Elmo Rietschle S-VSI 301 – dry-running screw vacuum pump
The S-VSI 301 delivers 300 m³/h at 50 Hz and 360 m³/h at 60 Hz and reaches 0.08 mbar (abs.) in continuous operation. It compresses dry and without contact; according to Elmo Rietschle, the stepped screw profile provides high efficiency and low operating temperatures. Typical uses are packaging and drying processes with short cycle times.Cooling
Three cooling variants: once-through cooling (01, cooling water consumption 6.7 l/min, max. inlet temperature 45 °C), circulation cooling with water-air heat exchanger (31) or with water-water heat exchanger (61, cooling water pressure 0.6–1.2 bar).Motor and dimensions
Flange-mounted motor 7.5 / 9.0 kW (50 / 60 Hz, IE3) or IE4 motors with 5.5 kW (50 Hz) or 7.5 / 9.0 kW. Depending on the cooling variant and version: length 1246–1555 mm, width 429–569 mm, height 597–666 mm, weight 335–389 kg. Vacuum connection G 2, oil filling 1.4 l (two filling points, 0.8 and 0.6 l).Advice and service
