Komatsu HPD56 hydraulic motor characteristics
The Komatsu HPD56 hydraulic motor is a powerful axial piston motor with a variable displacement (~56 cm3/rev section), a nominal pressure of up to 400 bar and a rotational speed of up to ~3200 rpm. It is used in a series of medium-heavy Komatsu excavators, and weighs about 170 kg when assembled.
Technical characteristics of the Komatsu HPD56 hydraulic motor:
- Type: variable displacement axial piston hydraulic motor
- Volume: the HPD56 rotor group kit corresponds to approximately half of the tandem configuration (≈ 56 cm3/rev of one section), a total of 112 cm3/rev in the 56+56 variant.
- Pressure:
- Maximum operating pressure: up to 40 MPa (~400 bar)
- Nominal: 35–42 MPa (350–420 bar)
- Rotation speed: up to ~3,200 rpm
- Weight: approximately 170 kg
