Next generation Rule automatic bilge pump. Compact submersible 500 GPH Automatic Sensing electric bilge pump - no float switch required.
How the Automatic Sensing bilge pump work - The “S” series automatic sensing RULE bilge pumps work on the principle of impeller resistance. The bilge pump turns on every 2 1/2 minutes for about 1 second to sense for water. If water is present, the bilge pump will sense resistance at the impeller and continue to run until water is removed. After that it will resume checking for water every 2 1/2 minutes. Water level is kept between 1/8” 3mm low and 3/8’ 10mm high.
