Rule 1100GPH Electronic Sensing Bilge Pump - 12V | Automatic Submersible Marine Pump with No Float Switch Needed

1100GPH Electronic Sensing Bilge Pump - 12V

In the next generation sensing bilge pumps, the 1100GPH 12V S series pump works on the principle of impeller resistance. 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. After that, it will resume checking for water every 2-1/2 minutes.

Water is kept in check between 1/8" and 3/8"!!! Great idea when power conservation is needed and as an added benefit, no float switch is needed!

All that plus the added benefits of our standard bilge pump:

• Check valve included with hidden air vent to prevent airlocking
  
• True electromagnetic suppression (EMC)
  
• A built-in thermal cell that protects the pump and the vessel when things get too hot

These are the smallest automatic pumps available on the market!!!

Features:

• Completely automatic with manual override - No Float Switch Needed!
  
• Submersible and Ignition Protected
  
• High efficiency, low amp motor
  
• Stainless-steel shaft
  
• Includes backflow preventer

WARNING: This product can expose you to chemicals including 1,3-Butadiene which is known to the State of California to cause cancer, birth defects or other reproductive harm. For more information go to P65Warnings.ca.gov.

The Rule 1100GPH Electronic Sensing Bilge Pump (Part Number: 27SA) is engineered for reliable and energy-efficient water removal in marine applications. Utilizing advanced impeller resistance technology, this 12V pump automatically activates every 2-1/2 minutes to check for water, eliminating the need for a float switch. When water is detected within the range of 1/8" to 3/8", the pump continues operating until the bilge is dry, then automatically pauses and resumes checks, ensuring optimal performance with minimal power consumption. Its compact design makes it one of the smallest automatic bilge pumps available, perfect for tight spaces and efficient marine maintenance. This pump’s features include a check valve with a hidden air vent to prevent airlocking, true electromagnetic suppression (EMC) for interference reduction, and a built-in thermal cell that safeguards against overheating, extending the lifespan of the pump and protecting your vessel. Constructed with a stainless-steel shaft and a high-efficiency, low-amp motor, the Rule 1100GPH pump combines durability and performance. It is fully submersible, ignition protected, and includes a backflow preventer to ensure water doesn’t re-enter the bilge. This maintenance-free pump delivers peace of mind on the water, providing automatic operation and manual override options for flexibility. As with all electronic marine equipment, it’s important to be aware of Proposition 65 warnings related to certain chemicals, including 1,3-Butadiene. Designed for easy installation and dependable operation, the Rule 1100GPH Electronic Sensing Bilge Pump offers an ideal solution for boat owners seeking a compact, automatic bilge pump that combines innovation, safety, and efficiency.
