Use cases & applications
Continuous-Duty Vacuum Systems
In applications like packaging or material handling where vacuum pumps run continuously, this separator ensures efficient separation of liquids and particulates, reducing wear on downstream components and extending pump life.
High-Dust Environments
For woodworking, food processing, or pharmaceutical plants where airborne debris is prevalent, this separator captures contaminants before they reach sensitive equipment, maintaining consistent performance and reducing maintenance intervals.

Facilities operating multiple Busch RA or R5 series pumps can standardise on this separator, simplifying inventory management and reducing downtime by keeping a single separator model on hand for various machines.
Retrofit and Upgrade Projects
When replacing worn or obsolete separators on older Multivac or Noitech packaging machines, this aftermarket unit provides a drop-in fit, restoring original efficiency without the cost of branded replacements.
Frequently asked questions
How do I confirm this separator fits my Busch pump?
Check your pump model against the verified list: RA 0063 F, RA 0100 F, R5/RA/RC 0025, 0063, 0100, and their variants. If your model is not listed, measure the outer diameter (72 mm), largest inner diameter (35 mm), and total height (258 mm) to compare.
What is the filtration rating of this separator?
This separator is a general-purpose separator. The specific micron rating is not provided in the specifications, so it is best suited for bulk liquid and coarse particulate separation rather than fine filtration.
What are the exact dimensions and how do they affect fitment?
The body height is 250 mm, with an additional 8 mm for a total height of 258 mm. Outer diameter is 72 mm, and largest inner diameter is 35 mm. Ensure your housing accommodates these measurements for a proper seal.
Is this separator as good as the original branded version?
This separator is an aftermarket replacement built to the original dimensions and ratings. While not a genuine part, it offers a cost-effective alternative for maintaining performance. We recommend checking compatibility with your specific machine.
How do I install this separator?
Installation typically involves removing the old separator and fitting the new one into the housing. Ensure the O-rings or gaskets are clean and properly seated. Torque to manufacturer specifications if applicable.
