PHV Series Travel MotorFeatures All-in-One Design

All required components for track drive motor are in one unit. (planetary gearbox, hydraulic motor, negative type parking brake,shockless relief valve, anti-cavitation check valve, other optional valve.)

High ReliabilityAll main parts, including special-made angular ball bearing in gearbox, are made and tested by NACHI.

High EfficiencyThe axial piston motor can maintain good efficiency at highpressure ranges. It reduces engine stall, and enables better machine maneuverability.

Auto Kick DownSpeed changed automatically without operating a selector switch.

PVD Series Split Flow Piston PumpFeatures Compact

Easy installation in the engine room due to very short overall length. Less Than1% Flow Difference

Flow difference between each port is minimum. High Efficiency

Axial piston pump can maintain high efficiency at high pressure ranges. Total Horsepower Control - The Engine Will Never Stall

The constant horsepower control, including feedback from option gearpump, can keep the pump drive power under the engine power curve.

Optional Gear PumpSingle or double gear pumps can be installed on the back ofpiston pump.
