The 3VVN1-25(H) water ring vacuum pump is not intended for use in fire and explosion hazardous industries. The 3VVN1-25(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 3648-053-00218526-2013, designed and manufactured taking into account the requirements of GOST R 52615-2006

The LI-400 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-400 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 3KN-2,5 intake valve includes a nut, the filter is installed in the housing between the two rings. The opening of the inlet valve 3KN-2,5 is carried out when the electromagnet coil is de-energized and the armature returns to its original position under the mechanical pressure of the spring. The closure of the 3KN-2,5 intake valve occurs when an electric voltage of a certain power is applied to the terminals of the coil. The anchor is involved in the shoe, ensuring the closure of the ductal canal.

The 2NVBM-400(R)/6000 booster pump consists of housings, a steam line, 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 booster pump 2NVBM-400(R)/6000 is not less than 45 l/s. The maximum residual pressure of the pump 2NVBM-400(R)/6000, measured by the PMI-2 manometric ionization converter with nitrogen filled into its trap, is no more than 6.6 × 10-4 Pa (5 × 10-6 mmHg). The pressure of the cooling water at the inlet to the pump 2NVBM-400 (R)/6000 should be from 0.2 to 0.5 MPa (from 2 to 5 kgf / cm2). The drain from the pump should be free with a jet break. Cooling water consumption is 600 l/h. The total amount of working fluid for the 2NVBM-400(R)/6000 pump is 47 liters, the level of 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 1 ·10-2 to 1 ·10-1 mm Hg). The pump operating mode in the range from 13.3 Pa (0.1 mmHg) to the maximum residual pressure is cyclically irregular.

The AVD-50/16 unit consists of a NVD-200 series-connected two-rotor vacuum pump and a 2NVR-60D plate-rotor 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-50/16 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.
