Vacuum membrane pump PL.HM04.02.01 PrimeLab is a compact laboratory device with which you can create a vacuum in the laboratory. It is equipped with innovative membrane technology that ensures high gas pumping speed. Suitable for pumping vapors and gases up to 1 mbar. The PL.HM04.02.01 pump has an excellent safety system. Protection against overheating and overload is provided. All contacting media are made of PTFE, which has rare chemical and physical properties. All control is carried out through vacuum control, which also ensures maximum accuracy and control of all operating parameters. It has a low noise level (75 dB), which does not cause discomfort to the working class.

The NVSp-35 dry vacuum spiral pump can operate continuously at an inlet pressure of no more than 10 kPa (75 mm Hg), pumping out one or more sealed vessels with a total volume of no more than 3.5 m3 from atmospheric to residual pressure during the day. Pumping of vessels of the specified volume with leakage is allowed, but the leakage should not cause an increase in pressure at the pump inlet of more than 10 kPa (75 mm Hg).

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

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
