Rule 20SA 800 GPH Electronic Sensing Bilge Pump - 12V | Automatic Submersible Marine Pump

800GPH Electronic Sensing Bilge Pump - 12V

In the next generation sensing bilge pumps, the 800GPH 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

The Rule 20SA 800 GPH electronic sensing bilge pump offers reliable, maintenance-free operation for marine applications. Designed with advanced impeller resistance technology, this 12V pump automatically detects water levels between 1/8" and 3/8" without the need for a float switch. It activates every 2-1/2 minutes to check for water, ensuring continuous protection against bilge flooding while conserving power. When water is detected, the pump runs until the bilge is dry, then resumes sensing, making it ideal for efficient water management on boats and vessels.

Constructed for durability and safety, the Rule 20SA features a stainless-steel shaft, high-efficiency low amp motor, and ignition protection, ensuring safe operation even in challenging marine environments. It includes a check valve with a hidden air vent to prevent airlocking and a backflow preventer to stop water from reversing. The built-in thermal switch protects the motor and vessel from overheating, while electromagnetic suppression (EMC) minimizes electrical interference. These compact, automatic bilge pumps are the smallest on the market, providing space-saving installation options without sacrificing performance.

Ideal for boat owners seeking a dependable, easy-to-install bilge pump that requires no float switches, the Rule 20SA combines advanced sensing technology with rugged construction. Whether used in fresh or saltwater, this pump ensures your vessel remains dry and safe, all while conserving power and reducing maintenance. Please note, this product contains chemicals known to the State of California to cause reproductive harm, as detailed in Prop 65 warnings. For more information, visit P65Warnings.ca.gov.
