SSP40DF Diaphragm and filter kit for DBMX250, DBMX300


This aerator repair kits include a head assembly of diaphragms, check valves, and an air intake filter.  Diaphragms and check valves are working parts that wear out over time.  Air intake filters get dirty and need to be replaced.  You can repair all of our linear pumps and aerators.  Most often, our aerators only require replacement of diaphragms, check valves and air filter.  Actually, check valves, built into the head assembly, come with this diaphragm kit.  You may not even notice them.

Watch this video.  It explains how to replace a diaphragm in a linear aerator.  Most importantly, it shows how to properly align diaphragms with the shuttle.

  • DBMX300

A label on the pump housing has the model number and serial number of your aerator.  Please make sure which model you have before you place your order.
