The LI-630 integrated flanged trap is installed inside the diffusion pump instead of the standard oil reflector, without increasing the overall dimensions of the diffusion pump. The LI-630 trap performs the function of an oil reflector, is installed instead of a standard oil reflector in pumps, has an additional number of cooled screens for capturing oil return flow vapors (more than that of the MU trap), covers the entire area of the input high-vacuum flange.

The LP-800 flow-through water trap is installed on the inlet flange of the diffusion pump and is designed to reduce the flow of working fluid vapors into the pumped volume by condensing them on the cooled elements of the freezing device.

ConFlat (CF) standard connections are used to ensure the connection of components of vacuum systems operating in the field of high and ultra-high vacuum.

The use of a 2VVN1-25(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 working parts of the 2VVN1-25(H) pump. The 2VVN1-25(H) vacuum water ring pump is manufactured in the climatic version of UHL 4 and O4 (i.e. for moderate and cold climate) 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. The quality of electricity must meet the requrimemnts of GOST 32144-2013.

The body of the 50M URS valve is of welded construction and consists of a shell, a seat, side and lower nozzles. The lower branch pipe of the 50M URS valve is connected to the vacuum system using welding. The smooth part of the stem serves as a visual indicator of the "open" or “closed” valve positions. The casing is designed to protect the valve from accidental openings, and also serves as additional protection against precipitation, sand, dust entering the inner cavity of the valve. The valve opens when the flywheel rotates counterclockwise. The valve closes when the flywheel rotates clockwise.

The AVD-150/63 unit consists of a series-connected two-rotor vacuum pump NVD-600 and a 2NVR-250D plate-rotary 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-150/63 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 17.5 m3 from atmospheric to maximum residual pressure for 8 hours.

The 2ZVE-160R vacuum shutter with electromechanical drive equipped with 160mm conditional passages is designed to overlap vacuum systems in the range of operating pressures from 1x10-6 to 1.07x105 Pa (0.75x10–8 to 800 mm Hg). The 2ZVE-160R shutter is pendulum-type. The 23VE-160R shutter is manufactured in the climatic version UHL (i.e. for moderate and cold climate) and O (i.e. general) 4 according to GOST standard 15150-69. The working environment is air and non–aggressive gases. It is not intended for use in fire and explosive hazardous industries. The 23VE-160R shutter meets the requirements of technical specifications TU 3648-040-00218526-2003. According to the method of protecting a person from electric shock, the gate belongs to Class I electrical equipment according to GOST 12.2.007.0-75.

The AVD-50/5 unit consists of a NVD-200 series-connected two-rotor vacuum pump and a 2NVR-5DM plate-rotor vacuum pump. 2NVR-5DM and NVD-200 pumps are installed on the lower and upper base of the frame and secured with bolts, nuts and washers. The pumps are connected to each other by means of a pipeline and a bellows assembly. By installing the rings during assembly of the unit, the size of the bellows assembly is set. The AVD-50/5 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.
