Taco 131D Series 100 Stainless Steel Pump 1/3HP 115v

Taco 131D Series 100 Stainless Steel 1/3HP

The Taco 131D is a high-performance three-piece circulator featuring a stainless steel mechanical housing, specifically for open-loop and potable water applications. The “D” designation indicates a configuration optimized for high-volume domestic water recirculation. The mechanical design leverages the classic sleeve-bearing architecture, providing silent operation while the stainless steel volute prevents the oxidation and scaling common in fresh, oxygenated water. Its back pull-out capability allows for easy inspection of the impeller and mechanical seal without disturbing the flanges.

Featuring a 1/3 HP 115V motor, the 131D provides the electrical thrust necessary for multi-unit residential or commercial plumbing systems. The motor is thermally protected and physically isolated from the fluid chamber, preventing radiant heat transfer from degrading the electrical insulation. Consistent rotational synchronization reduces shaft run-out, which preserves the integrity of the carbon-ceramic seal faces and ensures a leak-free interface during the high-cycle demands of large facilities.
