Electronic Automatic Bilge Pumps

Computerized operation on the principle of impeller resistance. Float switches are not required.the pump will turn on every 2½ 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 2½ minutes. Power use in the checking mode is minimal.

Features and Benefits:

• no external switch.
• Pump operates automatically by sensing for water.
• Pump turns on every 2½ minutes to feel for water. When water is encountered the pump remains on until water is removed and then pump shuts down. thereafter it reverts to a 2½ minute sensing mode.
