Electronic Sensing Bilge Pumps
Electronic sensing operation on the principle of impeller resistance. Float switches are not required. The pump will turn on every 2-1/2 minutes for about one second to sense for water. If water is present, the pump will sense resistance and continue to run until all water is removed. Thereafter, it will check for water every 2-1/2 minutes. Power use in the checking mode is minimal.
FEATURES AND BENEFITS

Pump operates automatically by sensing for water.
Pump turns on every 2-1/2 minutes to feel for water.
When water is encountered, the pump remains on until water is removed and then the pump shuts down.
Thereafter, it reverts to a 2-1/2 minute sensing mode.
