● Energy Saving Power consumption less than half that of hydraulic machines and equivalent to that of full electric machines, with reduced.
● Low Noise
● High Performance Special high power servo motor (SPM) and variable displacement piston pump → Improved ultralow speed molding & continuous pressure holding performance and excellent repeatability.
“ASR” Series AC Servo Motor Driven Pumps
Specifications：
Features：
● Low noise
The motor operates at near-zero speed during unloaded operation or pressure control, keeping the noise level extremely low.
● High performance
The AC servo motor, which directly controls the pump speed, improves response and stability at low pressures and speeds.
● Digital AMSR controller that saves space and wiring
The integration of the amplifier for the servo motor and the controller saves space and wiring. The parameters can be digitally
adjusted in an easy and repeatable way.
● Dual displacement type for a wider operation range
The dual displacement type has a solenoid operated directional valve to switch between large and small swash plate angles. A
single pump unit of the dual displacement type can operate both with low pressure/large flow and with high pressure/small
flow. Thus, in comparison to the single displacement type with the same motor capacity, the dual displacement type covers a
significantly wider range of operating pressures and flow rates.
● Large flow
The AMSR controller has a combination function that supports operation with large flow up to 3200 L/min (ASR10 x 16 units)
