Flanged Stainless Steel Circulator

The Taco 008-SF6 is a single-speed circulating pump built for potable water systems. It operates on 115V AC single-phase power with a 1/25 hp motor. The stainless steel body accepts flanged connections for 3/4 in, 1 in, 1 1/4 in and 1 1/2 in intake pipe sizes. A face-to-face dimension of 6 3/8 in fits standard flange spacing.

Replaces older fixed-speed circulators

This unit suits installations that need a direct swap for a worn pump with the same flange pattern and voltage. The jump is worth it when the existing housing matches the 6 3/8 in spacing and the system head stays at or below 15 ft. At 10 ft of head the pump delivers 8 gpm; flow drops to 0 gpm at the maximum 15 ft head rating.

Fits hydronic heating and potable water loops

Installers who need a compact, flange-mounted circulator for closed-loop hydronics or domestic hot water recirculation will find the dimensions and voltage compatible. Buyers who want variable-speed control or higher head pressure should look at something else. Systems requiring flow above 14 gpm at low head or operation beyond 15 ft of head are not served by this model.

Questions about this item

What flange-to-flange dimension must the piping allow for the 008-SF6 circulator?

The face-to-face dimension is 6 3/8 in, so the piping must accommodate that exact spacing between flanges.

What wiring step is often missed when installing the 115V AC single-phase circulator?

The motor is single-speed and single-phase at 115V AC; the installer must connect the hot, neutral and ground leads to the correct terminals and verify rotation direction before commissioning.

Which component will need replacement first on the 1/25 hp stainless-steel circulator used in potable systems?

The internal mechanical seal and bearing assembly typically wear before the motor windings, so plan to service or replace the cartridge when flow drops below 8 gpm at 10 ft head.
