The high-efficiency ALPHA2 GO circulation pump is fitted with an EC motor/GR ET and is designed for fluid circulation in heating/GR ET and air-conditioning systems. The ALPHA2 GO circulation pump features smart control modes: constant pressure, proportional pressure, constant flow/GR ET and constant curve. Each mode features adjustable setpoints. The AUTOADAPT setting, available for constant pressure/GR ET and proportional pressure modes, eliminates the need to manually select the pump setpoint. The PWM input allows for precise speed control, enabling comprehensive system optimisation. The automatic self-priming capability/GR ET and dry-run protection ensure quiet operation/GR ET and pump reliability. The product features a robust start-up mechanism that reduces the risk of blockages caused by the build-up of dirt, magnetite/GR ET and limescale.
