HPD

Main advantages and scope of application of Komatsu HPD series hydraulic motors

Komatsu HPD series hydraulic motors are axial piston motors with adjustable displacement, designed to drive the main mechanisms in construction and quarrying equipment. Thanks to the design with a swash plate, they provide high power, reliability and efficient operation under high load conditions. HPD hydraulic motors are ideal for use in track drives, slewing systems and other important components of Komatsu equipment.

The main advantages of Komatsu HPD hydraulic motors:

1. High power and torque – HPD hydraulic motors provide stable and powerful torque transmission, which is important for heavy equipment.
2. Adjustable volume – thanks to the swashplate design, the motor can adapt to load changes, increasing the energy efficiency of the system.
3. Reliability in difficult conditions – designed for long-term operation at high pressures (up to 350–400 bar) and under heavy load conditions.
4. Compact and robust design – optimal weight and dimensions simplify installation and maintenance.
5. Low noise and vibration levels – modern design reduces mechanical vibrations, which increases operator comfort and reduces component wear.
6. Compatibility with Komatsu equipment – are ideally integrated into the drives of tracked undercarriages, slewing mechanisms, etc.
7. Ease of maintenance – modular design and availability of spare parts simplify diagnostics and repairs.

These advantages make HPD hydraulic motors a reliable choice for heavy construction and quarrying equipment where durability and high performance are required.
