Kawasaki K3V Piston Pump The spherical valve plate and improved hydraulic balance make the cylinder rotation stable, and high efficiency can be achieved even in the low-pressure and low-speed operating range. K3V63 K3V112 K3V140 K3V280 has a large main bearing capacity, and the piston return mechanism can compensate for the wear of the sliding shoe, and the service life is long. The optimal design of the valve plate and housing rigidity reduces noise.
1. High power density
The Kawasaki K3V Piston Pump achieves a lighter, more compact machine with a higher pressure rating and higher power density (output power/mass) by adopting a semi-logarithmic swash plate.
In particular, the use of a double pump in a tandem arrangement eliminates the need for a power divider, improves transmission efficiency, and is lighter.
2. High efficiency and large self-priming capacity
The spherical valve plate and improved hydraulic balance provide stable cylinder rotation, thereby achieving high efficiency even in the low-pressure and low-speed operating range.
3. Long life
The Kawasaki K3V hydraulic pump adopts a large-capacity main bearing and a piston return mechanism that compensates for shoe wear, which achieves long life.
4. Low noise
Noise is further reduced due to the optimized design of the valve plate and housing rigidity.
5. Wide range of control
The Kawasaki K3V pump can be controlled using a variety of control methods and can respond to mechanical, hydraulic or electrical inputs.
