Komatsu LPD28 hydraulic pump characteristics

The Komatsu LPD28 hydraulic pump is a lightweight (≈10 kg) axial piston variable displacement pump with a capacity of ≈28 cm³/rev, which is a lightweight and powerful solution for mini excavators weighing 5–7 tons. It withstands pressures up to 350–420 bar, has a reliable design, and is supported by a wide range of spare parts.

Technical characteristics of the Komatsu LPD28 hydraulic pump:

• Type: Variable displacement axial piston pump
• Displacement: approx. 28 cm³/rev.
• Pressure:
  • Nominal: up to 35 MPa (350 bar)
  • Peak: up to ≈ 42 MPa (420 bar)
• Rotational speed: approximately 2000–3000 rpm - typical for mini excavators, although exact data requires service documentation.
• Weight: about 10 kg
• Materials: cast iron body, rotor/plungers - steel/bronze
