Grundfos Alpha Solar primary pump 98989297

Article number 98989297
Installation length 180mm
Type: 25-145
EEI: 0.20

High-efficiency circulation pump ALPHA SOLAR for use in solar heating systems with variable or constant volume flow. However, high-efficiency pumps with electronically commutated motors (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 controller in order to optimize the solar energy yield and the system temperature. This also significantly 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 system.

Versions/Functions/Features:

  • High efficiency EC permanent magnet motor technology
  • Energy Efficiency Index (EEI) ≤ 0.20 according to EN 16297-3: 2012 Best in Class
  • PWM Profile C. The PWM signal is a method of generating an analog signal from a digital source
  • 4 constant speeds
  • Maintenance-free
  • Low noise
  • easy installation
  • Release screw
  • Max. ambient temperature +70°C

In order to install this product, the 230 volt network must be accessed. Work on the 230 volt network may only be carried out by a qualified electrician (according to VDE 0100)!
