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 working condition of the ND-500 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 (under technical specifications TU 19.20.29-061-00218526-2019). The total amount of working fluid in the ND-500 diffusion pump is a maximum of 5.5 liters, a minimum of 4 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 the heaters in the ND-500 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-500 diffusion pump up to 320°C, the temperature sensor should give the command to automatically turn off the heaters. The subsequent activation of the pump heaters should not be automatic and should be carried out 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 500 l/h, for the oil reflector it is 50 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 required speed of action of pre-vacuum pumps at a pressure of 26 Pa (0.2 mm Hg.st) in the outlet section of the ND-500 diffusion pump should be at least 42 l/s. To reduce the losses of the working fluid of the ND-500 diffusion pump at pressures (1·10-1- 1) Pa [(7,5·10-4- 7,5·10-3) mmHg] it is recommended to install an additional LP-500 flow-through water trap on the outlet flange.
