DZS 600 VSD+ 1951001105 3Ph 460 V 60 Hz, NEMA-version (USA)

Atlas Copco DZS 600 VSD+ – large claw pump with integrated inverter

According to the brochure, the DZS 600 VSD+ delivers up to 600 m³/h and reaches 200 mbar(a) in continuous operation. The rated motor power is 11 kW; the operating instructions state a speed range of 1200–3600 rpm (20–60 Hz). Dimensions 1362 × 586 × 969 mm (L × W × H), unit weight 457 kg (IEC) / 464 kg (NEMA). Inlet G 3", outlet G 2 1/2".

Continuous operation at ultimate vacuum

Thanks to the integrated VSD+ inverter drive and the pressure setpoint control, the pump matches the motor speed to the load coming from the process. According to Atlas Copco, it can work continuously at ultimate vacuum level without overheating. The frequency inverter is flange-mounted on top of the motor and provides pressure-based speed control, STO function, temperature protection, Modbus RTU and Bluetooth.

For rough vacuum with low maintenance effort

Atlas Copco describes the DZS 600–1200 VSD+ range as durable, robust pumps with very low maintenance requirements for rough vacuum applications.
