Rule 800 GPH Low Voltage Automatic Bilge Pump

RULE 20SA

This next generation water-sensing bilge pump works on the principle of impeller resistance. The pump turns on every 2-1/2 minutes for about one second to sense for water. If water is present, the pump will sense the resistance of the water against the impeller and continue to run until all the water is removed. After that, it will resume checking for water every 2-1/2 minutes. 

Water is kept in check between 1/8" and 3/8"!, with no float switch required

Rule pumps have true electromagnetic suppression (EMC). They have a built-in thermal cell that protects the pump from overheating.
