Self Priming - A self priming pump is placed higher than the water and is able to draw the water without the need to flood the intake line. Non-Self Priming - These pumps are unable to draw water by themselves and therefore must either be placed below the water level so that the water drains to the pump or if the pump is placed above the water level must have a check valve in order to hold the water in the intake line when and if the pump is shut down.
Despite this downside, when installed properly, external pumps have a longer lifespan than their submersible counterparts, are easy to repair and usually handle gallons of water per hour or above.
The only thing to pay attention to is the self-priming feature. These water pumps are powered by electricity and are either submersible or external.

The pump has a capacity of gallons per hour, is suitable for a wide range of applications and perfect for outdoor or indoor fountains. One of the main features of the pump is the water flow control. The flow is easy to adjust from a knob, allowing you to set the pressure you want.
The maximum flow rate is GPH, which is more than enough for most applications. Another great feature is the presence of four suction cups at the bottom of the pump. These cups keep the pump in place and it is easy to stick on glass or other smooth surfaces, either vertically or horizontally. This allows you to hide the pump among plants to enhance the design.
As filters become dirtier or clogged, less water can pass through them, increasing the pressure. You may decide to use separate pumps for your filter and water features. Filters need to run all day, but you might want more freedom to turn off a water feature. Using separate pumps can save you in energy costs, give you more flexibility, and help to keep water features and filters working well. I have 2-gold fish ponds approx.
