Wet rotor circulation pump ALPHA2 25-40 N 180 1x230V 50Hz 6H 99411365

The ALPHA2 circulation pump is an advanced solution for efficient water circulation in heating, air conditioning, and domestic hot water systems. Equipped with an energy-saving motor and intelligent control functions, it provides optimal performance and user comfort. The high-quality stainless steel construction guarantees durability and corrosion resistance, making it a reliable element of the installation.

Characteristics and application

The ALPHA2 pump is designed to work with systems with constant or variable flow, underfloor heating, and domestic hot water recirculation systems. Its versatility allows it to be used in single-family homes, multi-family buildings, and commercial facilities. The connection length of 180 mm simplifies installation in most standard installations. The ability to adjust the rotational speed allows you to adapt the pump's performance to current needs, which translates into energy savings.

Advantages and benefits

• High energy efficiency: An energy efficiency index (EEI) of 0.15 places the ALPHA2 pump at the forefront of energy-saving devices on the market. This translates into real savings on electricity bills.
• Intelligent control: The AUTOADAPT function automatically selects optimal pump operating parameters, ensuring maximum efficiency and user comfort without the need for manual adjustment.
• Durable construction: The pump body made of stainless steel (grade 304 – 1.4308) provides corrosion resistance and long device life, even in harsh operating conditions.
• Easy installation and operation: The innovative plug simplifies electrical connection, and the intuitive LED display informs about current power consumption and any failures.
• Dry-running protection: The built-in protection prevents the pump from being damaged in the event of a lack of medium flow, which increases its reliability and lifespan.
• Wide range of applications: The pump works perfectly both in new installations and in the modernization of existing heating systems.
• Low noise level: The pump operation is quiet and discreet, ensuring comfortable use even in living spaces (noise level below 43 dB(A)).

The ALPHA2 pump offers a nominal flow rate (BEP) of 1.5 m³/h, a maximum capacity of 2.4 m³/h, and a head (BEP) of 19.71 kPa, and a maximum head of 4 m. It consumes 0.018 kW of power at a supply voltage of 230 V and a frequency of 50/60 Hz. It is designed to operate with a medium temperature from 2 to 110 °C and a working pressure of up to 10 bar. It has a connection with a diameter of 1 1/2 inches (40 mm).

The ALPHA2 pump is an investment in the comfort, savings, and reliability of the heating system. Its advanced features and solid construction guarantee long-term and trouble-free use for both professional installers and end users.
