Dry pumping keeps sealing oil out of the compression chamber. Gearboxes and bearings may still require lubrication, and process-side filters and separators may still be needed.

For food applications, review moisture, particles, cleaning chemicals and exhaust routing. Match the pump and protective components to the process hygiene plan rather than assuming that an oil-free chamber certifies the entire system.
