All 00® series three-speed cartridge circulators include our replaceable cartridge design and an integral flow check (IFC ®) which prevents gravity flow, reduces installation costs and improves system performance. The stainless steel 00® series three-speed cartridge circulators are NSF-61 and 372 listed. Our powerful 0012 three-speed circulator is designed for high-flow/medium head applications in large residential/light commercial hydronic heating or chilled water cooling systems. Its high flow capacity is ideal for primary loops or high flow, high btu applications. We've added a robust switch and knob assembly and a large wiring box to simplify installation. The stainless steel 0012 three-speed is best suited for potable water and hot water recirculation systems. The 0012 three-speed is a direct replacement for the Grundfos UPS43-44 3-speed.
