Rule Automatic Bilge Pump 1100GPH 12V or 24V

Next generation compact submersible 1100 GPH Automatic Sensing electric bilge pump - no float switch required.

Totally submersible pump with water cooled, ignition and TCO protected motor, stainless steel shaft and snap-on strainer base.

These pumps are extremely efficient, offering draw low current and offers high capacity output in a very compact housing, to fit into the smallest available space.

This automatic pump will consume 0.20 amps per day. Please note that using the included check valve will reduce the output flow of the pump. 

How the Automatic Sensing pumps work: The “S” series Automatic sensing RULE bilge pumps work on the principle of impeller resistance. They DON'T need a float switch - they are fully Automatic sensing pumps. The pump turns on every 2 1/2 minutes for about 1 second to sense for water. If water is present, the 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.

Features:

• Fully submersible pump
• 1100 US gallons per hour / 69 litres per minute
• 12 or 24 volt DC only - Cannot be run through 240v transformers
• Higher flow - optimised impeller to provide greater flow at the same amperage as previous model
• High efficiency, low amp draw ignition protected motor includes true Electromagnetic suppression (EMC)
• 16-gauge tin coated copper electrical wiring with silicone infused water blocking feature - to stop water wicking down inside the wiring
• In-built thermal cut-out (TCO) in the motor provides additionalprotection for pump & vessel
• Backflow prevention - now includes a removable check valve in thedischarge nozzle which reduces the amount of water draining back from the pump discharge hose into the bilge.
• Threaded discharge port - gives easier installation and maintenance.
• Discharge hose port is included with each pump
• Hidden air vents in the pump prevent air locking in challenging plumbing installations and helps with the check valve operation
