Suction Filter with 19mm barbed inlet and outlet and stainless steel screen (J21-112)
One of the few times we ever recommend a filter on the suction side of a pump is with our diaphragm pumps. Diaphragms are a bit vulnerable to damage from small sharp objects so it is a great idea to install one of our suction filters on any diaphragm pump. This one should be installed in the suction pipe when you have 3/4" or 19mm suction pipe.

Worthwhile addition to protect pump, easy to install and seems to work well
