Rotary vane 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. Already 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.

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.

Screw vacuum 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. Various accessories, such as intake filter, non-return valve, sound absorbers as well as the air delivery and discharge system, are integrated in the completely soundproof cover structure.

Side channel vacuum pumps

Using "multi-stage" compression, side channel vacuum pumps generate low-pulsation suction air. 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.

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.
