Viton diaphragms and Viton balls make the ARO 637375-VV the Viton choice among the 637375 EXP fluid section kits. ARO describes it as a service kit for the 1 1/2" diaphragm pump fluid section.

According to the catalog notes, the kit includes a grease package, a gasket, a U-cup, an O-ring, a ball and a diaphragm. Each pump on its fit list carries VV in its model code, such as PD15A-AAP-FVV and PD15R-ASS-SVV. Choose it when you want to replace the elastomer wear parts of one of these pumps as a set.

When a Rebuild Is Due

• A PD15 pump is pushing liquid out through its exhaust port.
