Grundfos UPM3 Hybrid 25-70 Pump for Pumpstation
UPM3 HYBRID is an OEM high efficient circulator offering flexible solutions for thermal solar systems. It is designed to work both with and without PWM signal, allowing you to upgrade your systems without having to change the controller.
Head height: 7m
Pump length: 180mm
Fitting size: 1 3/4"
CABLES NOT INCLUDED
With PWM Signal:
- Externally speed controlled
- Choice of one of 4 PWM SOLAR Profile C curves
Without PWM Signal:
- Externally speed controlled
- Using the Mini Superseal signal cable connection
- Configured via user interface or pre-set in Grundfos factory
Characteristic Features
- High Efficiency circulator for integration in HVAC SOLAR systems; EEI = 0.20 EN16297/3

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° Celsius.
