The Seaflo 23A Series Automatic Demand Diaphragm Water Pump is a compact water pump with an internal pressure switch that turns the pump on when a tap is open, and off when the tap is closed.
The Seaflo 23A water pump is an automatic demand pump, meaning it will only run when there is a demand for water. It is equipped with a pressure switch that turns the pump on when the pressure in the water system drops below a certain level and turns it off when the pressure reaches a preset level. The pump uses a diaphragm to create a vacuum that draws water into the pump and then uses another diaphragm to pressurize and discharge the water through the outlet. This design makes the pump self-priming, meaning it can draw water from a tank or other source without the need for manual priming.
