We provide repair and overhaul services for Busch vacuum pumps and boosters. All pumps are rebuilt at our suburban Chicago location and each leaves with a 90 day warranty. Busch vacuum pumps undergo disassembly, inspection and cleaning as well as total replacement of seals, bearings, vanes, gaskets and o-rings. All other parts are replaced as required for an extra charge. We also complete a test run for 24 hours, thorough draining and cleaning; two or more changes of hydrocarbon oil, painting and final tagging with re-build information. We can help with all your Busch vacuum pumps maintenance and servicing needs.
