TACO 0012-SF4 Stainless Circulator
This TACO 0012-SF4 is a stainless steel circulating pump built for potable water systems. It suits residential or light commercial hydronic installations that need reliable fluid movement. The unit operates on 115V AC single-phase power with a 1/8 hp motor. Its learning thermostat capability helps match output to system demand.
Upgrading from older fixed-speed pumps
The pump replaces fixed-speed circulators that run constantly at one rate. The jump is worth it when you want the motor to adapt its operation based on system conditions. At 1 foot of head it delivers 50 gpm, at 5 feet it delivers 39 gpm, and at 10 feet it delivers 24 gpm. Maximum head is 15 feet where flow reaches 0 gpm.
Flanged installation with common pitfalls
Flanged connections simplify mounting to compatible pipework in 3/4, 1, 11/4, or 11/2 inch sizes. The face-to-face dimension is 8 1/2 inches. Ensure flanges are aligned and gaskets seated to prevent leaks. Verify the system voltage matches 115V AC before wiring. Incorrect pipe sizing or debris in the line can reduce the rated flow performance.
