Rule 500GPH Electronic Sensing Bilge Pump - 24V for Automatic Water Removal

500GPH Electronic Sensing Bilge Pump - 24V

In the next generation sensing bilge pumps, the 500GPH 24V 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 500GPH Electronic Sensing Bilge Pump (Part Number: 25SA-24) is a compact, reliable solution designed for automatic bilge water management. Utilizing an innovative impeller resistance sensing technology, this pump periodically checks for water every 2-1/2 minutes, activating only when water is detected. This feature ensures efficient operation while conserving power, making it ideal for extended use in marine environments. Its intelligent sensing eliminates the need for a float switch, simplifying installation and reducing potential failure points.

Constructed with durability and safety in mind, the Rule 25SA-24 is fully submersible and ignition protected. It features a stainless-steel shaft for corrosion resistance and a high-efficiency, low-amperage motor that delivers up to 500 gallons per hour. The pump includes a check valve with a hidden air vent to prevent airlocking and a built-in thermal cell that safeguards against overheating, protecting both the pump and your vessel. Additionally, the backflow preventer ensures water flows in the correct direction, enhancing system reliability.

This size-efficient automatic bilge pump is among the smallest available, providing a space-saving solution without compromising performance. Its electromagnetic suppression (EMC) minimizes electrical interference, ensuring stable operation even in complex electronic environments. Whether used in boats, RVs, or other watercraft, the Rule 25SA-24 offers a maintenance-free, automatic operation with manual override capabilities, delivering dependable water removal under a variety of conditions.

Features:

• Completely automatic operation with manual override – no float switch needed

• Submersible and ignition protected for safety and durability

• High efficiency, low amperage motor for extended use

• Stainless-steel shaft for corrosion resistance

• Includes backflow preventer to prevent water backflow
