Sumitomo ASE Series Servo Pump | ASE5-4BZ-G130S, ASE3-4AA, AMSE | Servo Motor Driven Pump

Sumitomo ASE & AMSE Series Servo Motor Driven Hydraulic Pumps

Product Overview: The Sumitomo ASE Series is an intelligent power unit that seamlessly integrates high-performance internal gear pumps with precision servo drive technology. As the heart of modern energy-efficient hydraulic systems, the ASE3, ASE5, and AMSE series are engineered for precision injection molding machines, press brakes, and industrial presses. Featured models such as ASE5-4BZ-G130S-B00-3002 and ASE3-4AA-G80S-B00-30 utilize servo motor speed regulation to provide flow and pressure on demand, significantly reducing energy consumption and enhancing operational accuracy.

Key Technical Advantages:

• Ultimate Energy Efficiency: Compared to traditional fixed-displacement pump systems, servo drive technology reduces energy consumption by over 70% during the pressure-holding phase, drastically lowering oil heat generation.

• High Response & Precision Control:

  • AMSE/ASE Logic: The closed-loop control system delivers millisecond-level response for both pressure and flow, ensuring smooth actuator movement and high repeatability.

• Silent Factory Environment: The combination of an internal gear pump (QT pump) and a servo motor eliminates the high-frequency noise of traditional hydraulic stations, vastly improving the workshop environment.

• Low-Speed Stability: Maintains stable system pressure even at extremely low rotational speeds, making it ideal for long holding-pressure cycles in injection molding.

• Integrated & Compact Design: Direct-coupling between the servo motor and pump minimizes installation footprint and reduces mechanical transmission losses.
