Replacement diaphragm (last frame) for the Precision Controls Chem Flow (CF) Series metering pump. Compatible with all CF models — CF07, CF15, and CF30, in both 115V (V1) and 230V (V2) configurations. This is the wear component that flexes with every pump stroke; replacing it restores full output and pressure on a pump that's lost prime, is under-dosing, or is leaking at the pump head. Show more
