1-1/2" Stainless Steel Circulator, 1/25 HP

Taco 007-SF5 Stainless Steel Circulator – Reliable Performance for Hydronic and Domestic Recirculation Applications

The Taco 007-SF5 is a stainless steel, wet-rotor circulator pump engineered for closed-loop hydronic systems and domestic hot water recirculation. This model combines the proven hydraulic performance of the standard 007 with the corrosion resistance required for open or potable water systems. Its compact size, quiet operation, and serviceable cartridge design make it a field-proven choice for contractors looking to meet code and reliability standards.

Designed with universal flanges and low power draw, the 007-SF5 integrates easily into residential or light commercial systems where stainless steel construction is required. Suitable for use in both closed heating loops and open recirculation systems, it is a versatile tool in any system designer’s specification.
