ALPHA1 vs ALPHA2 (25-60 130): Which to Choose?

When to choose ALPHA1: You want a reliable, affordable replacement with simple operation.
When to choose ALPHA2: You want maximum energy savings (as low as 6W) and automatic optimization.

Why 130mm Flange is the Industry Standard
The 130mm flange distance is found in over 80% of residential heating systems, including:

• Most single-family homes built after 1970

• Standard boiler installations

• Grundfos UPS series pumps

• Taco, Bell & Gossett, Wilo residential circulators

Durability & Reliability
Engineered for continuous operation (24/7/365):

• Stainless steel rotor can – corrosion-resistant

• Ceramic bearings – self-lubricating, wear-resistant (50,000+ hours typical life)

• Thermal overload protection – automatic shutdown prevents dry-running damage

• Manual air purge screw – easy de-airing during installation

• Cast iron housing – durable for decades of service

• IP42 rating – protected against dust and dripping water

• Graphite thrust bearing – reduces friction and wear
