AR 303/ AR 403 Diaphragm Kit - BlueFlex

SKU AR43289

Part # AR43289 is the BlueFlex diaphragm kit for the AR303 and AR403 diaphragm pumps. This diaphragm kit will also work in the Hypro D403 Pump. When diaphragms rupture the oil in the reservoir will turn a milky color.

BlueFlex diaphragms are reliability new to the industry. The special shape and the thickness of the diaphragms has been carefully optimized to reduce mechanical stresses during the working cycle of the pump, also under the most difficult working conditions. The BlueFlex Material has been tested and shown to outlast standard Desmopan diaphragms. 

The kit includes three BlueFlex diaphragms (800082), six replacement o-rings (1140450) and six replacement o-rings (780050).

When replacing the pump diaphragms be sure to follow all factory torque specifications. A pump rebuild will also require the oil to be drained and replaced with 30-weight non-detergent oil.
