The Taco 0012-MSSF1-IFC is a 3-speed stainless steel circulator pump designed for high-flow, low-head hydronic heating applications including large BTU boilers, primary loops and recirculation systems. Its removable Integral Flow Check prevents gravity flow while the multi-speed switch allows fine tuning to match system conditions. This model is a direct replacement for the Grundfos UPS43-44 3-Speed and is suitable for open, potable water systems.
