The Stuart Pulse Cast Iron Circulator is a high-efficiency, variable speed pump designed for water circulation in heating, air-conditioning, and ventilation systems. Engineered for reliable performance, it continuously monitors system pressure and flow, automatically adjusting operation based on the selected control mode. Featuring advanced ECM permanent magnet technology, the pump offers multiple operating modes including automatic, proportional pressure, constant pressure, and constant speed. An integrated night mode further enhances energy efficiency by reducing operation during low-demand periods. The robust cast iron housing ensures durability, while carbon-graphite bearings provide long service life. Additional features such as automatic venting, built-in protection systems, and an LED display control panel make installation, operation, and maintenance straightforward.
