About the series

Features and benefits of the VT / KVT / VTLF series

The series at a glance

With integrated intake filters and regulating valves as well as a compact cover hood, the pumps offer easy installation, low noise emissions and low heat radiation. Depending on the version, optional corrosion protection also allows humid air to be conveyed.

The VARIAIR UNIT with integrated frequency inverter automatically adapts the pump output to actual demand. This reduces energy consumption and intake noise, ensures a constant vacuum and minimises the mechanical load during start-up.

With the VT, KVT and VTLF series, Becker underlines its commitment to reliable, efficient and oil-free vacuum technology. The versatile vacuum pumps offer a robust construction, low operating costs, low maintenance requirements and a long service life – for high productivity and reliable performance in a wide variety of industrial applications.

Efficient

The Becker VT, KVT and VTLF vacuum pumps offer efficient, oil-free vacuum generation and reliable continuous operation. Their compact design and optimised drive allow space-saving installation combined with high vacuum performance. Depending on the range, different performance sizes are available, so the pumps can be adapted flexibly to various industrial applications.

Robust design

The VT, KVT and VTLF series are characterised by a robust and durable construction. The proven oil-free rotary vane or claw technology allows reliable operation with low maintenance requirements. High-quality, low-wear components support a long service life and make the pumps a reliable solution for continuous industrial use.

Clean operation

The oil-free technology of the Becker VT, KVT and VTLF vacuum pumps allows clean and reliable operation without oil in the compression chamber. This reduces the risk of oil contamination of the pumped medium – an important advantage for applications that require clean process air and reliable vacuum generation. At the same time, dry operation supports low-maintenance and economical plant operation.

Operating principle

The Becker VT, KVT and VTLF series are based on proven dry-running technology and operate completely oil-free. Depending on the range, robust rotary vane or claw principles are used, which allow reliable vacuum generation without operating fluids such as oil. This makes the pumps particularly suitable for applications that require clean and oil-free process air.

The precisely manufactured components and low-wear materials ensure efficient operation, low maintenance requirements and a long service life. At the same time, the Becker pumps offer a compact design, low energy consumption and reliable vacuum performance – even in demanding industrial applications.
