Rotary Vane Vacuum Pumps (oil-free)

Simplicity of design with only one shaft and direct drive produces robust, long-lasting vacuum pumps with low maintenance and running costs. These vacuum pumps  operate completely oil-free; the individual chambers are separated by long-life vanes. 

lready featuring integrated intake filters and control valves, these vacuum pumps can be fitted with other accessories without a problem. The compact cover ensures low noise and heat emission. Optional corrosion protection also makes these vacuum pumps suitable for extracting moist air.

The frequency inverter integrated in the VARIAIR UNIT significantly enhances the performance data of rotary vane vacuum pumps. It matches vacuum pump delivery exactly to customer requirements. Energy consumption is optimised and constant vacuum is guaranteed even where demand is subject to Variation or severe fluctuation. As no unnecessary suction air is generated, noise is kept to a minimum. Dirt from the surrounding environment is kept out of the vacuum pumps. “Gentle” vacuum-pump start-up reduces strain on mechanical components and reliably extends their useful life. Variable Output ranges minimise the number of different types required, thus also providing logistical advantages.

Series X: Becker Innovation with Top Warranty

Pneumatic technology of the Becker brand is worldwide a synonym for precisely dosed, smooth industrial processes in many industrial sectors. For application areas with high requirements, as they are common for example in the electronics industries, Becker offers the vacuum pump product line: the series X.

With this special development [suitable for the application], Becker extends its popular VT/KVT/VTLF product range by the models VX/KVX/VXLF.

Equipped with specially developed vanes, these oil-free rotary vane pumps distinguish themselves by high abrasion resistance and with that extremely long service lives. And since no dust develops where there is virtually no wear, the devices of the series X are perfectly suited for precision processes under clean room conditions.

The innovation branded by Becker is outstanding not only because of its 100 percent oil-free operation, excellent degree of efficiency and low power consumption. In the area of sensitive vacuum, series X also guarantees precise low-pulsation air conduction.

And to top that, Becker offers for the first time full warranty of at least 20,000 maintenance-free operating hours for this innovation – a guarantee for top technology with the following advantages:

• quick, clean, quiet
• oil-free
• vibration stable
• wear resistant
• energy saving
• long-life reliable

An additional reliability plus is the on-site service by Becker in case of need. Exchange installations and the downtimes associated with that are no longer an issue anymore.

Rotary Vane Vacuum Pumps                       (oil-lubricated)

Simplicity of design with only one shaft and direct drive produces robust, long-lasting vacuum pumps with low maintenance and running costs. The vanes are sealed by the metered supply of oil. Already equipped with integrated non-return valves and an efficient oil Separation system, these vacuum pumps can be fitted with other accessories without a problem. …

The standard-featured circulating-oil lubrication system with integrated oil cooler and cover additionally minimise noise emission. Controlled by a float valve, the oil return suction system also makes these vacuum pumps suitable for use in rough-vacuum applications. Optional water cooling significantly prolongs the life of the oil, even in difficult ambient conditions.

Optional gas ballast valves prevent condensing vapours from contaminating the pump oil. The oil-water emulsion arising from contamination reduces the pump effi ciency or leads to a failure. The valve permits a regulated amount of fresh air (the gas ballast) to fl ow into the pump‘s compression chamber. By mixing saturated intake air with unsaturated fresh air, condensing is suppressed.

The new size between U 4.250 and U 4.400.

U 4.300 – U 4.250: comparison and differences:

• realization of faster pump-down times
• realization –for example– of more packaging cycles per unit time
• as far as possible to keep up with the dimensions
• to keep up with the installed motor capacities of 5.5/6.3 kW respect. 7.5/8.6 kW (50/60 Hz)
• in general: rise in productivity of our customers machines and systems
• increased air flow
• decreased dead storage capacities
• no differentiation between versions SA/K and F/K; the only remaining pump is a version with a final pressure of

Screw Vacuum Pumps

ABS offers Becker’s rotary dry screw pumps, driven directly by an integrated frequency inverter, these pumps no longer require any drive transmission. The area in which the units work is 100% oil-free. The integrated speed governor optimises the use of energy by matching delivery to actual demand. This creates high efficiency levels and minimises energy consumption. Suction air remains pulsation-free all of the time. 

Side Channel Vacuum Pumps

Using “multi-stage” compression, side channel vacuum pumps generate low-pulsation suction air. ABS provides this vacuum pump that has perfected impeller design with curved blades guarantees Optimum efficiency. 

Separation of the compression chambers on both sides of the impeller permits single-stage, twin-flow as well as two-stage, single-flow operation with only one impeller. Vacuum filter and vacuum safety valve can be integrated as an optional extra in the patented design of the sound absorbers. The sound absorbers can be varied in length, affording flexible adjustment to available installation space.

The frequency inverter integrated in the VARIAIR UNIT significantly enhances the performance data of side channel vacuum pumps. It matches the vacuum generators exactly to customer requirements. The patented, sensorless control system that keeps pressure and volumetrie flow constant ensures steady operation, even where differing suction-air rates or pressure levels are demanded. The speed range up to 6000 min^-1can be used to create compact, high-output units. The integrated electronic self-protection feature on the vacuum pumps saves the need for costly accessories, such as safety valves or suction sound absorbers. As no unnecessary suction air is generated, suction noise is kept to a minimum. Matching delivery exactly to the amount of air actually used guarantees optimised energy consumption.

Becker’s innovative VASF 50, 80, and 120 range of side channel blowers is particularly well suited to meeting requirements of the type placed on de-centralized vacuum or pressure generators in terms of system integration and operating efficieny by forward-pointing technoligies. Compact design, optimized aerodynamics, wide speed range with extremely low operating noise as well as “intelligent” drive electronics provide the basis for excellent performance and efficiency while keeping size and weight to a minimum. Modular design flexibility is the key to a single- or multi-stage version with AC or DC drive. A leap forward in technology ultimately expressed in a clearly defined, slim-line exterior.

Radial Vacuum Pumps

Radial vacuum pumps achieve high delivery volumes with very little pulsation. The frequency inverter integrated on the motor provides the capability of matching volumetric flow exactly to customer requirements.

Accessories, such as intake filter or air discharge sound absorber, are available as optional extras.
