K3PU Series

K3PU Series
  • The high pressure and large capacity pump with ample experience is combined with an electric motor by introducing a unique bellhousing. This development realizes compact pump units. Furthermore the flexible mount of the hydraulic pump alleviates the vibration and system noise.

Features

  • A high-pressure and large-capacity type axial piston pump is used. (Kawasaki K3VG series)
  • A flange mounted type (JIS) electric motor is used.
  • A hydraulic pump and an electric motor are directly assembled to the bellhousing, so it saves you the centering work.
  • It is possible to attach a relief valve block to the hydraulic pump delivery port.

※Boost pressure is necessary for suction port that 4P of K3PU280 is used in 60Hz.

Option

REDUCED PRESSURE PULSATION TYPE

  • An optional pressure pulsation absorber is available for lowering the system noise.
Option

Pulse Dampers

  • The Pulse Damper installed in the pump's delivery line effectively absorbs the pulsating flow and the noise.
