Grundfos Alpha Solar primary pump 98989299
Item number 98989299
Installation length 130mm
Type: 25-75
EEI: 1930 .20
High-efficiency circulation pump ALPHA SOLAR for use in solar heating systems with variable or constant volume flow. However, high-efficiency pumps with an electronically commutated motor (ECM), such as the ALPHA SOLAR, must not be controlled by an external speed controller that changes or varies the supply voltage.
In order to be able to install this product, an intervention in the 230 volt network must be made. Work on the 230 volt network may only be carried out by a qualified electrician (in accordance with VDE 0100)!

High-efficiency circulation pump ALPHA SOLAR for use in solar heating systems with variable or constant volume flow. However, high-efficiency pumps with an electronically commutated motor (ECM), such as the ALPHA SOLAR, must not be controlled by an external speed controller that changes or varies the supply voltage.
The speed can be controlled via a pulse width modulated signal (PWM signal) supplied by the solar system control in order to optimize the solar energy yield and the system temperature. This also considerably reduces the power consumption of the pump.
If no PWM signal is available, the ALPHA SOLAR can be set to one of 4 constant speeds. The pump is then only switched on and off via the control.
