BECKER rotary vane oil-free vacuum pumps operate completely without oil. The compression part consists of a rotor eccentrically placed in a stator with graphite vanes with a long service life. The standard equipment includes integrated suction paper filters and control valves, which also function as a safety element, preventing the maximum design overpressure according to the type from being exceeded -850 to -900 mbar(g). Flow rate 2-515 m3h expressed at 20 °C and atmospheric pressure.
BECKER claw pumps are also known as oil-free, because the pumped medium does not come into contact with oil in the compression section. A small amount of gear oil is contained in the gearbox, where the synchronizing gears of the driving and driven shafts are located.
BECKER side channel vacuum pumps are compact, precisely manufactured fans that are capable of reaching a flow rate of up to 1100 m3/h and a maximum vacuum of around -320 mbar(g) in the single-stage version and around -500 mbar(g) in the two-stage version. This is dynamic air compression, where a lot of waste heat is generated, but due to the minimal dimensions and compact design, these vacuum pumps can be used, for example, in the packaging industry, food industry, pneumatic transport, in the aviation industry, etc. The vacuum pumps are practically maintenance-free and reliable.
BECKER radial vacuum pumps are very special, highly efficient and quiet devices for special applications. They are highly precise production of both the centrifugal impeller and other components. The power is regulated by a frequency converter to maximize the efficiency of vacuum production. They are mainly used by laser manufacturers for recirculation of CO2 or other inert gases. In the food industry, this is mainly the reduction of oxygen in food to extend its shelf life, etc.
BECKER oil-free screw vacuum pump is a special PLUG and PLAY system, which is supplied in a sound-absorbing housing, including an integrated frequency converter. These are oil-free pumps. Because there is no oil in the compression space, all thermal energy is available at the discharge, and therefore it can be recovered very effectively, for example into hot water for heating or DHW preparation. The service life of the device is very long and the payback in the case of centralization of compressed air production is not long.
A vacuum pump, technically speaking an industrial vacuum pump, is a device for compressing air and a whole range of other gases. In general, a vacuum pump increases the difference in gas pressure between the inlet and outlet, and this is associated with an increase in flow rate. Depending on what the device is to be used for, we choose the appropriate type so that the compression of a particular type of gas is energy efficient, and most importantly to ensure its long service life. A vacuum pump can transport from a few units of m3/h to several tens of thousands of m3/h of gas at a certain pressure difference. We usually say that the pressure at the outlet of the vacuum pump is always atmospheric, i.e. 1013 mbar(a), or the vacuum pumps are recirculating and here it is necessary to determine the working vacuum, overpressure and flow rate.
