Gianneschi JET-3B-24V Bronze Self-Priming Jet Pump
If you need a dependable pump that can run on 24 volt DC power and still deliver strong, steady pressure, the Gianneschi JET-3B-24V is built for exactly that job. This self-priming jet pump pairs a rugged bronze body with a brass impeller and a 316 stainless steel shaft, giving it the corrosion resistance needed for demanding environments while keeping performance consistent day after day. At 0.55 kW (0.75 HP) and 2900 RPM, it strikes a practical balance between power and efficiency, making it a solid choice anywhere a compact, low-voltage pump needs to move clean liquids reliably.
What makes this pump especially versatile is that it isn't limited to one type of use. While it's a popular option for boats and yachts moving fresh water or seawater, the same design works just as well in fire-fighting setups, air conditioning water circulation, general water pressure systems, and other applications where a self-priming, 24V DC pump gets the job done. Its polycarbonate diffuser and venturi, combined with a ceramic-NBR mechanical seal, help it handle continuous duty without frequent maintenance headaches.
Installation is straightforward when a few basics are followed: mount it on a solid, level surface in a dry, well-ventilated space, keep the room temperature under 40°C, and make sure the mains supply is properly grounded. With a maximum suction depth of 8 meters and the ability to handle static pressures up to 8 bar, the JET-3B-24V gives installers flexibility without sacrificing reliability, whether it's going into a new build or replacing an aging pump.

FAQ Section
Q: Can the JET-3B-24V run continuously without overheating?
Yes, as long as it's installed in a dry, well-ventilated space with room temperature kept under 40°C, and the voltage supply stays within ±5% of 24V DC, the pump is designed for reliable continuous operation.
Q: What kind of liquids can this pump handle besides water?
Beyond fresh water and seawater, it's rated for diesel oil and other non-inflammable liquids, making it flexible for applications outside typical marine water transfer.
Q: Does this pump need to be primed before first use?
Yes. Since it's self-priming up to 8 meters, water needs to be pumped through the suction hose before first startup or after long periods of disuse to establish proper suction.
Q: What's the difference between this and the 230V version of the JET-3B?
The JET-3B-24V runs on 24 Volts DC, making it suited for battery-powered or low-voltage DC systems, while the 230V version is designed for standard AC mains power, so the choice depends on the power source available at the installation site.
Q: Is any special mounting hardware required for installation?
The pump should be bolted to a solid, level surface with vibration dampers installed to reduce vibration and noise during operation; no other specialized hardware is required beyond standard mounting bolts.
