ASR Series AC Servo Motor Driven Pumps

Trump Card for Energy Savings! Ultimate Hydraulic System ASR Series AC Servo Motor Driven Pumps

Eliminates power losses by matching operations to machine requirements. This also minimizes heat emissions from the hydraulic oil and allows use of significantly smaller tank capacities.
To minimize operating noise, the motor slows to a near-stop during uploading and pressure control processes.
Direct AC servo motor control of pump rotation frequency improves response at low pressures and speeds, as well as improving stability.
The servo pack and controller are integrated to reduce wiring. Parameters are set by simple digital adjustments.
A solenoid operated directional valve allows the dual capacity model to switch between small and large capacity, in turn allowing a single pump to handle both low pressure and high flow and high pressure and low flow regimes and significantly expanding the range of pressures and flows the pump can accommodate.
The AMSR controller's totaling function allows the pump to handle flows of up to 3,200 L/min (ASR10 16 units).
