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)!

Notice

Please note that gas and electric appliances require increased mains voltage for proper operation. These appliances are not equipped with a two-pin mains plug. The installation of non-pluggable appliances must be carried out by the respective network operator or a certified specialist company, which can also assist you in obtaining any necessary approval from the relevant network operator for the installation of the appliance.

Shipping information: We ship electrical products exclusively to Germany, France, Poland, Belgium, Austria, Slovenia, Spain and the Netherlands.

Legal guarantee

Harmonised EU legal guarantee notice

Minimum two-year legal guarantee protection for goods sold in the European Union.

Consumers can claim their rights under the legal guarantee of conformity, for example if goods:

  • do not match the description;
  • do not function as intended.

Sellers are liable for any lack of conformity which existed when the goods were delivered, and which becomes apparent within the legal guarantee period. Sellers in such a situation are required to offer:

  • free repair or free replacement;
  • in some cases, a price reduction or full reimbursement.

Some countries have a longer legal guarantee period. For second-hand goods, a shorter period may apply, but not less than one year.

What to do if you receive non-conforming goods:

  1. Contact the seller as soon as possible to report the issue;
  2. Provide proof of purchase, such as a receipt, invoice, or bank statement.

Sellers and producers may also offer commercial guarantees, which apply independently from the legal guarantee. For example, you may see this GARAN label representing a commercial guarantee of durability offered by the producer at no additional cost and covering the entire good.
