Taco 111-8S Series 100 Stainless Steel Pump 1/8 HP

Taco 111-8S Series 100 Stainless Steel

The Taco 111-8S (Series 100) is a stainless steel variation of the legendary Series 100 three-piece circulator. Mechanically, it is engineered for domestic hot water recirculation where a balance of quiet operation and corrosion resistance is required. The stainless steel housing ensures that the pump does not introduce rust into the potable water supply. The mechanical design leverages the classic sleeve-bearing architecture, providing the same smooth, silent flow eye that has made the Series 100 a staple in the plumbing industry for decades.

Driven by a 1/8 HP motor, the 111-8S offers slightly more electrical power than the standard 111-8 to handle the increased demand of large-scale domestic water loops. The motor is precision-aligned to the bearing assembly via a flexible coupling, which dampens electrical hum and prevents shaft vibration. This stable electrical configuration protects the motor windings from the stresses of high-cycle operation, ensuring the unit remains a dependable component of the building’s water delivery system.
