Spiral Vacuum Pump NVSp-35 for Safe Air and Gas Extraction

The vacuum pump NVSp-35 is designed for pumping from 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 air (21 % by volume) at pressures from atmospheric to ultimate residual, at pressure in the outlet section, not exceeding atmospheric by more than 9.3 kPa (70 mm Hg).hg). The scroll vacuum pump NVSp-35 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)
