Hypro D1304B/1504B Diaphragm Kit
Hypro part # 9910-Kit1734 is the replacement diaphragm kit for the Hypro D1504 and D1304 diaphragm pumps.
A visual indication that a diaphragm rebuild is needed is the pump oil will turn a milky color. Prolonged operation with bad diaphragms can cause inter pump problems. We recommend using Hypro pump oil (2160-0038) when rebuilding the D1504 and D1304 pumps.
