Vacuum Pumps

Vacuum pumps and blowers are designed for handling gases and vapours by sucking in and pumping. They can be used to create a vacuum in technological systems, to flood water siphons, transportation of loose materials, where the production process requires oil-free gases. Depending on the requirements of the specific technological process, a variety of liquids may be used in circulation provided their densities are between 0.7 and 1.8 kg/dm3, viscosities are not higher than 21 mm2/s and the aggressiveness of the liquid is in the range of corrosion resistance of the materials used to design the specific device.
The equipment will handle gases saturated with vapours and containing a small amount of liquids up to 2% of the capacity of the gas handled, as well as those contaminated with traces of non-abrasive solids up to 0.2 mm. It is desirable to use filters on the suction pipe. The pumps and blowers are driven by motors supplied with electric current at the frequencies of 50 and 60 Hz. Other propelling methods are permitted provided the shaft carries the torque moment only. Vacuum pumps are used in:
