K3V series pumps are very popular as reliable power source for construction machines.
Various rotary group layouts are available to respond to applications.
Tandem type with PTO and Parallel type have joined the series. |

With new technology the K5V series has realized higher power density.
K5V series can cope with enlargement of displacement despite the same installation dimensions and regulator variations as K3V, s.
K5V series pumps have realized higher reliability and long life so as to meet requirement of larger torque. |

To meet requirement for small installation space, the total length of the pump is shortened by approximately 10% compared to K3V series.
High efficiency is obtained by optimizing clearance and stabilizing cylinder rotation.
Remarkable noise reduction has been achieved by the latest technologies for noise reduction based on our original research.
A long life is obtained by adopting large capacity of bearing and thicker shaft which reduces the load on the edge of bearing rollers. |
