The ISO-KF connection (DIN 28 403 and ISO 2861) allows quick installation and replacement of components in vacuum systems. The connection consists of two symmetrical ISO-KF flanges (1), a centering ring with an O-ring seal (2) and a quick-release clamp (3). High-vacuum ISO-KF connections can be mounted without using a tool by simply turning the nut of the quick-release clamp.

The MU-500 flanged enlarged oil reflector performs the function of an oil reflector, is installed instead of a standard oil reflector in ND pumps and has an additional number of cooled screens for capturing oil return flow vapors.

The use of a 2VVN2-50(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 2VVN2-50(H) pump. The 2VVN2-50(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 working fluid of the pump is water. These pumps are designed to work with liquids as well as gases and vapors slightly soluble in them that are not aggressive to the materials of the 2VVN1-3M pump design, not explosive and non-toxic. The use of a 2VVN1-3M(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 bodies of the 2VVN1-3M(H) pump. The vacuum water ring pump 2VVN1-3M (H) is manufactured in the climatic version of UHL (i.e. for moderate and cold climate) 4 and O4 according to the 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 LP-250 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.

The ZVPlE-500 shutter consists of a housing with connecting flanges, a shutter mechanism, a lip seal to ensure the tightness of the drive element, cover, and electric drive. The shutter mechanism consists of a carriage, an upper and lower flap, which are pulled together by springs and balls. The carriage moves along the housing guides on bearings. The ZVPlE-500 shutter is opened and closed both by electric drive and manually using a flywheel. To switch to manual control mode, there is a switching device on the electric drive. The manual drive is used to adjust and regulate the shutter. ZVPlE-500 valves are manufactured in climatic versions UHL (i.e. for moderate and cold climate) and O (i.e. general) 4 according to GOST standard 15150-69.

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.

The AVDM-250 high-vacuum unit is a structure consisting of a vacuum diffusion oil-vapor pump, a nitrogen trap, a vacuum gate, a frame or a plate. The principle of operation of the AVDM-250 unit is based on the pumping action of a vacuum diffusion steam oil pump. When the AVDM-250 unit is operating, liquid nitrogen is poured into the trap. Condensation of working fluid vapors occurs on the elements of the freezing device cooled with liquid nitrogen. The frame (plate) is designed for mounting the components of the unit. The ends of the wires are connected to a connector mounted on the frame of the AVDM-250 unit.

The nitrogen flow trap LAP-100P is designed to protect vacuum pumps from contamination in the form of vapors of resins, oils and adhesives by freezing them on cooled surfaces with the possibility of their removal, and to prevent the penetration of vapors of working fluids of vacuum pumps into the pumped vessel.
