821, 869, & 830 Circulating Pumps

Circulating pumps for industrial hydronic solar applications. March hydronic pumps are available in a variety of materials, including plastic, bronze, and cast iron. Specific models are designed to operated with fluid temperatures as high as 350F (176C), such as in hot water systems or with hot oil for food products. Max. internal pressure 150psi on metal pumps. Special designs can withstand temperatures up to 500F (260C).

12 and 24 volt DC systems (for uses such as heating systems on public buses) as well as 115 or 230v AC systems (popular for use in domestic, industrial and commercial hot water solar heating applications). 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. Seal-less Magnetic drive. Made in the USA.
