Rotary Vane Pressure/Vacuum Pumps

Oil-Free Combined Pumps

Becker’s oil-less rotary vane pressure/vacuum pumps are similar to other vane pumps. An eccentrically mounted rotor with slots rotates in a cylindrical housing and the precisely fitting sliding vanes move in the slots and separate the individual working chambers. However, these pumps feature unique benefits you will not find with standard vacuum pumps.

Becker pioneered the development of the combined pressure and vacuum pumps when it developed a device called the secondary suction. This secondary inlet port allows a continuous flow of inlet air and lets the compressor operate independently of the vacuum pump. All Becker combined pumps include this design.

These robustly constructed combined pumps are suitable for higher pressure differences in vacuum and/or pressure applications. They can reach an ultimate vacuum level of 18″ Hg and maximum pressure of 9 PSIG simultaneously. This done using a secondary suction port, so when the vacuum level is increased the blast air side is not affected.

Their straightforward construction with single shaft direct drive makes for a robust, long-life rotary vane pump with low operation and maintenance costs.

How to Determine the Cost of a Vacuum Pump

For manufacturers and resellers, calculating the true cost of a vacuum pump before purchasing is often a challenge. We look at the real factors that affect what you’ll pay for a new vacuum solution.

Tips for Custom Vacuum Pump Design

For many applications, a custom vacuum pump design is the best way to get a fit-for-purpose solution that improves efficiency and doesn’t compromise on features. However, the customization is only worthwhile if it meets your specific needs.
