“A3H” Series Pumps

These A3H Series variable displacement piston pump offer high pressure, high efficiency, high speed and low noise features. This pump series has been developed using Yuken’s unique design concept and cumulative technologies.

They are suitable for use with construction machinery and various industrial machinery ranging from presses to injection moulding machines.

FEATURES

• High Efficiency
  High performance at maximum pressure 35MPa volumetric efficiency is over 95% and overall efficiency is more than 90% at 1800 r/min.

• Compact Size
  A3H series are compact in size because output/mass ratio is large.

• “ASR” Series AC Servo Motor Driven Pumps
  The ASR series provides variable flow by driving a piston pump directly with an AC servo motor and controlling the rotational speed in a range from zero to the maximum level.
  This series allows for precise control of flow/pressure by using a dedicated AMSR controller. It also offers excellent response and repeatability.

• “ASE” Series AC Servo Motor Driven Pumps
  The ASE series pumps inherit the basic concept of the shaft speed control from the ASR series pumps and offer high cost performance.
  The pumps of this series offer easy shaft speed control for systems that do not require as much precision, response, or repeatability as the ASR series pumps offer.
  With the output flow and the discharge pressure controlled by a dedicated AMSE controller, precision, response and repeatability of systems using the ASE series pumps have been improved compared with those using conventional variable displacement piston pumps.

“ASR” Series Pumps

The ASR series provides variable flow by driving a piston pump directly with an AC servo motor and controlling the rotational speed in a range from zero to the maximum level.
