The 2NVBM-630(R)/12000 booster pump consists of housings, a steam pipe, a trap and a heater. The required effective speed of action of the pre-vacuum pump (pumps) at a pressure of 200 Pa (1.5 mm Hg) at the outlet of the 2NVBM-630(R)/12000 booster pump is not less than 100 l/s. The maximum residual pressure of the pump measured by the PMI-2 manometric ionization converter with nitrogen filled into its trap, is no more than 6.6x10-4Pa (5x10-6mm Hg). The pressure of the cooling water at the pump inlet 2NVBM-630(P)/12000 should be from 0.2 to 0.5 MPa (from 2 to 5 kgf / cm2) The discharge from the pump should be free with a jet break. Cooling water consumption 1200 l/h. The total amount of working fluid for the 2NVBM-630(R)/12000 pump is 65 liters, the level of the working fluid should be between the upper and lower marks of the level gauge. Replacement or refilling of the working fluid depends on the operating mode of the pump (inlet pressure, pumping duration, etc.) and the composition of the pumped medium, so the time after which the working fluid is replaced or refilled can be 100 hours or more. A large flow rate of the working fluid is observed when the pump is operating in the input pressure range from 1.33 to 13.3 Pa (from 1x10-2 to 1x10-1 mmHg). The operating mode of the pump in the range from 13.3 Pa (0.1 mmHg) to the maximum residual pressure is cyclically irregular.

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 AVB-3 vacuum water ring unit consists of a 3BBH1-3M vacuum water ring pump and an EV-3M water ring vacuum ejector.

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 2ZVE-630/400R vacuum shutter with electromechanical drive equipped with 630 / 400mm conditional passages is designed to overlap vacuum systems in the range of operating pressures from 1x10-6do 1,07x105Pa (0,75x10–8do 800 mm Hg). The 2ZVE-630/400R shutter is pendulum-type. The 23VE-630/400R shutter is 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 working environment is air or non–aggressive gases. It is not intended for use in fire hazardous and explosive industries. The 23VE-630/400R shutter meets the requirements of technical specifications TU 3648-040-00218526-2003. According to the method of protecting a person from electric shock, it belongs to Class I electrical equipment according to GOST 12.2.007.0-75.
