Gianneschi IDROMINI ACB80E-12V Bronze 12V Water Pressure System
The Gianneschi IDROMINI ACB80E-12V water pressure system is a fully assembled, ready-to-install pump package designed to deliver consistent, hammer-free water pressure throughout a boat's plumbing. Built with a bronze self-priming centrifugal pump and a star-shaped impeller, it's constructed to hold up against the corrosive demands of marine use while providing smooth, quiet operation at the tap.
What sets this system apart is how complete it is out of the box. Rather than sourcing a pump, tank, gauge, and switch separately, everything arrives pre-assembled and pressure-tested: a 5-liter membrane accumulator tank, an automatic pressure switch, a pressure gauge for at-a-glance monitoring, and a check valve to prevent backflow. That membrane tank does more than just store water — it cushions the sudden pressure spikes that cause water hammer, protecting fittings and extending the life of the plumbing system as a whole.
Owners refitting an older vessel or fitting out a new build will appreciate the combination of a bronze pump body, brass alloy impeller, and AISI 316 stainless steel shaft, materials selected for long-term reliability in wet, salty environments. With a compact footprint of about 5.3 x 6.7 x 16.2 inches, the ACB80E-12V tucks into tight utility spaces while still delivering up to 13.2 GPM at 44 PSI, enough capacity to comfortably run a shower and galley faucet without a noticeable pressure drop.

FAQs
Q: Can the IDROMINI ACB80E-12V run multiple fixtures at the same time?
A: Yes, its 13.2 GPM output and 5-liter accumulator tank are sized to support simultaneous use of a shower and a galley faucet without a significant drop in pressure.
Q: Does this pump require a separate accumulator tank?
A: No, the 5-liter membrane tank is already built into the assembled unit, so no additional tank purchase or installation is needed.
Q: Is the ACB80E-12V suitable for saltwater environments?
A: Yes, the bronze pump body, brass alloy impeller, and AISI 316 stainless steel shaft are specifically chosen to resist corrosion in marine and saltwater conditions.
Q: What causes the pump to turn on and off automatically?
A: An integrated pressure switch monitors system pressure and cycles the pump on and off at factory-set cut-in and cut-out points to maintain consistent flow.
Q: What size plumbing connections does this system use?
A: The unit uses a 3/4 inch inlet and a 1 inch outlet, compatible with standard marine freshwater plumbing.
