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).

It is intended for thermostating samples in glasses, flasks and other laboratory utensils in cases where high accuracy of temperature maintenance is not required and good uniformity of the temperature field in the working volume is not needed. The operating temperature range is Current +5...+200 °C. One workplace with a diameter of 110 mm with five steel O-rings. Stamped steel bath with a volume of 3.5 liters and a depth of 100 mm. Bath volume 3.5 l Overall dimensions 325x195x310 mm The open part of the bath is 235x130 mm Weight 6 kg Power consumption 2.5 kW

NV-800 STP is a mobile table on wheels designed to move heavy equipment around the laboratory. Dimensions of the table assembled (W×D ×H): 730×700×750 mm. It is available with two variants of working surfaces Table Model: Tabletop NV-800 STP: Laminate. It is relatively moisture-resistant, resistant to short-term effects of acids, alkalis and organic solvents. This countertop does not tolerate strong heating or prolonged exposure to solvents, concentrated acids and alkalis. NV-800 STP: 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-800 STP has a metal frame painted with durable powder paint. The side laminated panels (chipboard 16 mm thick) and the lower shelf are edged on the facade with a 2 mm PVC edge, which increases their impact resistance and mechanical strength. The table wheels allow you to conveniently move the equipment around the laboratory. On the bottom shelf you can store equipment accessories or the necessary small stuff. Advantages of NV-800 STP tables Designed to accommodate dimensional equipment; An inexpensive solution for laboratories that value the reliability and durability of furniture; Suitable for the small rooms. Application of NV-800 STP tables Tables of the NV series are used in laboratories of the widest profile: at food and light industry enterprises, in scientific and educational workshops, in chemistry classrooms, quality control centers, medical organizations and many others.
