The NVD-600 two-rotor vacuum pump is not designed for pumping air, vapors and vapor-gas mixtures from one volume to another. The NVD-600 two-rotor pump can only work in conjunction with a pre-vacuum pump, and is designed for pumping in the pressure range from 1.3·102Pa (1 mm Hg) to the maximum residual pressure. The speed of action of the forvacuum pump for NVD-600 is not less than 60 m3/h. The temperature of the pumped media at the inlet to the pump NVD-600 should not exceed the maximum operating values of the ambient temperature according to GOST standard 15150-69, at which the pump is operated. At an operating pressure of more than 5 mm Hg for the HVD-600, the bypass valve is in the open position. The pumped gas is partially bypassed through channels in the pump housing from the outlet to the inlet of the pump NVD-600, which ensures the operability of the pre-vacuum pump and prevents overheating of the pump NVD-600. The NVD-600 double-rotor vacuum pump 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 7.5 m3 for the pump from atmospheric to the maximum residual pressure for 8 hours.

The operation of the NVDM-160 diffusion pump is based on the capture and transfer of the pumped gas by a steam jet flowing from the slit gaps of the steam line nozzles towards the outlet flange. The oil reflector of the NVDM-160 diffusion pump is a flange with a cooling tube passing through it, soldered to a cap located in the center of the flange. The NVDM-160 closed-type diffusion pump heater consists of tubular electric heaters fixed in the heater housing. During the operation of the pump, it is necessary to monitor the flow rate and temperature of the cooling water, the level of the working fluid and its temperature. 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. Therefore, the time after which the working fluid is replaced or refilled can be from 100 to 1000 or more hours. A large flow rate of the working fluid is observed when the pump is operating in the range of inlet pressures from 6.6×10-2 to 13.3 Pa (from 5×10-4 to 1×10-1 mm Hg). Water at the inlet to the cooling systems of the housing and oil reflector must be supplied with a pressure of no more than 0.5 MPa (5 kgf / cm2) and temperature from plus 40C to plus 250C. The recommended cooling water consumption is 60+10 l/h and is regulated by the outlet water temperature, which should not exceed plus 400C. The water drain should be free (with a jet break). Not allowed: operation of the pump without water cooling, exceeding the maximum exhaust pressure of 33.3 Pa (0.25 mm Hg). The level of the working fluid during operation, at which the parameters of the NVDM-160 pump are provided, must correspond to min 10mm, max 17mm. The volume of the filled working fluid is 0.3 liters

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 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 working condition of the ND-630 diffusion pump depends on the temperature of the working fluid in the pump boiler. During the initial filling, it is recommended to fill the maximum volume of the working fluid. Working fluid is "VACMA OIL 500" vacuum oil (uner technical specifications TU 19.20.29-061-00218526-2019). The total amount of working fluid in the ND-630 diffusion pump is a maximum of 9 liters, a minimum of 6 liters. The viewing window for visual inspection of the working fluid has marks of its maximum and minimum amounts. During normal operation of the pump, the level of the working fluid practically does not change. The temperature of the working fluid when the pump is operating at the maximum residual pressure is about 240°C to 255°C. It is recommended to monitor the operation of heaters in the ND-630 diffusion pump using one temperature sensor. The temperature sensor must be installed in a special radiator socket above the heater. If there is a loss of working fluid and an increase in the temperature of the radiators of the ND-630 diffusion pump up to 360°C, the temperature sensor must give the command to automatically turn off the heaters. The subsequent activation of the pump heaters should not be automatic and should be performed only after cooling the system. Water at the inlet to the cooling systems of the housing and the oil reflector must be supplied with a pressure of 0.3 MPa (3 kgf/cm2) to 0.5 MPa (5 kgf/cm2) and a temperature of plus 4°C to plus 25°C. The recommended cooling water consumption for the housing is 600 l/h, for the oil reflector it is 80 l / h. It is regulated by the outlet water temperature, which should not exceed plus 40°C. The water drain should be free (with a jet break).

The complex includes: single-flow turbomolecular vacuum pump VGTN-150; frequency converter; set of mounting parts; operation manual. For connecting to the pre-vacuum pumping system, the pump is equipped with an ISO-KF25 exhaust flange. If necessary, it can be upgraded with an ISO-KF16 flange for purging the pump with inert gas. Pump cooling is combined. Based on the operating conditions, the complex can work both with forced air cooling and with water cooling. The working orientation in space is arbitrary. One of the key features of the pump is that a breakthrough of the atmosphere is possible. This has become possible due to the production of a turbine from a solid billet and a special, rigid design of the bearing assembly.
