Rule 500GPH Standard Bilge Pump - 24V

500GPH Standard Bilge Pump - 24V Customers talk about flow, they want the water out of the bilge, and fast. Improved design and performance means that our next generation 500GPH pump will produce this flow at just 24V rather than 27.2V 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 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. 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. We've re-engineered the inside and outside of our bilge pumps, starting with a blank slate. And we're just getting started Features: Non-automatic - used with a panel switch or Rule float switch Submersible and Ignition Protected High efficiency, low amp motor Stainless-steel shaft Includes backflow preventer WARNING: 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.
