Hydraulic Equipment Manufacturer, Main Pump, Swing Motor, Travel Device, Electro-Hydraulic Steering Gear and more
The K3V/K5V/K7V series are high-efficiency, high-reliability, low-noise swash plate variable displacement axial piston pump for construction machinery.
Features | Benefits |
---|---|
High power density | High power density increased by achieving high pressure, light weight and compactness by adopting a semi-cylindrical swash plate type |
High efficiency and high self-suction ability | By adopting a spherical valve plate and improving the hydraulic balance, high efficiency is realized even in the low pressure/low inclination area. |
Long life | Long life is achieved by adopting a high load capacity bearing and a piston/return mechanism that compensates for shoe wear |
Low noise | Realization of low noise by improving the rigidity of the casing and the design of the valve plate |
Various control methods | Various control methods using mechanical, hydraulic, and electricity are possible |
