20559 DOAV502 and DAAV505 Service Kit


The 20559 is a kit to service and replace worn parts on a DOAV502 or DAAV505-L. It should be used whenever the pump's capacity to pull flow is significantly decreased or when replacing the pump's diaphragm. Typically, the 20559 service kit and the 20560 replacement diaphragm are used at the same time to replace all worn parts.
