Kappa 33/43/53 Diaphragm Kit - 8700.45

SKU 8700.45

Part # 8700.45 is the replacement diaphragm kit for the Udor Kappa-33/43/53 diaphragm pumps. Udor recommends replacing the pump diaphragms after 500 hours of use or at season's end, whichever comes first. When diaphragms rupture the oil in the reservoir will turn a milky color.

The kit includes three replacement Desmopan diaphragms (0903.50) and six replacement valve o-rings (1101.27).

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. Udor lube can be purchased along with the pump diaphragm kit using part # 15.5823.

Below are downloadable technical specifications to help when rebuilding your pump.
