As their name implies, External Pond Pumps are designed to be installed outside of the pond, or "in-line". External pond pumps are a better choice for medium to larger ponds. They can handle greater water flows (4,000 to 10,000 GPH) and are less costly to operate. Other benefits of an external pump include ease of maintenance, longer average life, and the ability to replace parts as external pumps are not encased in resin like a submersible pump. On the downside, an external pump takes more time and effort to install, they must be camouflaged from view, and they are generally more expensive than submersible pond pumps.
