Rule PWC 500 GPH Automatic Bilge Pump with Impeller Resistance Sensing

PWC 500 GPH Automatic Pump

In the next generation sensing bilge pumps, the 500 GPH 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". Improved design and performance means that our new 500 GPH pump will produce this flow at just 12 volts rather than 13.6 volts as previously required, more typical of on board voltage supply. Our next generation of Rule pumps include check valves and to do this we've created a hidden air vent to prevent airlocking. Under each strainer tab there is a small hole that vents any air trapped in the pump housing preventing airlocks. Rule has true electromagnetic suppression (EMC) and have a built-in thermal cell that protects the pump and the vessel when things get too hot. These are the smallest automatic pumps 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 PWC 500 GPH Automatic Bilge Pump is designed for efficient and reliable water removal in various marine applications. Utilizing next-generation impeller resistance sensing technology, this pump automatically activates every 2-1/2 minutes for about one second to check for water presence. If water is detected, it continues running until the bilge is clear, then resumes periodic water checks. This intelligent design ensures your bilge remains dry without manual intervention, maintaining vessel safety and performance. The pump operates effectively at just 12 volts, making it compatible with typical onboard power supplies, and features an improved flow rate to handle substantial water volumes efficiently. Its compact size and advanced features make it one of the smallest automatic bilge pumps on the market, perfect for space-constrained applications. The pump includes a check valve and a hidden air vent to prevent airlocks, ensuring smooth operation and longevity. Built with a stainless-steel shaft and a high-efficiency, low-amp motor, it offers durability and energy savings. Additional safety features include electromagnetic suppression (EMC) and a thermal protection cell to prevent overheating, safeguarding both the pump and your vessel. The pump is fully submersible and ignition protected, suitable for various marine environments. It also includes a backflow preventer to maintain proper water flow and prevent back-siphoning, enhancing operational safety. Whether for bilge pumping or other fluid transfer needs, this pump provides a reliable, maintenance-free solution for boaters seeking automatic water management with minimal hassle. Its compact design, combined with advanced sensing and safety features, ensures ease of installation and long-term dependability in demanding marine conditions.
