The use of a 2VVN1-6M(H) water-ring vacuum pump for pumping out water-gas mixtures is allowed only if the bulk of the water is separated and discharged at the pump entrance. Failure to comply with this requirement may lead to unacceptable overload of the electric motor and destruction of the details of the 2VVN1-6M(H) pump. The 2VVN1-6M(H) vacuum water ring pump is manufactured in the climatic version of UHL (i.e. for moderate and cold climate) 4 and O4 according to GOST standard 15150-69, meets the requirements of technical specifications TU 3648-015-00218526-2000, designed and manufactured taking into account the requirements of GOST R 52615-2006. Electricity grid must meet the requrimemnts of GOST 32144-2013.

The AVD-50/16 unit consists of a NVD-200 series-connected two-rotor vacuum pump and a 2NVR-60D plate-rotor vacuum pump. The pumps are connected to each other by means of an adapter, which acts as both a pipeline and a support unit. The AVD-50/16 unit can operate continuously at an inlet pressure of no more than 133 Pa (1 mm Hg) or pumping out one or more sealed vessels with a total volume of 3.5 m3 from atmospheric to maximum residual pressure for 8 hours.
