Home water equipment that promises steady pressure for small 12V systems, with components designed for potable use. Peace of mind for owners who need reliable taps and showers while off-grid or on the move. Is the Seaflo 33-Series Water Pump and Accumulator Tank System the right choice for your boat or caravan?
⚡ At a Glance
- • Flow Performance: Delivers 3.0 GPM flow and maintains pressure up to 45 PSI, while drawing up to 8.0A.
- • Best for: Owners of small boats, caravans or motorhomes needing reliable 12V freshwater supply and steady tap pressure.
- • Not ideal for: High-demand household mains replacement or systems requiring very large tank capacity.
12V DC pump rated at 3.0 GPM and 45 PSI, supplied with a 0.2 gallon accumulator tank and fittings. Self-priming and run-dry capable, constructed from materials suitable for drinking water.
Steadier water pressure - thanks to the accumulator tank
A 0.2 gallon accumulator tank stores a small reserve of pressurised water, absorbing pressure spikes and reducing frequent pump starts. Reduced cycling occurs because short demand events draw from the tank rather than restarting the pump each time.
More consistent flow at taps and showers, with fewer on/off cycles that lengthen component life and improve user comfort.
Efficient 12V operation - with a modest 8.0A maximum draw
Designed for 12V DC systems, the pump draws up to 8.0A under load, matching common boat and caravan electrical supplies. Lower current draw reduces strain on batteries compared with higher-draw units.
Suits battery-powered installations, helping preserve battery capacity during typical daily use and keeping run times longer between charges.
Safe for potable use - thanks to drinking-water compatible materials
Components are specified as safe for drinking applications, using materials suitable for contact with potable water. Included strainer helps prevent debris ingress, protecting internal seals and waterways.
Suitable for freshwater taps and onboard systems where hygiene matters, with reduced risk of taste or contamination from unsuitable materials.
