Made in: Japan
Manufacturer: NACHI
Model: PVK Series

Features

• 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.

Application

• Ideal for mini-shovel pump
• If you use this unit in a set with our company’s load sensing valve DPK the unit contributes to energy saving in the mother machine through load sensing control.

Specifications

• Various pump sizes available to match anything from a 1.5-ton mini-shovel to a 5-ton shovel.
• Gear pump highly efficient for pilot operations is standard equipment, and can be used as a stable hydraulic source for various kinds of controls for the mother machine.
