The Pondmaster pump is a magnetically-driven centrifugal water pump. It has no seals to wear and contains no oil, so it's safe for your pond. The Pondmaster pump can be used submerged or inlined. All electrical components are encapsulated in epoxy, and the energy used is approximately 1/2 of regular driven pumps. The pre-filter is provided for use in situations where deposits in the water could clog or damage the pump helping to give you uninterrupted service.
Pondmaster pumps are ideal for any pond application and operate equally well inline or submerged. With only one moving part, a ceramic impeller, ad an epoxy-encased power unit, there's never a fear that it will contaminate the water with harmful oils or chemicals.
