Product Information :
Parts Page (click here)The Finish Thompson DB22P-21-M270 is a Sealless Magnetic Drive Centrifugal Pump and Motor unit, with Polypropylene Casing and Adapter, a 7.25 inch maximum diameter Polypropylene impeller, Carbon bushing, FKM o-ring, 8-pole magnet set, 2 inch NPT suction and 2 inch NPT discharge ports, and is closed coupled to a 10 Horsepower, 3450 RPM, 60 HZ, 208/230/460 Volt, 3 Phase, TEFC (Totally Enclosed Fan Cooled) 215TC frame Motor. This pump is a flooded suction, sealless magnetic drive centrifugal pump built without a mechanical seal, so there is nothing to leak, maintain or replace. Its casing, impeller and barrier are moulded in Glass Fiber Reinforced Polypropylene, its shaft and thrust rings are High-Purity Alumina Ceramic, and it runs on a Carbon bushing, which lets it run dry for hours without damage. The 7.25 inch maximum diameter Polypropylene impeller is two-piece, so it can be changed without replacing the inner drive, and it is driven through an 8-pole set of neodymium iron boron magnets, encapsulated in unfilled resin and balanced to ISO 1940 G2.5. Liquid enters through the 2 inch NPT suction and leaves through the 2 inch NPT discharge. It is close coupled to a 10 Horsepower, 3450 RPM, 60 HZ, 208/230/460 Volt, 3 Phase, TEFC (Totally Enclosed Fan Cooled) 215TC frame Motor, and the same pump end takes a range of horsepowers, so a heavier liquid is handled by fitting more power rather than a different pump. This size works to 90 psi working pressure, viscosity to 150 cP, specific gravity over 1.8, and liquid temperature to 180 degrees F in this material, at efficiencies up to 70 percent. The design is back pullout, the outer drive is measurement-free to set, and the pump is CE certified.

Applications
The Finish Thompson DB22P21M270 is a Glass Fiber Reinforced Polypropylene sealless magnetic drive centrifugal pump and motor unit for corrosive and aggressive liquids in chemical process, industrial and OEM service.
It is a flooded suction pump, handling liquid temperatures to 180 degrees F, working pressure to 90 psi, viscosity to 150 cP and specific gravity over 1.8, through 2 inch NPT suction and 2 inch NPT discharge ports on a 7.25 inch impeller.
The smallest motor listed for this pump suits liquids lighter than water, such as alcohols and solvents, where the power drawn falls with the specific gravity. Water and heavier liquids want the next motor size up.
The DB Series is flooded suction and does not self prime. A pump that has to lift its liquid, or a line carrying trapped air, wants the selfpriming SP Series instead. For flammable or combustible liquids the nonsparking ring and an explosionproof motor are required.
Typical Applications for the Finish Thompson DB22P21M270 are chemical processing, metal plating and finishing, wastewater treatment, fume scrubbing, electronics manufacturing, OEM equipment supply and pharmaceutical, in mining, paper mills, printing, chillers and DI and high purity water service.
