The Pondmaster 02523 pump is a magnetically driven centrifugal water pump. It has no seals to wear and contains no oil, so it's safe in your pond. The Pondmaster 02523 pump can be used submerged or inline. All electrical components are encapsulated in epoxy. The energy used is approximately 1/2 of regular driven pumps, and 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 utility 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.
