Gianneschi CG25/12 AE/R Pump 230/400/50 — Bronze Centrifugal Water Pump
The Gianneschi CG25/12 AE/R is a centrifugal water pump built for anyone who needs dependable fluid transfer without constant maintenance headaches. Manufactured in Italy, it pairs a corrosion-resistant bronze body with a three-phase motor rated for 230/400V at 50Hz, giving it the flexibility to run on standard European three-phase power setups. While it's a familiar name on boats and yachts, this pump is just as capable in shore-based settings — think workshops, irrigation setups, cooling loops, and general industrial water handling — anywhere a compact, reliable centrifugal pump is needed.
What sets this pump apart is its straightforward, no-nonsense design. The open impeller keeps things simple and effective for clean to lightly soiled water, and because it's a non self-priming unit, it's meant to be installed below the fluid source so it stays primed and ready to work. Owners appreciate that Gianneschi builds these pumps to be serviceable, with parts and repair kits typically available, so a unit that's been in service for years doesn't have to be replaced outright when something wears out.
Whether it's circulating seawater on a vessel, moving freshwater through a plant, or supporting an air conditioning or cooling system, the CG25/12 AE/R is engineered to handle continuous duty without drama. It's a practical choice for technicians and boat owners alike who want proven Italian engineering behind their water systems.

Frequently Asked Questions
Q: Does the Gianneschi CG25/12 AE/R need to be primed before use?
A: Yes, since it's a non self-priming centrifugal pump, it should be installed below the water source so it stays flooded and ready to operate.
Q: Can this pump run on a single-phase power supply?
A: No, the CG25/12 AE/R is built for three-phase power at 230/400V, so a compatible three-phase electrical connection is required.
Q: Is this pump suitable for pumping saltwater?
A: Yes, the bronze construction is designed to resist corrosion from both saltwater and freshwater use.
Q: What kind of liquids can this pump handle?
A: It's built for clean or slightly dirty water thanks to its open impeller design, and it's not rated for flammable fluids or explosive environments.
