SKU AR43257

Part # AR43257 is the replacement diaphragm kit for the AR160 and AR185 diaphragm pumps. AR recommends changing the diaphragms every 500 hours or three months, whichever comes first.

Part # AR43257 will also rebuild the older Hypro D160 pumps. 

The kit includes four replacement Desmopan diaphragms, eight 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.
