20560 DOAV502 and DAAV505 Replacement Diaphragm

Overview

The diaphragm of a DOAV502 or DAAV505-L pump is a part that becomes worn over time. If a substantial change in airflow is observed, it is likely that the diaphragm needs to be replaced. When replacing the diaphragm, Campbell Scientific recommends also using new parts from the 20559 DOAV502A and DAAV505 Service Kit.
