Core Advantages
Designed for demanding hydraulic power transmission, this piston pump combines variable displacement technology with precise swashplate control. The flow can be adjusted continuously according to drive speed and system demand, helping improve operating efficiency in mobile and industrial equipment.
A compact housing, low weight, and favorable power-to-weight ratio make the pump suitable for space-limited hydraulic systems. Low noise, strong suction ability, and high-speed rotation capability contribute to smooth and reliable operation.
The pump supports pressure control, power control, and electric proportional control for flexible system configuration. Its short response time and accurate control characteristics help improve hydraulic responsiveness. Durable bearings support long-term operation, while the through-drive structure enables multiple pumps to be connected in series.
The pump provides a rated working pressure of 250 bar and a peak pressure of 315 bar, offering reliable performance in high-load and harsh working environments.
