The working fluid of the pump is water. The use of the 3VVN1-6M(H) 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 engine and destruction of the pump's working organs. The 3VVN1-6M(H) water ring vacuum pump is not intended for use in fire and explosion hazardous industries. The 3VVN1-6M(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 3648-053-00218526-2013, designed and manufactured taking into account the requirements of GOST R 52615-2006.

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 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 SNVS-40/5 vacuum drying cabinet with a volume of 40 liters with manual vacuum adjustment is designed for heat treatment of materials at temperatures up to 500 with air access and in a vacuum controlled by manual valves. Thanks to modern temperature control, it demonstrates excellent performance of heat treatment modes. The measurement system complies with Russian standards and has certificates of entry into the SI State Register. Design for heat treatment in production and clean laboratories. The cabinet can be equipped with a software control device with an automatic timer and a wide selection of additional options.

Vacuum resistance furnaces are necessary for heating products before pressure treatment, for sintering, degassing, quenching, annealing, soldering and chemical-technological processes. Such furnaces among all the variety of thermal equipment are considered the most environmentally friendly – heat treatment is carried out at t up to +2500 ° C in a purified vacuum. Under certain conditions, vacuum furnaces are used to work with neutral gases. The outer part of the furnace is made of stainless steel and is cooled by liquid. The inner part of the working chamber, where the heat treatment of materials is carried out, is made of an alloy of molybdenum and tungsten. The components are characterized by a low inertia force, reduced gas separation. The settings are available on the control panel, where the instruments, automatic and manual control switches are located. At every enterprise of the electronic industry, nuclear power, an explosion-proof vacuum resistance furnace is needed. The same applies to areas where various products undergo heat treatment at the stage of production and preparation for use.

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.
