Piston Pump

PVD Series Piston Pump
One pump discharges two equal amounts of flow to ensure shovel straightness. Constant horsepower control with full use of engine horsepower, resulting in increased speed and power for mother machine. Compact size enables installation in a small engine room.

PVK Series Piston Pump
Constant horsepower control with full use of engine horsepower, resulting in increased speed and power for mother machine. Load sensing control can be achieved with our DPK load sensing valve, resulting in energy savings for mother machine. Compact size enables installation in a small engine room.

PZ Series Piston Pump
Half-cylindrical swash plate for low noise and low pulsation Spherical valve plate for high efficiency (Employed into 3B, 4B and 6B.) Various capacities ranging from 35 to 220cm³/rev (7 sizes in total) Multiple string option with our IPH series inscribed gear pump. The electro-hydraulic proportional control valve uses the proven force feed-back system for improved hysteresis, repeatability, and response.
