ARO 637396-VV Viton Service Kit for 1 in. Diaphragm Pumps

The ARO 637396-VV is a service kit for the 1" diaphragm pump fluid section, with Viton diaphragms and Viton balls. Going by ARO's notes, you get a diaphragm, a ball, a copper washer, an O-ring, a U-cup, a gasket and a grease package. Pick it for PD10P pumps whose codes end in VV, such as PD10P-FPS-PVV.

Individual parts tied to this kit include the ARO 95989-3 diaphragm, the ARO 93278-3 Viton ball and the ARO Y327-220 and ARO Y327-225 O-rings.

Good Times to Install It

• A PD10P pump begins leaking fluid into its air exhaust.
• Flow has dropped on a pump that otherwise shifts normally.
• You already have the fluid section open and want to renew every seal, washer and gasket in one pass.
• A spare kit on the shelf would shorten downtime for a fleet of PD10P pumps.
