Finish Thompson DB11, DB15 and DB22 Series Sealless Mag Drive Pump

The DB Series magnetic drive pump is the new standard for hydraulic efficiency and corrosive fluid handling.

With design-aided magnetic flux and computational fluid dynamics technology, the DB Series packs all the high-pressure, fluid-handling punch you would expect from a Finish Thompson pump.

Born from painstaking, extensive R & D effort, the efficiency of the DB Series lowers energy consumption and operating costs over the long life cycle of the pump.

Constructed from Polypropylene or PVDF, the DB Series operates durably in the most corrosive of environments. It can even run dry without damage.

This rock solid embodiment of technological advancement is superior in precision, performance and reliability to other pumps on the market.

That's why we offer the industry's best five-year warranty. And why everyone else is undoubtedly heading back to the drawing board.
