Electronic circulator pump ALPHA1 L 25-60 130mm 1x230V 50Hz 6H. ALPHA1 L, the universal circulation pump for Grundfos boiler parts, is the only replacement and renewal pump that fits 95% of boilers equipped with Grundfos pumps.
ALPHA1 L 25-60 130 Grundfos ALPHA1 L 25-60 130 is a high efficiency circulator pump with permanent magnet motor (ECM technology).
The pump offers three control modes, radiator heating, underfloor heating mode and constant speed/curve mode.
In addition, the speed can be controlled by a low voltage PWM (Pulse Width Modulation) signal.
< br>The pump has ceramic shaft and radial bearings, carbon thrust bearing, stainless steel rotor sleeve, support plate and rotor liner, and composite impeller, all of which contribute to long life, and the The pump is self-bleeding, which contributes to simple commissioning and easy control mode selection.
Its compact design, featuring a pump head with a control box and control panel, integrated control, adapts to the most common installations, as well as boilers.
Pump and motor form an integral unit without closure. The pump design is wet rotor. The bearings are therefore lubricated by the pumped liquid. This construction ensures maintenance-free operation.
The pump casing is made of cast iron and is galvanized to improve corrosion resistance.
The motor is a synchronous rotor motor. permanent magnets/compact stator. The pump controller is incorporated in the control box, which is mounted on the stator housing and connected to the stator via terminal connector.
ALPHA1 L Features:
- Three constant/speed curves constant
- Radiator heating mode
- Underfloor heating mode
- PWM profile for heating applications (profile A).
- The PWM signal is a method of generating an analog signal using a digital source.
- With its optimal energy consumption, it complies with the ErP Directive.
- Release screw, accessible from the front of the control box
- Reliable and efficient operation even in the most demanding conditions
- Adjustable and flexible installer connector, with two possible press positions for cable passage
