Rule 500GPH Electronic Sensing Bilge Pump - 12V for Marine and Boat Applications

500GPH Electronic Sensing Bilge Pump - 12V

In the next generation sensing bilge pumps, the 500GPH 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

• 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 500GPH Electronic Sensing Bilge Pump operates on a sophisticated impeller resistance principle, providing reliable automatic water removal without the need for a float switch. Designed for efficiency, this 12V pump periodically checks for water every 2-1/2 minutes by briefly activating for approximately one second. If water is detected within the range of 1/8" to 3/8", the pump continues to run until the bilge is drained, then resumes sensing. This intelligent operation minimizes power consumption and simplifies installation by eliminating float switches. Constructed with a stainless-steel shaft and a high-efficiency, low-amperage motor, it ensures durability and energy savings. The pump includes a check valve with a hidden air vent to prevent airlocking, and it features true electromagnetic interference suppression (EMC) along with a built-in thermal cell for overheating protection, enhancing reliability in demanding marine environments. Its compact size makes it the smallest automatic bilge pump available, ideal for tight spaces on boats and watercraft. The pump is fully submersible and ignition protected, suitable for various marine applications. It also comes equipped with a backflow preventer to ensure water does not return into the bilge. The design prioritizes safety and performance, providing peace of mind during extended boating trips. Please note, this product contains chemicals known to cause reproductive harm in California, and appropriate precautions should be taken during installation and use. Whether for emergency bilge pumping or routine water management, the Rule 500GPH Electronic Sensing Bilge Pump offers a dependable, maintenance-free solution that keeps bilges dry with minimal effort.
