Pond Pumps

A water pump head is the pressure that is generated by a water pump, which allows a fountain to run, as well as a waterfall, filter, and any other pond components. The common pumps that are found in most pounds have a centrifugal design. This pump contains an impeller that spins to high speeds which creates pressure by centrifugal force. The pressure then pumps the water to the height that is needed to run your pond features.

The good thing about these kinds of pumps is that the speed of the impeller rotation usually stays constant. The energy and pressure of the water pumps stays pretty much the same. Usually it is broken in two parts, uses the energy to pump more water volume to a lower head, or uses the same energy to pump less water volume to a greater head. If you understand this process then it will be much easier for you to figure out which water pump will work best for your watergarden.

Lets begin with flow pumps and pressure pumps. Many pumps feature a design where they pump a lot of water per hour, but the output decreases sharply when "head" increases. Flow pumps are usually used for waterfalls and streams where a larger mount of water output is needed. Pressure pumps use less rated output than a flow pump. The main difference is that the output doesn't drop off so quickly when the head increases. Which makes a pressure pump easier to use around filters and fountainheads.

When you are deciding on a pound pump you can also choose from having a submersible pump or an external pump. There are a few pumps that can actually be used outside of the pond. In fact most common and affordable units are submersible. The best thing about submersible pumps is that they offer the ease of installation, they are reliable with very low prices and they are energy efficient. The only problem that some people might have with a submersible pump is that they are more visible less accessible than most external pumps.
