Applications
Built for the Sta-Rite D-series pump seal service — everything you need to reseal the pump in one kit, instead of sourcing four parts separately. Matching from a worn pump or a parts list? Confirm your pump model and frame from the nameplate before ordering, or send a photo to info@sealhouseusa.com, or call/text 561-414-1046. No purchase required — our seal specialists will match it.

Why Buy the Kit 
Ordering the seal, sleeve, diffuser ring, and gasket together as a kit means every part matches the same pump service, arrives together, and saves you sourcing them one at a time. Prefer to buy a single part? Each is available separately — see the individual product links below.
