SEAFLO 12V 3.0GPM 60PSI Water Pressure System with 8L Tank

Complete pressure-boost system with accumulator

A 12V five-chamber diaphragm pump assembled with an 8L accumulator tank and pressure gauge to provide smoother, quieter onboard water delivery. The tank stores pressurised water, reduces pump cycling and helps serve up to five outlets where system demand permits.

Technical specifications

Applications and compatibility

• For pressurised freshwater systems on 12V yachts, motorboats, caravans, RVs and remote cabins.
• The accumulator reduces cycling and improves flow stability for taps, showers and similar fixtures.
• Up to five outlets is manufacturer guidance; simultaneous performance depends on demand, pipework and pressure losses.
• Check that every component in the water system is rated for 60PSI.

Installation and package contents

• Mount the assembled system securely in a dry, ventilated service space and support its filled weight.
• Install an inlet strainer, isolation valves and reinforced hose; keep suction plumbing airtight.
• Use correctly sized 12V wiring, a suitable fuse and switching for the 10A maximum load.
• Package contains the pump, 8L accumulator tank, pressure gauge and mounting assembly. Confirm port adapters, strainer and fasteners supplied before ordering.

Frequently asked questions

Why use an accumulator tank?

It stores pressurised water, smooths flow and reduces frequent pump starts.

Can the system supply five outlets at once?

It is designed for systems with up to five outlets, but simultaneous capacity depends on total demand and plumbing losses.

Can it be installed vertically?

Yes. SEAFLO states the assembled system may be mounted horizontally or vertically.

Is the tank pre-charge maintenance-free?

No. Accumulator pre-charge should be checked and adjusted according to the manufacturer instructions with the water side depressurised.
