Hypro 3430-0332 Repair Kit for 9303 / 9306 Series Centrifugal Pumps – Seal, O-Ring & Gasket (Replaces 2120-0008)

Hypro 3430-0332 repair parts kit for Hypro 9303 and 9306 series hydraulic centrifugal pumps. It contains the mechanical seal, casing O-ring and rubber gasket: the three parts that wear and let a pump weep at the back cover or drip from the slinger. This is the standard annual rebuild kit for a sprayer pump.

Looking for the Hypro 2120-0008 mechanical seal? Hypro no longer sells the 2120-0008 on its own. This 3430-0332 kit is what you order now in its place.

In stock at our Spokane, WA shop. Pumping fertilizer or running the pump hard? Ask about the silicon carbide seal upgrade kit (3430-0589) instead. It outlasts the standard Viton/ceramic seal in abrasive service.
