Gianneschi ECOJET-2B-24V 24V Bronze Self-Priming Water System Pump
If you're running a 24-volt DC system and need a dependable pump that won't quit on you, the Gianneschi ECOJET-2B-24V is worth a close look. It's a bronze-bodied, self-priming jet pump built around a brass impeller and a 316 stainless steel shaft, so it handles fresh water, seawater, and diesel oil without the corrosion headaches that plague lesser materials. The 0.37 kW (0.5 HP) motor spins at 2900 RPM and is designed to work reliably within a static pressure limit of 8 Bar and a suction depth of up to 8 meters, which covers the vast majority of pressure-system and washdown needs on a boat or in a compact industrial setup.
What makes this pump practical rather than just powerful is how it's meant to be installed. Threaded suction and discharge ports keep plumbing straightforward, and Gianneschi recommends a three-piece union at each connection so maintenance never turns into a wrestling match. Mounted flat, in a dry and ventilated space, with a tight suction line and a strainer ahead of the inlet, this unit is built to run quietly in the background for years rather than demand constant attention.
While it's a natural fit for marine sanitary systems, deck washdown, chain washing, and onboard fire fighting, the same self-priming design and clean-liquid handling make it useful anywhere a compact 24V pressure pump is needed outside of boats too — from remote cabins to mobile equipment running on DC power. It's sold here as the pump and motor unit only, giving you the flexibility to pair it with whatever tank, pressure switch, or control system your setup already uses.

Frequently Asked Questions
Q: Does the Gianneschi ECOJET-2B-24V come with a pressure tank or switch?
A: No, this listing is for the pump and motor unit only. It's designed to be paired separately with a pressure tank, accumulator, or electronic pressure control system based on your setup.
Q: Can this pump handle seawater without corroding?
A: Yes, the bronze body, brass impeller, and 316 stainless steel shaft are all selected specifically for resistance to saltwater corrosion, which is why the pump is rated for both fresh water and seawater use.
Q: What kind of liquids should never be run through this pump?
A: The pump is built for clean, non-flammable liquids without suspended particles. It is not rated for flammable fluids or for use in explosion-hazard environments.
Q: How deep can this pump draw water from?
A: It's rated for a maximum suction depth of 8 meters (25 feet), provided the suction line is airtight and slopes continuously upward toward the pump inlet.
Q: Is this pump only suitable for boats?
A: While it's most commonly used in marine sanitary, washdown, and fire fighting systems, the same 24V self-priming design works well in any application needing a compact, corrosion-resistant DC pressure pump, marine or not.
