Taco SKS Series SelfSensing Vertical Split-Coupled In-Line Pumps for Commercial HVAC, Hydronic Heating, Cooling, and Variable Flow Systems
Taco SKS Series SelfSensing Vertical Split-Coupled In-Line Pumps are designed for commercial HVAC, hydronic heating, closed cooling circuits, air conditioning systems, solar, geothermal, and water/glycol applications. Built with an integrated pump and drive package, the SKS Series combines vertical in-line pumping efficiency with advanced variable speed control for large mechanical room and central plant systems.
The SKS Series uses Taco’s SelfSensing ProBalance® technology to make system balancing faster, more accurate, and less dependent on external field devices. In constant flow mode, the pump automatically adjusts speed to maintain a user-defined flow set point. In variable flow mode, the pump adapts to system pressure changes and follows the system resistance curve to meet demand. This allows the SKS Series to serve constant flow chiller and boiler pumps, as well as secondary variable flow pump applications.
Because the SKS Series integrates the pump and variable frequency drive, it helps reduce complex wiring, eliminates the need for remote sensors, and allows the pump to automatically respond to system demand changes. Taco also lists multiple operating modes, including constant flow, constant pressure, flow compensation, and duplex pump alternation, with parallel pumping available through Taco’s Modulating Pump Controller.
The vertical split-coupled construction also supports practical serviceability in commercial systems. Compared with close-coupled layouts, the split-coupled arrangement is better suited for larger pump and motor assemblies where maintenance access, seal service, and long-term uptime are important. With flow performance from 0.1 to 7,998 GPM, head range from 0.1 to 282 feet, standard temperature capability of 250°F, optional temperature capability up to 300°F, standard working pressure of 175 PSIG, optional working pressure of 300 PSIG, horsepower from 1-1/2 to 250 HP, and sizes from 1" to 10", Taco SKS Series pumps are built for large variable flow HVAC and hydronic applications.
