Specifications:
The S-VSI 300 (44) is a dry running, non-contact operation screw vacuum pump. It operates at 50 Hz with a power rating of 5.5 kW (7.5 hp) and at 60 Hz with a power rating of 7.5 kW (10 hp). The rated voltage is 3~ 400/690 V ± 10% for 50 Hz and 208-230/460 V ± 10% for 60 Hz. The pump has a suction capacity of up to 224 cfm and an ultimate vacuum of 29.92 in. HgV. The full load amperage varies with frequency, and the speed is 2900 rpm at 50 Hz and 3550 rpm at 60 Hz. The average noise level is 74 dB(A) at 50 Hz and 76 dB(A) at 60 Hz. The weight ranges from 695 to 723 lbs depending on the configuration.

Procedures and Maintenance:
The pump is designed for easy servicing and is ideal for applications requiring short evacuation times, such as food processing, packaging, and drying processes. It features high efficiency due to the precision graduation of the screw pitch.

Standards and Recommendations:
The pump's technical information is subject to change without notice. The motor dimensions and full load amperage may vary depending on the motor manufacturer. The curves and tables provided refer to the vacuum pump at normal operating temperature with a tolerance of ±10%.
