About the series

Features and benefits of the SV series

The series at a glance

The VARIAIR blowers have an integrated frequency inverter that adjusts the output to demand and thus improves energy efficiency. Depending on the version, integrated inlet filters and vacuum or pressure relief valves are available.

The Becker low-pressure blowers are suitable for numerous industrial applications and stand out for their reliability, high performance, compact design and long service life.

With the SV series, Becker offers a proven range of oil-free side channel vacuum pumps developed for reliable operation, low maintenance requirements and a long service life. The contact-free operating principle enables clean and low-wear vacuum generation without oil or lubricants in the conveyed medium. Thanks to single-stage and two-stage versions, the SV series offers flexible performance options for numerous industrial vacuum applications.

Oil-free and clean operation

The Becker SV series operates completely oil-free and without contact between the moving components. This enables clean vacuum generation without oil contamination, and the pump is particularly suitable for sensitive industrial applications.

Robust and low-maintenance

The contact-free side channel principle ensures low wear and reduces maintenance requirements. The robust design enables reliable continuous operation and a long service life even under regular load.

Versatile in use

The SV series is available as a single-stage or two-stage version and thus offers different performance and vacuum levels. It is suitable for numerous applications such as vacuum lifting, pneumatic conveying, packaging, material handling and general industrial vacuum applications.

Operating principle

The Becker SV series works on the principle of side channel vacuum technology. A contact-free impeller rotates inside the housing and, thanks to the special geometry of the side channel, continuously compresses and conveys the air. Depending on the version, the pumps are of single-stage or two-stage design, which allows different vacuum performance levels to be achieved.

The oil-free and contact-free design enables clean operation without oil or lubricants in the conveyed medium. This makes the SV series particularly suitable for applications that require contamination-free vacuum generation.

The robust design and the low-wear operating principle ensure reliable and low-maintenance operation. The SV series offers high operational reliability and is suitable for numerous industrial applications that require a dry, oil-free vacuum.
