Our mission is to be the preferred partner worldwide to original equipment manufacturers (OEM) in the HVAC industry


The UPM2 is designed to substitute the UPS – the world’s most successful circulator range for integration in heating appliances. UPM2 offers hydraulic backward compatibility with existing platforms and covers a very broad range of operation, even down to low meter heads. UPM2 is available in many variants to meet your exact performance requirements.


  • Remote speed controlled high efficiency ECM pump with permanent magnet rotor and frequency converter
  • Cost optimised and high availability – use of existing mass production facilities
  • High reliability – use of existing components and wellknown materials to minimise validation of new components,production processes and equipment
  • Energy optimised by improved hydraulic efficiency
  • Fits in existing boiler ranges – no expanded space requirements,possible use of existing pump housingsand electrical compatibility with existing PWM controllers
  • No ambient temperature constraints (EN60335)
  • Controlled via digital PWM signal
  • PWM feedback signal to system control: power consumption or flow estimation and various alarms such as under-voltage warning, under-voltage stop, locked rotor and confirmation of standby mode
