Grundfos UPSe and ALPHA 15-58 Circulators

Grundfos UPSe and Alpha 15-58 CirculatorsThe next generation of circulators Grundfos circulators are small- and medium-sized, speedcontrolled, high-efficiency pumps fitted with an electronically commutated motor with permanent-magnet rotor and variable frequency drive. A magnetite-resistant design, robust ceramic shaft, and stainless-steel bearing plate ensure that the pump delivers the optimal system performance at the lowest possible energy consumption reliably throughout the years. UPSe, ALPHA and ALPHA2 feature eight different control modes, designed for certain applications. ALPHA and ALPHA2 also feature AUTOADAPT. The AUTOADAPT function continuously adjusts the pump performance to the actual heat demand, i.e. the size of the system and... Read more
