Komatsu HPV90 hydraulic pump characteristics
The Komatsu HPV90 hydraulic pump is a powerful and reliable variable displacement axial piston pump, ideal for medium and heavy excavators. Its key advantages are adjustable flow, high pressure resistance, compactness, and wide availability of spare parts.
Technical characteristics of the Komatsu HPV90 hydraulic pump:
- Type: Variable displacement axial piston pump for closed or open circuit (swash-plate, variable displacement)
- Working volume: ≈ 90 ml/rev (90 cm3/rev)
- Nominal pressure: up to 35 MPa (≈350 bar)
- Peak pressure: up to 42 MPa (≈420 bar)
- Rotation speed: nominal – 2500 rpm, maximum – 3000 rpm
- Torque (nominal): ≈ 433 N m
- Power:
- nominal – 128 kW
- peak – 138 kW
- Weight: about 64 kg
- Permissible casing pressure:
- constant – 0.25 MPa (≈2.5 bar)
- peak – 0.5 MPa (≈5.0 bar)
Design features of the Komatsu HPV90 hydraulic pump:
- Swash-plate variable displacement – provides adjustable flow and pressure, increasing system efficiency
- Closed loop – ideal for oil recirculation systems, reduces energy consumption and increases system response
- Compact and robust design – compensates for high operating pressure with relatively small dimensions and weight
- Availability of spare parts – spare parts and repair kits (rotor groups, pistons, valve plates, rods, etc.) are available for the HPV90‑3/5 series
- The pilot gear pump with part number ~704‑24‑28230 weighs approximately 8 kg
