Repair numerous essential diaphragm pumps with the help of this handy kit. Six valve assemblies are included (part 9910-1889050) along with six O-rings (part 9910-1140450). Many different hydro pump operations depend on having valves, O-rings, and other components in perfect working order; handy replacement parts allow users to prevent costly breakdowns and delays with instant repairs. Have kits on hand for common maintenance tasks.

Hypro/Pentair is no longer distributing the 9910 series of diaphragm pumps, components, and related parts. Products with Hypro labeling will be unavailable soon.

The 9910-KIT2388 is the standard check valve repair kit for the Hypro D303 and D403 diaphragm pumps. The kit Includes a full set of check valve assemblies and the o-rings for the seat of the valve. If your pump is not drawing water or the flow is irregular your valves may need to be replaced. If your pump is in constant use, we recommend changing these parts out every 3 months or 500 hours of operation.
