Submersible Pumps are meant to be at the deepest part inside of your pond. They can be placed directly in the pond, inside your skimmer, or a pond vault box. Most submersible pumps are meant for smaller ponds ranging in 50-5,000 gallons per hour of circulation. Some submersible pumps like the ShinMaywa Pump or the OASE Profimax pump (pictured below) can also be used to drain your pond when needed. We are partial to the Cyclone line from Apline pumps for our larger commercial (non-swimming) ponds.
*Disclaimer: submersible pumps are not meant for swimming use, for safety reasons swimming pools/ponds you need an above-ground/in-line pump.*
