Orion KHA400-309-G1 Dry Vacuum Pump – 400 m³/h, Oil-Free, Mitsubishi Motor, IP55

The Orion KHA400-309-G1 is a high-performance dry vacuum pump unit designed for industrial applications requiring clean, oil-free vacuum generation. Manufactured by Orion Machinery Co., Ltd., Japan, this unit is engineered with a dry-running mechanism—either screw-type or roots-type—ideal for sensitive processes in the semiconductor, chemical, and pharmaceutical industries. The system delivers a nominal pumping speed of 400 m³/h and achieves an ultimate vacuum of ≤ 0.01 mbar, making it suitable for low-pressure continuous-duty operations. The pump is integrated with a Mitsubishi Electric SUPER LINE three-phase induction motor (Model SF-JR) rated at 0.4 kW, featuring IP55 protection and Class E insulation, compliant with JEC 2137-2000 standards. Operating voltages range from 200V (50Hz) to 220V (60Hz), with corresponding RPMs between 1410 to 1700 RPM. The pump is skid-mounted, compact, and supports clockwise rotation (as viewed from the motor end). The robust design includes clear flow direction marking and ensures stable performance across a range of pressures from atmospheric down to 1 mbar inlet and up to 1.2 bar outlet. Ideal for precision vacuum systems where oil contamination is unacceptable.
