The Clean & Overhaul Kit is intended for use during routine maintenance of Edwards E2M28 and E2M30 oil‑sealed rotary vane vacuum pumps. This kit contains the seals, gaskets, and service components required to carry out a clean and overhaul service on hydrocarbon‑oil pumps, in accordance with the procedures defined in the relevant instruction manual. A clean and overhaul service restores sealing integrity within the pump following extended operation and is recommended during planned rebuild intervals or when replacing major service components.
