The 2NVBM-160(R)/1000 booster pump is a structure consisting of housings, a steam pipe, a trap and a heater. The alignment of the steam line in the 2NVBM-160(R)/1000 pump housing is carried out by a rod inserted into the hole of the hood (oil reflector) and screwed into the upper part of the steam line. The required effective speed of action of the pre-vacuum pump (pumps) at a pressure of 93 Pa (0.7 mm Hg) at the outlet of the booster pump 2NVBM-160(P)/1000 is not less than 15 l/s. The maximum residual pressure of the 2NVBM-160(P)/1000 pump, measured by the PMI-2 manometric ionization converter with nitrogen filled into its trap, is no more than 1.3×10-3 Pa (1×10-5 mm Hg). The pressure of cooling water at the inlet to the 2NVBM-160 pump should be from 0.2 to 0.5 MPa (from 2 to 5 kgf/cm2). The drain from the pump must be free with a jet break. Cooling water consumption is 145 l/h. The total amount of working fluid for the 2NVBM-160(P)/1000 pump is 5 liters., the level of working fluid should be between the upper and lower risks 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 operating mode of the pump in the range from 13.3 Pa (0.1 mmHg) to the maximum residual pressure is cyclically irregular.

The complex includes: single-flow turbomolecular vacuum pump VGTN-400; 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 updated 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 manufacture of a turbine from a solid billet and a special, rigid design of the bearing assembly.

The 2NVBM-500/12000 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 booster pump is not less than 100 l/s. The maximum residual pressure of the 2NVBM-500/12000 pump measured by the PMI-2 manometric ionization converter with nitrogen filled into its trap, is no more than 6.6 × 10-4Pa (5 × 10-6 mm Hg). The pressure of the cooling water at the inlet to the pump 2NVBM-500/12000 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-500/12000 pump is 65 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 operating mode of the pump in the range from 13.3 Pa (0.1 mmHg) to the maximum residual pressure is cyclically irregular.

The operation of the NVDM-250 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-250 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-250 open-type diffusion pump heater is a metal housing with a ceramic base laid in it with a heating element in the form of a spiral made of nichrome wire. 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 mmHg). 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 4°C to plus 25°C. The recommended cooling water consumption is 100+15 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 mmHg) The level of the working fluid during operation, at which the parameters of the pump NVDM-250 are provided, must correspond to min 8mm, max 13mm. The volume of the filled working fluid is 0.55 l

Vacuum membrane pump PL.HM02.01.8 Primelab is a universal laboratory device, the performance of which can be adjusted for each task separately. Depending on the method of connecting the chambers, its productivity can be 38 l/min and 76 l/min with a maximum residual pressure of 8 and 45 mbar. With independent connection, 38 l/min for each chamber. A carefully thought out security system ensures a long service life of the device. Complies with IP20 protection class. It makes virtually no noise during operation (up to 75 dB), which does not cause discomfort when the pump is constantly running. It has small dimensions (321x140x200 mm), allowing the device to be placed in an already equipped space. Supplied complete with equipment sufficient for quick assembly and operation of the device.

The working condition of the ND-250(P) 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-250(R) diffusion pump is a maximum of 1.8 liters, a minimum of 1.3 liters. The viewing window for visual inspection of the working fluid has labels of its maximum and minimum amounts. During normal operation of the pump, the level of the working fluid almost 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-250(R) diffusion pump using the same 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 pump up to 320˚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 160 l/h, for the oil reflector it is 20 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).
