron return filter to extend pump service life.

6. What is the typical speed range of HPV055 HPV075 High Pressure Piston Pump ?

• HPV055:Continuous operating speed: up to 3500 rpmMaximum intermittent speed: 3900 rpmMinimum stable working speed: 500 rpm

• HPV075:Continuous operating speed: up to 3200 rpmMaximum intermittent speed: 3400 rpmMinimum stable working speed: 500 rpm

• Recommended economic working range: 1800 ~ 2600 rpm for long service life.
