Taco 0013-F3 Hydronic Circulating Pump with Flange Connection

Taco 0013-F3 is a cast-iron, 1/6‑hp hydronic cartridge circulator with flange connections, designed for high‑head, medium‑flow service in large residential and light commercial heating, radiant systems, and indirect water heaters. It runs on 115 V AC (single‑phase) and operates at about 3250 rpm, delivering up to 34 gpm against a maximum of 33 ft of head, with a 150 psi maximum system pressure. The flange‑style model accepts 3/4", 1", 1-1/4", or 1-1/2" flanges and ships with flange gaskets; the impeller is non‑metallic and the bearing is carbon. Measured dimensions are roughly 7-1/2 inches long and about 6-1/2 inches high, with a water operating range of 40 to 230°F (4–110°C). Typical applications include hydronic heating loops, radiant floor circuits, and cooling or hydro‑air setups where space is limited but higher head is required, and it serves as a direct replacement in many 13‑series Taco installations due to its flange orientation and multiple inlet sizes.
