Komatsu HPV132 hydraulic pump specifications

The Komatsu HPV132 hydraulic pump is a variable displacement axial piston pump of the swash plate type, designed for use in medium and heavy-duty excavators, in particular the PC300 and PC350 series. It provides high performance, pressure resistance up to 420 bar and reliable operation under heavy load conditions. Thanks to the tandem design (HPV132+132), the pump combines power and compactness, making it an effective solution for hydraulic systems with variable operating modes.

Technical characteristics of the Komatsu HPV132 hydraulic pump:

• Type: Variable displacement axial piston pump (Swash plate type)
• Design: Double (tandem) pump - two sections of 132 cm³/rev (in HPV132+132 configuration)
• Displacement: ~132 cm³/rev for one section
• Nominal pressure: up to 35 MPa (350 bar)
• Maximum pressure: up to 42 MPa (420 bar)
• Rated rotation speed: ~2200–2500 rpm
• Maximum rotation speed: up to 2800–3000 rpm
• Shaft power: approximately 140–180 kW (depending on mode)
• Weight: ~180–220 kg

Design features of the Komatsu HPV132 hydraulic pump:

• The design allows smooth adjustment of the oil supply depending on the load
• Possibility of using electro-hydraulic or mechanical regulator
• Good maintainability: there is a wide selection of spare parts (plungers, cylinder blocks, oil seals)
• Compactness in its power category
