Spiral Vacuum Pump HVSp-12 for Air Removal and Non-Aggressive Gases

Spiral vacuum pump NVSp-12 is designed for pumping out of hermetic volumes of air and non-aggressive to materials of construction, fire-explosion safe non-toxic gases, pre-cleaned from dripping moisture and mechanical contaminants, with oxygen content not more than in air (21 % by volume) at pressures from atmospheric to ultimate residual pressure, with pressure in the outlet section not exceeding atmospheric pressure by more than 9.3 kPa (70 mm Hg).hg). The volute vacuum pump NVSp-12 is designed for operation in stationary and mobile installations. Type of climatic execution of the pump is UHL4 according to GOST 15150-69, but for operation at ambient air and pumped medium temperature from 283 K to 308 K (from +10 0C to +35 0C). The pump is designed for operation in premises with atmosphere type II according to GOST 15150-69 at atmospheric pressure from 84,0 to 106,7 kPa (from 630 to 800 mm Hg)
