Gianneschi CG25/12E/R KIT Repair Kit – Genuine Recambi for CG25/12 Marine Pumps
Keeping a boat's cooling system running smoothly often comes down to the small parts that wear out first — the seal, the O-rings, and the impeller. The Gianneschi CG25/12E/R KIT is a genuine repair kit built specifically for the CG25/12 line of marine centrifugal pumps, giving boat owners and technicians everything they need to restore pump performance without replacing the entire unit.
This kit is designed around Gianneschi's original engineering specs, so every component fits and seals the way the manufacturer intended. Rebuilding with OEM parts rather than generic substitutes helps prevent premature leaks, shaft wear, or seal failure, which are the most common reasons a centrifugal pump loses pressure or starts running hot. For vessels that depend on consistent water circulation for engine cooling or onboard plumbing, that reliability matters.
Because Gianneschi pumps are used across a wide range of commercial and recreational vessels, this kit is a practical option for scheduled maintenance as well as emergency repairs. It's a straightforward way to extend the service life of an existing CG25/12E/R pump while keeping downtime and repair costs to a minimum.

Frequently Asked Questions
Q: Is the CG25/12E/R KIT compatible with all CG25 series pumps?
This kit is matched specifically to the CG25/12E/R pump model. For other CG25 or CG22 variants, confirm the exact model number before ordering to ensure a correct fit.
Q: What does the Gianneschi repair kit typically include?
Gianneschi rebuild kits for this pump family generally include a mechanical seal, O-ring set, and related sealing hardware needed to restore the pump's original performance.
Q: Can this kit be installed without removing the entire pump from the boat?
In most cases the pump housing needs to be opened to access the seal and impeller area, so partial disassembly is required, though full pump removal isn't always necessary depending on the installation.
Q: How do I know if my pump needs this repair kit instead of a full replacement?
Signs like reduced water flow, visible leaking at the shaft seal, or unusual noise from the pump usually point to a worn seal or impeller, which this kit is designed to address before a full pump replacement becomes necessary.
Q: Are Gianneschi repair kits covered under a manufacturer warranty?
Genuine Gianneschi parts typically carry the original manufacturer's warranty; specific terms can vary, so it's worth confirming coverage details at the time of purchase.
