Critical Selection and Application Notes
Two reliable methods exist to identify the correct replacement carbon vanes for your Becker vacuum pump:
- Pump Model Cross-Reference: Locate your exact pump model number in the final column of the table. Note that identical size codes may correspond to different part numbers due to variations in rotor slot count—4, 5, or 7 vanes per rotor depending on the pump series and displacement. Always verify the quantity per set matches your pump’s rotor configuration.
- Dimensional Verification: If your pump’s identification plate is missing or illegible, carefully measure the length, width, and thickness (height) of a used but intact carbon vane using a precision caliper. Match these measurements to the dimensions column to find the corresponding part number.
This specification guide covers the full range of Becker dry rotary vane vacuum pump models commonly used in global industrial applications. By referencing this table, maintenance technicians and procurement professionals can quickly and accurately order the exact replacement parts needed to keep their Becker vacuum systems operating at peak efficiency throughout their service life.
