1. Rotary Vane Vacuum Pumps

Becker’s durable rotary vane pumps operate on a positive-displacement principle. A rotor with slots rotates in a housing driven by a enclosed, fan-cooled motor. Sliding vanes in the slots move against the cylinder wall, creating separate working chambers.

1.1 Oil Free Rotary Vane Vacuum Pumps

Oil-free or dry-running rotary vane vacuum pumps are ideal for higher pressure differences in vacuum applications. They utilize self-lubricating, carbon-graphite composite vanes that directly contact the cylinder wall. However, this design restricts the achievable vacuum level to 100 mbar absolute.

Small Series (VT/VX)

Medium Series (KVT/KVX/VARIAIR)


1.2 Oil Lubricated Rotary Vane Vacuum Pumps

Becker’s oil-lubricated rotary vane vacuum pumps excel at producing a high vacuum and are ideal for applications requiring precision. Compared to standard vacuum pumps, these pumps offer distinct advantages due to their simple construction and single shaft direct drive design. This results in a durable rotary vane pump with minimal operating and maintenance expenses.

Small Series (O6/O5/U5)

Medium Series (U/VARIAIR/O2-PACK)

Large Series (U4)

2. Screw Vacuum Pumps

Becker’s screw vacuum pumps and compressors, engineered for rough vacuum applications, are dry positive displacement pumps. They feature two counter-rotating rotors enclosed within a housing. With direct drive via an integrated frequency inverter, the need for a drive gear is eliminated.

VADS Series

3. Claw Vacuum Pumps

Becker’s claw vacuum pumps and compressors operate on a positive-displacement principle, akin to rotary vane pumps. These pumps are entirely oil-free and maintain no contact during operation. Two claw-like rotors rotate within a compression chamber, moving in opposite directions without touching each other or the chamber walls.

BCV Series


4. Roots Booster Vacuum Pumps

Roots booster vacuum pumps, also known as roots blowers, are dry positive displacement pumps that function based on the Roots operating principle, akin to rotary vane pumps. They are particularly well-suited for applications requiring rapid pumping speeds.

RBP Series

5. Side Channel Vacuum Pumps

Side channel blowers are used in heavy-duty industrial applications for suction or air blasting. These maintenance-free blowers feature a rapidly rotating impeller inside a housing with ring-shaped side channels. The impeller draws in air through the inlet, accelerates it within the housing, and expels it through the outlet after pressurization. Single-stage blowers complete one rotation inside the housing, resulting in higher volume flow.

Single Stage Series (VASF Basic/VASF/SV/VARIAIR SV)

Double Stage Series (VASF Basic/VASF/SV/VARIAIR SV)

6. Radial Vacuum Pumps

Radial blowers are engineered to handle high delivery volumes, with their volume flow easily customized to meet customer needs through the integrated frequency inverter on the motor. Featuring a fast and contactless rotating impeller, radial blowers require minimal maintenance and are wear-free.
