GRUNDFOS CIRCULATOR PUMP ALPHA1 L 25-60 130 ELECTRONIC 1"1/2 UP UPS 15-60 AO

The ALPHA1 L is a high efficiency circulator with permanent magnet motor (ECM technology).

The circulator has 3 control modes: 3 variable pressure curves (heating with radiators), 3 constant pressure curves (underfloor 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, carbon thrust bearing, cast iron pump body, composite impeller, which contribute to increasing the life of the circulator. The pump is self-ventilated.

Easy commissioning, simple control mode selection.

The compact design of the pump head with integrated control box and control panel suits most common installations and installation inside boilers.

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 pumped liquid. These constructions guarantee maintenance-free operation.

The pump body is made of cast iron and is treated by electrolysis to improve corrosion resistance.

The motor is of the synchronous type. The control unit is integrated in the circulator.

Energy optimized, ErP compliant

Release screw, accessible from the front of the control box, works reliably and efficiently even in the toughest conditions
