About this item
Product details
Customers talk about flow, they want the water out of the bilge, and fast. 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. We have true electromagnetic suppression (emc) and 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.

Great pump
I have been using Rule pumps for 40 years. I've never had a problem with them. The one I just replaced lasted twenty years and i'm good with that
