- Compact output is not intended for multiple simultaneous fixtures or high-volume showers.
- Use only with compatible clean-water fluids; do not pump fuel, solvents or flammable liquids.
Installation and package contents
- Mount dry in a ventilated position using vibration-isolating feet and allow access to the pressure switch.
- Install a fine inlet strainer and ensure the suction side is airtight; quick-connect adapters must match the installed tubing.
- Provide correctly sized wiring and circuit protection for the 3.8A maximum draw and cable length.
- Package contains one SEAFLO 23A pressure pump. Port fittings vary by configuration, so verify connector type and tube size before ordering.
Frequently asked questions
Does it switch on automatically?
Yes. The pressure switch starts the pump when system pressure falls and stops it at the set pressure.
Is 1.0GPM available at 40PSI?
No. The stated 1.0GPM is open flow; delivered flow falls as pressure rises.
Can it supply several taps?
It is best suited to a single low-flow outlet because of its compact capacity.
Can it run dry?
It tolerates short dry-run periods, but continuous dry operation should be avoided.
