Hypro D1064 Diaphragm Kit
Diaphragm kit 9910-Kit2480 includes all parts needed to replace diaphragms on the Hypro D1064 pump. Hypro recommends changing diaphragms every 500 hours or three months, whichever comes first. If your oil has turned a milky color you may have broken diaphragms.
9910-Kit2480 includes four Desmopan diaphragms (9910-1040080), one accumulator diaphragm (9910-1800300) and eight valve o-rings (9910-770571).
When replacing diaphragms follow all factory torque specifications. Diaphragm replacement will require new pump oil. Replace with 3.0 weight non-detergent or Hypro pump oil (2160-0038)
Other rebuild kits available for the D1064 are the valve kit (9910-Kit1964) and o-ring kit (9910-Kit2378).
