The integrated flanged trap LI-500 is installed inside the diffusion pump instead of the standard oil reflector, without increasing the overall dimensions of the diffusion pump. The LI-500 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 working fluid of the pump is water. The use of the 3VVN1-12M(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 parts. The 3VVN1-12M(H) water ring vacuum pump is not intended for use in fire and explosion hazardous industries. The 3VVN1-12M(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 NV-2400 OH is a large island table with a superstructure that can be placed in the center of the laboratory and organize workplaces on both sides. Table top depth: 152 cm. It is designed for standing work: the height of the table top is 85 cm. Two lamps and four sockets are built into the superstructure on each side. External dimensions of the table (W×D×C): 2420×1520×1650 mm. Work surface for your tasks We offer tables with various work surfaces. Table Model: Tabletop NV-2400 OLH: Laminate. It is relatively moisture-resistant, resistant to short-term exposure to acids, alkalis and organic solvents. This countertop does not tolerate strong heating or prolonged exposure to solvents, concentrated acids and alkalis. NV-2400 OKH: Porcelain tile. It is a practical solution for most chemical, biological, medical laboratories and workshops. You can put drying cabinets, baths and other heating devices on it. NV-2400 OSPH: Chemically resistant plastic. It is a good choice for training workshops, analytical and medical laboratories. It does not tolerate high temperatures well, heating devices should not be placed on the surface. NV-2400 OPH: Polypropylene. It is chemically resistant, being a specialized solution for chemical laboratories that work a lot with concentrated inorganic acids and alkalis. It is not resistant to high temperatures. A large table for convenient work in the laboratory The superstructure allows you to compactly place the necessary reagents and laboratory utensils next to the workplace. Its depth is 30 cm, and its height is 80 cm. This table has plumbing fixtures: two taps and two small sinks made of polypropylene resistant to aggressive chemicals built into the countertop. The diameter of the sink is 135 mm and the depth is 110 mm. The working area on each side is illuminated by two fluorescent lamps (included in the package). The switch is located on both sides of the superstructure. There are also two sockets, one of which is grounded. The sockets (with four on each side, there are eight of them in total) have the IP20 degree of protection, maximum load: 1.5 kW. On each side, three cabinets are built into the table, two with a hinged door and a shelf inside, the third one with three pull-out drawers. You can store there laboratory utensils or small stuff you need at hand. The side laminated panels of the table (chipboard 16 mm thick) are edged on the facade with a 2 mm PVC edge, which increases their impact resistance and mechanical strength. The legs of the table are adjustable in height within two centimeters, allowing you to place it even on a rather uneven floor.

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).
