Grundfos Circulator Pump, Series: UP Series, 6.16 gpm, 5-1/4 ft Maximum Head, 25 W, 115 V AC, 0.23 A, 60 Hz, 1 ph, 145 psi Maximum, 104 deg F Ambient, 6-1/4 in W x 5-7/16 in H
Internally controlled and are designed for systems with variable flow rates, where the pump is internally controlled via a user interface. Speed control can reduce power consumption considerably. Eight different control modes, including constant pressure, AUTOAdapt and proportional pressure - AUTOAdapt: The AUTOAdapt function continuously adjusts the pump performance to the actual heat demand, i.e. the size of the system and the changing heat demand during the year. The function will find the setting that provides optimal comfort with minimal energy consumption. It contributes to fast, safe and easy commissioning. A magnetite resistant design, robust ceramic shaft, and stainless steel bearing plate ensure that the circulator reliably delivers the optimal system performance throughout the years at the lowest possible energy consumption.

The Grundfos CM pump has been created with compactness, flexibility and reliability as its central features. This horizontal multi-stage close-coupled pump is a compact, reliable and quiet pump designed to work in a variety of applications. CM pumps are fitted with mains-operated motors. A Grundfos engineered mechanical shaft seal has been designed to eliminate industry-wide problems with shaft seals sticking where SIC-SIC seal faces are used. The solution builds on both the implementation of a rotation stop on the stationary ring and different surface finishing on both the stationary and rotating rings.

The CRE pump is a CR pump, motor and integrated variable frequency drive. The CRE pump is a system which is able to solve application problems and save energy. The basic CR pump range, which can be applied in almost any industrial solution, is already in itself the broadest range available. Through our modular approach, we have made it even broader. The basic CR pump range is available in four different materials - cast iron, two grades of stainless steel and all-titanium. There are eleven flow sizes, capable of producing up to almost 725 psi pressure and with a variety of shaft seals, rubber materials and supply voltages. Pump parts which are typically vulnerable to difficult liquids or particularly demanding operating conditions can be optimized for their purpose and designed for specific requirements.
