HYDRONIC PUMPS SERIES 821 - 22 gpm - AC ELECTRIC MOTORS

HYDRONIC PUMPS SERIES 821 - 22 gpm - AC ELECTRIC MOTORS

The Ultimate in Reliability in Circulating Pumps for Industrial/Hydronic/Solar Applications.

Depending on application, March hydronic pumps are available in a variety of materials, including plastic, bronze, stainless steel, and cast iron. Specific models are designed to operate with fluid temperatures as high as 350° F (176° C), such as in hot water systems or with hot oil for food products. Special designs can withstand temperatures up to 500° F (260° C).

Models are available for use on 12- and 24-volt DC systems (for uses such as heating systems on public buses) as well as 115- or 230-volt AC systems (popular for use in domestic, industrial and commercial hot water and solar heating applications). Maximum flow rates range from 5.5 GPM (13.7 LPM) to 7.5 GPM (.22 LPM) for DC-powered units, and from 4.5 GPM (13.7 LPM) to 8 GPM (28 LPM) with AC-powered models. Because the motors can be removed without draining the system, service is greatly simplified.

Larger pumps are available with either flange or threaded inlets and outlets.
Note: Pumps are available with 50 or 60 Hertz motors.
