Gianneschi KJET62203 Repair Kit for the JET622B Pump
If your Gianneschi JET622B pump has started losing pressure, running noisy, or showing signs of wear around the seal and impeller, the KJET62203 repair kit gives you everything needed to bring it back to like-new condition. Rather than replacing the whole pump, this kit lets you rebuild the working end with the exact components Gianneschi engineered it with — so fit, flow, and reliability stay true to factory spec.
Inside the box you'll find the impeller, impeller key, O-ring, diffuser, venturi, circlip, mechanical seal, and splash guard ring, all sized specifically for the 400V, 3-Phase, 50Hz JET622B unit. These are the parts that see the most wear over time from constant cycling and water exposure, so replacing them together in one pass is the most efficient way to restore full performance and head off repeat failures.
Boat owners, marine technicians, and service yards rely on this kit because it removes the guesswork from sourcing individual components separately. Everything arrives matched and ready to install, which keeps downtime low and gets the pressure water system back online quickly.
