The document is a submittal data sheet for a Solar Pumping Station (SPS-PC) that provides all the necessary components for a closed loop solar water heating system in a single pre-insulated and pre-plumbed module. It features a variable speed circulator to optimize flow and maximize energy gain from the solar collectors. The SPS-PC simplifies installation with just a few connections and includes a variable speed solar differential control, temperature gauges, valves, and other safety equipment to monitor and control the solar system. Specifications are provided for the materials, maximum temperatures, pressure ratings, and dimensions.
