Grundfos UPM3 Perfect for Water Underfloor Heating Circulation Pump

Grundfos UPM3 Perfect for Water Underfloor Heating Circulation Pump Description

Overview UPM3 FLEX AS is a flexible solution for boiler systems now and in the future. It is designed to work both with and without PWM signal, allowing you to upgrade your systems without having to change the circulators. Characteristic Features Glandless High Efficiency circulator for integration in HVAC systems; EEI ≤ 0.20 EN16297/3 Smallest design ever for a circulator; smaller than the well-known UPS circulator Externally controlled signal with standard PWM profile A for 4 MAX Available with many standard and customized housings Active or passive inrush current limitation Ambient temperatures of up to 70 °C. Benefits Lowest space requirements ever for a circulator integrated in an appliance Optimised design fit for easy accessibility Easy access to the user interface from front Easy access to the connectors from front Easy access to the pump head screws from the front Easy access to the de-blocking screw from front Intelligent configuration 5 control modes, 18 curves, PLUS 2 AUTOADAPT proportional and constant pressure Different signals and profiles available (PWM A, PWM C, KMBus) Standard return signal showing power consumption, alarm and operation status Other customized input profiles and different return profiles are possible e.g. flow estimation Ready for Conversion according Ecodesign requirement for August, 2015 exceeding benchmark level; EEI ≤ 0.20 EN16297/3 Unmatched reliability Field and lab tested product quality Ceramic bearing shaft - The UPM3 comes equipped with ceramic bearing shafts for a long and trouble-free lifetime. The ceramic material is extremely durable and will not wear. Double de-blocking system - Electronic de-blocking that maintains the maximum starting torque up to 25 Ncm and manual de-blocking accessible from the front without demounting the control box. High temperature resilience - The resilience to heat will enhance the possibilities of system integration enormously. Ambient temperatures of up to 70 °C.
