Wet rotor circulation pump type ALPHA1 25-40 N 130 1x230 50Hz 6H ALPHA1 series 99199587

Circulation pump ALPHA1 25-40 N 130 is an advanced solution for efficient water circulation in heating systems and domestic hot water systems. Designed by Grundfos, it combines reliability, energy efficiency, and ease of installation. It is an ideal choice for both professional installers and users looking for optimal thermal comfort in their homes.

Characteristics and application

The ALPHA1 pump with a permanent magnet motor works perfectly in installations with variable flow rates, automatically adjusting its operation to current needs. This minimizes energy consumption and ensures optimal operating conditions for the heating system. Its construction based on stainless steel guarantees a long service life and corrosion resistance, especially in hot water systems. It can be used in central heating installations, domestic hot water heating systems, and industrial applications requiring precise flow control.

Advantages and benefits

• High energy efficiency (EEI 0.2): This means significant savings on electricity bills compared to traditional circulation pumps.
• Durable construction: The pump body made of stainless steel and the impeller made of durable composite ensure long-lasting and trouble-free operation.
• Quiet operation (below 43 dB): The pump operates discreetly, without disturbing the comfort of the household.
• Easy installation and operation: Compact dimensions (connection length 130 mm) and an intuitive interface make pump installation and configuration easier.
• Wide operating temperature range (2...110 °C): Allows the pump to be used in various temperature conditions, both in heating systems and domestic hot water systems.
• Speed control: Stepless speed control allows precise adjustment of the pump's performance to current system needs.
• Corrosion resistance: The materials used in production provide high resistance to corrosive agents found in water installations.

The ALPHA1 25-40 N 130 pump is equipped with connections with a diameter of 1 1/2 inches (40 mm) with an external BSPP thread, which facilitates integration with existing hydraulic installations. The maximum head is 4 meters, and the nominal flow rate is 1.5 m³/h - these parameters ensure efficient water circulation even in extensive heating systems. The pump is powered by 230 V / 50 Hz. Insulation class F guarantees safe use.
