Rule PWC 500 GPH Automatic Bilge Pump – Efficient Self-Priming Marine Pump with Check Valve and Thermal Protection

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 an advanced, compact solution for reliable water removal on boats and marine vessels. Designed with next-generation sensing technology, this pump operates on the principle of impeller resistance, activating every 2-1/2 minutes for about one second to detect water presence. If water is detected within the range of 1/8 inch to 3/8 inch, the pump will automatically run until the bilge is dry, then resume periodic checks, ensuring continuous protection without manual intervention. Its intelligent design allows it to operate efficiently at just 12 volts, making it suitable for standard onboard power supplies, and offers superior performance compared to previous models. The inclusion of check valves and a hidden air vent prevents airlocking, ensuring smooth operation and minimizing maintenance. Equipped with a stainless-steel shaft, the pump boasts high efficiency and low power consumption, making it ideal for extended use. Its completely automatic operation, combined with a manual override, provides versatility for users who need control over the pumping process. Safety features include ignition protection and built-in thermal protection that prevents overheating, safeguarding both the pump and the vessel. The pump also features true electromagnetic interference suppression (EMC), ensuring reliable operation even in electrically noisy environments. Compact and lightweight, the Rule PWC 500 GPH pump is one of the smallest automatic bilge pumps on the market, making it suitable for various installation spaces. Its durable construction and integrated backflow preventer contribute to long-term performance and dependability, giving boat owners peace of mind during all conditions. This pump complies with Prop 65 warnings, alerting users to chemicals that could cause health issues, and emphasizes safety and environmental responsibility. Whether for emergency bilge pumping or routine water management, the Rule PWC 500 GPH Automatic Pump offers a smart, efficient, and maintenance-friendly solution for marine applications.

Features:

• Completely automatic operation with manual override; no float switch required

• Submersible and ignition protected for marine safety

• High efficiency, low amperage motor for energy savings

• Stainless-steel shaft ensures durability and corrosion resistance

• Includes backflow preventer to prevent water reverse flow
