The Flood pumps now come with our highest recommendation. The Flood line of pumps are high volume magnetic drive waterfall pumps. These are the ultimate in waterfall pumps as they combine high water flow with super energy efficiency. The Anjon Flood pumps WON'T let you down like some other well known and greatly overhyped pumps. These pumps come with a full 2 year warranty and are made to last! With the magnetic drive technology additional savings will add up fast as these pumps consume only 82-192 watts. That is less than 1/3 the power of many other waterfall pump brands. These are the perfect pump for waterfalls, filters, and Ultra-Violet Water Clarifiers. They are designed for continuous operation in even the harshest pond environment.
