SEAFLO 12V 2.7GPM 17PSI Water Pressure Pump 41 Series Marine RV

Low-pressure on-demand water supply

A 12V self-priming diaphragm pump delivering up to 2.7GPM at open flow with a 17PSI pressure-switch cut-off. It is intended for low-pressure freshwater or seawater supply systems on boats, caravans and RVs and can serve up to three modest fixtures where 17PSI is suitable.

Technical specifications

Applications and compatibility

• For low-pressure galley, washbasin, deck-rinse or general water transfer systems on 12V boats, caravans and RVs.
• The manufacturer rates the 41 Series short pump for up to three fixtures, subject to demand and plumbing layout.
• 17PSI is substantially lower than many domestic-style pressure systems; confirm tap, heater and appliance requirements before ordering.
• Not intended for petrol, diesel, solvents or other flammable liquids.

Installation and package contents

• Mount dry on a rigid surface using the rubber feet, with ventilation and service access around the motor.
• Fit an inlet strainer, use reinforced potable/marine hose as applicable and keep suction lines airtight.
• Wire through an appropriately rated fuse and switch; the on-demand pressure switch then starts and stops the pump as outlets open and close.
• Package contains one SEAFLO 41 Series pump. Confirm whether the required strainer and exact port adapters are present in the supplied pack before installation.

Frequently asked questions

Will it provide domestic-style high pressure?

No. Its pressure-switch cut-off is 17PSI, intended for lower-pressure systems.

Can it run a shower?

It may supply a low-pressure shower, but available flow and pressure depend on the plumbing and simultaneous fixture demand.

Can it pump seawater?

Yes. SEAFLO lists the 41 Series for fresh and salt water; flush with fresh water after seawater use where practical.

Can it run dry continuously?

No. Short dry-run capability protects against brief loss of supply, but continuous dry running should be avoided.
