Gianneschi JET-4RB-24V Bronze 24V Jet Pump
The Gianneschi JET-4RB-24V is a bronze, self-priming jet pump built for boat owners and system installers who need dependable water pressure without the guesswork. Running on a 24V DC motor rated at 0.85 kW (1.1 HP) and spinning at 2900 RPM, this pump pulls double duty across fresh water, seawater, and diesel oil applications, making it a practical choice anywhere a compact, corrosion-resistant pump is needed rather than just on a boat.
Inside, the pump pairs a brass impeller with a 316 stainless steel shaft and a bronze body, giving it the kind of resistance to saltwater and general wear that keeps replacement cycles far apart. A polycarbonate diffuser and venturi work alongside a ceramic-NBR mechanical seal to keep the unit sealed and self-priming to a depth of 8 meters (25 feet), while Class F insulation and IP22 protection allow it to hold up in the humid, vibration-prone environments typical of engine rooms and utility spaces.
Whether it's feeding a sanitary system, powering deck wash-down, supplying a fire-fighting line, or simply keeping water pressure steady on demand, the JET-4RB-24V is engineered to run quietly in the background. Installers appreciate that it's straightforward to mount, ground, and connect, and operators appreciate that it just keeps working.

FAQ Section
Q: Can the JET-4RB-24V be used with liquids other than water?
A: Yes, it is rated for fresh water, seawater, diesel oil, and other non-inflammable liquids that are free of suspended solids. It is not suitable for flammable fluids or explosion-hazard environments.
Q: Does this pump need to be primed manually before first use?
A: The pump is self-priming, but if the suction hose has sat unused for a long period or is being started for the first time, water should be run through the line to help the pump achieve the suction needed to self-prime.
Q: What kind of maintenance access should I plan for?
A: A three-piece pipe union is recommended at both the suction and discharge ports so the pump can be disconnected easily for servicing without disturbing the surrounding plumbing.
Q: Where should this pump be installed?
A: It should be mounted in a dry, well-ventilated space with a maximum ambient temperature of 40°C, set on a solid, level surface with the feet down, and secured with bolts and vibration dampers to reduce noise and movement.
Q: Is this pump limited to marine use only?
A: While it's built to marine standards for corrosion resistance, its bronze construction and clean-liquid handling make it suitable for other pressure-boosting or water-transfer applications outside of boats as well.
