Part # AR43261 is the replacement diaphragm kit for the AR250, AR215 and AR280 diaphragm pumps. AR recommends changing the diaphragms every 500 hours or three months, whichever comes first.

Part # AR43261 replaces 9910-KIT1722 and will also rebuild the older Hypro D250 pump. 

The kit includes six replacement Desmopan diaphragms, twelve 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.
