AR 70 Diaphragm Kit - AR43241

Part # AR43241 is the replacement diaphragm kit for the AR70 diaphragm pump. AR recommends changing the diaphragms every 500 hours or three months, whichever comes first. Part # AR43241 replaces 9910-Kit1720 and will also rebuild the older Hypro D70 pump.  The kit includes two replacement Desmopan diaphragms, four replacement valve o-rings and replacement accumulator diaphragm. When rebuilding the pump diaphragms follow all factory torque specifications. Accumulator diaphragm should be set to 20% of pump operating pressure. Replacing diaphragms will require new oil. Replace with 30 weight non-detergent.
