Discover our Premium High-Efficiency Circulator Pump, engineered with advanced ECM (permanent-magnet motor) technology and a compact design to meet all HVAC requirements. Certified with CE and ROHS, this circulator pump is ideal for gas and electric wall-hung boilers, heat pumps, and Heat Interface Units (HIU) systems. Featuring three control modes—radiator heating, underfloor heating, and constant curve/constant speed—this pump allows precise speed control via a low-voltage PWM signal. Its robust construction, including a ceramic shaft, radial bearings, carbon thrust bearing, stainless-steel rotor can, bearing plate, rotor cladding, and composite impeller, ensures long life and reliable performance. Inspired by leading designs such as Wilo, Grundfos, IRG, and DAB, it is self-venting for easy commissioning and control mode selection.
