This is a flexible coupling element for large Edwards E1/E2M series pumps. It cross-references to Edwards part number CUP0041. This is the rubber or plastic insert that connects the motor to the pump. It absorbs shock and handles minor shaft misalignment. Fits E1M175, E1M275, E2M175, and E2M275 models.
It is a specialized filter element used inside the oil system of E1M175 and E2M175 rotary vane pumps. It acts as a strainer to keep contaminants out of the oil flow. If you are doing a major overhaul, this is the correct OEM part.
