The Grundfos UPS 26-150 is a canned rotor type pump, meaning the pump and motor form an integral unit without a shaft seal and with only two gaskets for sealing. This unit's cast iron construction is intended for closed loop applications only, such as fan coils, solar, baseboard heating and radiant heating. Multiple speeds of this circulator pump allow it to match the system's demands with ease, resulting in optimal performance without compromising on comfort.
