<B>500GPH Standard Bilge Pump - 12V</B><br><br>Customers talk about flow, they want the water out of the bilge, and<br>fast. Improved design and performance means that our next generation 500GPH pump will produce this flow at just 12V rather than 13.6V as previously required...more typical of on board voltage supply.<br><br>Our next generation of Rule pumps include check valves and to do this, we've created 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...and that's how we do it.<br><br>We have true electromagnetic suppression (EMC). We have a built-in thermal cell that protects the pump and the vessel when things get too hot.<br><br>We've re-engineered the inside and outside of our bilge pumps, starting with a blank slate. And we're just getting started<br><br><B>Features:</B><br><UL><LI>Non-automatic - used with a panel switch or Rule float switch<br><LI>Submersible and Ignition Protected<br><LI>High efficiency, low amp motor<br><LI>Stainless-steel shaft<br><LI>Includes backflow preventer</LI></UL><p><strong>WARNING:</strong> This product can expose you to chemicals including 1,3-Butadiene which is known to the State of California to cause cancer, birth defects or other reproductive harm.
