Markets

Printing and Paper Industry

Whether you need an individual unit or a system, Becker's vacuum pumps, compressors for blast air, and combined pressure/vacuum pumps are made for the various processes used in the printing and paper industry - from the pre-press stage, to sheet fed and digital presses, to the post-press.
General Mechanical Engineering

Becker provides customised vacuum pump and compressor solutions for numerous mechanical engineering applications across the world, such as conveying, transporting, fixing, lifting, handling, drying, cooling and many more.

Applications

Vacuum Fixing

Vacuum pumps and vacuum systems from Becker are the ideal solution for holding goods and components in place during production, processing, and packaging.
Pick & Place

Many modern production processes require the use of vacuum to transport, lift, and place goods and materials, including feeders for printing, secondary packaging, and other automatic loaders.
Pneumatic Conveying

Low pressure and vacuum solutions are perfect for transferring powders, granules, flakes, and other small, dry, low bulk density products.
Blowing & Injecting

Compressors are used to build up pressure to supply air for the aeration of waste water, blast air for printing, wine presses, drainage system reliners, and other processes.
