Main advantages and scope of application of Komatsu HPV series hydraulic pumps
Komatsu HPV series hydraulic pumps are axial piston variable displacement swash plate pumps designed for use in the main hydraulic systems of Komatsu excavators. They provide precise adjustment of the working fluid supply according to the load, which increases the efficiency and cost-effectiveness of the machine. HPV pumps are characterized by high reliability, durability and optimal performance in difficult operating conditions.
The main advantages of Komatsu HPV series hydraulic pumps:
- High performance – HPV pumps provide stable delivery volume under varying loads, which contributes to the efficient operation of the hydraulic system.
- Adjustable volume – the design with an inclined washer allows you to precisely change the working volume depending on the needs of the equipment, which saves fuel.
- Reliability and durability – pumps are designed to operate in harsh conditions, withstand high pressure (up to 350–400 bar) and heavy loads.
- Compactness and ease of installation – perfectly integrated into the hydraulic systems of Komatsu construction and quarry equipment.
- Low noise and vibration levels – modern engineering solutions reduce the acoustic load on the operator.
- Serviceability – wide distribution and support make it easy to find spare parts and carry out repairs.
- Energy efficiency – the optimal ratio between power, feed and energy consumption increases the overall efficiency of the machine.
Komatsu HPV hydraulic pumps are most often used in the main working systems of excavators (for example, PC200–PC400 models), where reliable and accurate supply of working fluid to the actuators is required.
