    Hydraulic Pumps
    SWASH PLATE TYPE AXIAL PISTON PUMPS
  • 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 centrifugal pump
  • 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.

  • with centrifugal pump
  • 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.
