Pumps come in an array of models and sizes. Pumps are available in both submersible and external (out-of-pond models). For smaller water garden ponds, a submersible pump is the most economical. Larger water gardens and koi ponds are typically better served using an external pump.
It is generally recommended that the water in a pond be turned over roughly once per hour or two, depending on the configuration of the filtration system. However, there are many factors that need to be considered in the selection of pump flow including filtration type, friction and head loss factors, aesthetic features, operating costs, etc.
We have extensive experience in koi pond pumps and filtration systems. Please feel free to contact us should you require assitance with your project.
