SEAFLO 51 Series 12V 5.5GPM 60PSI Water System 1L Accumulator

Overview

Pre-assembled 12V pressurised-water system combining a five-chamber diaphragm pump, inlet strainer and pre-charged 1L accumulator tank on a mounting board. It provides steady on-demand water flow while the accumulator reduces rapid pump cycling at low demand.

Technical specifications

Applications and compatibility

• For 12V motor yachts, sailing yachts, cruisers, houseboats and workboats supplying multiple galley, basin or shower outlets.
• Also suitable for compatible motorhomes, expedition vehicles and remote cabins with a protected 12V supply.
• SEAFLO states it can supply three or more 13mm outlets and up to five fixtures, subject to pipe losses and simultaneous demand.
• Every hose, tap, calorifier and fitting must be rated above the 60PSI shut-off pressure.
• Not a bilge, fuel, sewage, macerator or drinking-water purification system.

Installation and package contents

• Included: pre-assembled five-chamber pump, inlet strainer, 1L accumulator and mounting board.
• Hoses, adapters, fuse, isolation switch and main power cable are not included unless expressly shown.
• Mount securely in a dry, ventilated, serviceable area and protect the complete system from freezing.
• Use cable and circuit protection sized for the 18A maximum draw and keep voltage drop within the installation manual limit.
• Confirm 1/2in MNPT plumbing, check accumulator pre-charge and flush the water system before use.
• The pump is run-dry capable for normal workloads, but intentional prolonged dry running should be avoided.

Frequently asked questions

Q1. What does the accumulator tank do?
It stores a small pressurised volume, smooths flow and reduces rapid pump cycling during low demand.

Q2. How many outlets can it supply?
SEAFLO states three or more 13mm outlets and up to five fixtures, but actual simultaneous performance depends on plumbing and demand.

Q3. Can it be connected to 24V?
No. This specific system is rated for 12V DC.

Q4. Can it replace a smaller existing pump?
Only after checking the 18A electrical load, 60PSI pressure, 5.5GPM flow, 1/2in MNPT ports, dimensions and the ratings of every connected component.
