Kappa-120/150 Diaphragm Kit - 8700.22
Udor part # 8700.22 is the replacement diaphragm kit for the Kappa-120 and Kappa-150 diaphragm pumps. Udor recommends replacing the pump diaphragms after 500 hours of use. When diaphragms rupture the pump oil will turn a milky color for oil and spraying solution mixing.
This kit includes four replacement Desmopan diaphragms (0903.34), one accumulator diaphragm (0903.16) and eight replacement valve o-rings (1101.01).
When replacing the pump diaphragms be sure to follow all factory torque specifications. The accumulator diaphragm should be set to 20% of the pump operating pressure. Replacing pump diaphragms will require the oil to be replaced with 30 weight non-detergent. Udor lube is available using part number 15.5823. The Kappa-120/150 require 84oz of oil.
