The ALPHA1 L is a high efficiency circulator pump with permanent magnet motor (ECM technology). The circulator pump has 3 regulation modes: 3 variable pressure curves (heating with radiators), 3 constant pressure curves (floor heating) and 3 fixed speeds. The speed can be controlled by a low voltage PWM (Pulse Width Modulation) signal. The pump has a ceramic shaft and radial bearings, a carbon thrust bearing, a cast iron pump body, a composite wheel, which help increase the life of the circulator pump. The pump is self-ventilated. Easy commissioning, simple selection of the control mode. The compact design of the pump head with integrated control box and control panel fits most common installations as well as installation inside the boilers. The pump and motor form an integral unit without shaft seal. It is a wet rotor pump. This means that the bearings are lubricated by the fluid being pumped. These constructions ensure maintenance-free operation. The pump body is made of cast iron, it is treated by electrolysis-to improve resistance to corrosion. The motor is of the synchronous type. The control unit is integrated into the circulator pump. Energy optimised, compliant with the ErP directive, Unblocking screw, accessible from the front of the control unit, it functions reliably and efficiently even under the most difficult conditions Insulating shell not supplied Liquid temperature range: 2 ... 95°C Ambient temperature range: 0 ... 55°C
