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

the 2NVR-250D vacuum pump is manufactured in the climatic version of UM 4 (i.e. for moderate climate) according to GOST standard 15150-69, but to be used at ambient temperature and pumped medium 283 K to 308 K (+10˚C to +35˚C). Electricity grid must meet the requrimemnts of GOST 13109-97. The 2NVR-250D vacuum rotary vane pump meets the requirements of technical specifications TU 3648-006-00218526-2002. The 2NVR-250D pump is refueled with VACMA OIL 100 power fluid. The level of the working fluid is monitored by the oil indicator, replenishment is needed when the level of the power fluid is below the minimum level of the oil indicator.

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 dimensions of the DN are 10,16,20,25,32,40,50.

The 2MO-5 oil separator is installed on the exhaust flange of the pump by means of a quick-release connection, and can also be connected through a pipeline, if there is no possibility of placement on the exhaust flange. If you purchase the 2MO-5 oil separator as an independent product, it is necessary (only for the 2NVR-5DM pump, which has threads in the housing) to remove the pump housing and the exhaust olive, install the fitting instead of the olive with a nut and seal, lay the mesh inside the fitting, install the oil separator with a quick-release clamp, ring and seal.

The LP-400(R) 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.
