EasyPro offers a variety of external pumps in both non-priming and self-priming styles. External pumps offer several advantages over submersible pumps including reduced energy costs and longer average life span.
Non-priming pumps are best used in flooded suction applications. This means the pump sits below the water level it is pumping. Examples would be alongside of a fish tank or in a pump chamber buried alongside of a pond. These pumps can sit above the water level; however, a check valve must be used on the end of the suction line to keep the pump primed.
Self-priming pumps have the capability of purging some air from the suction line and priming themselves (after filling the pump with water the first time). These pumps can sit above the water level without a check valve in the suction line, however, using a check valve speeds up the priming process and ensures a quick flow when the pump is plugged in. Use this chart to help select which pump is best for your application. Start by finding the feet of head column on the right side of the chart. Look down the numbers under the feet of head in your application to find a pump that provides the amount of water needed.
