Wet rotor circulation pump MAGNA3 25-120 180 1x230V PN10 97924248

Circulation pump – an effective solution for your system

The MAGNA3 25-120 circulation pump is an advanced device designed for circulating water in heating, air conditioning and plumbing systems. It is characterized by high energy efficiency (EEI 0.18) and precise adjustment capabilities, which translates into lower operating costs and user comfort. The pump's construction, based on a cast iron body (Pump body material grade: Cast iron GG 20 (GJL-200)), ensures durability and corrosion resistance, and the built-in motor speed controller allows the performance to be adjusted to current needs.

The MAGNA3 25-120 pump is equipped with a number of communication interfaces, such as EtherNet/IP, Modbus RTU, PROFIBUS, LON/LONWorks, BACnet MS/TP and RS-485 and RS-232. These enable integration with building automation systems (BMS) and remote control of the pump's operation. Additionally, the presence of 0-10 V / 2-10 V and 0-20 mA / 4-20 mA interface signals allows connection of external sensors and controllers. A potential-free switching contact signal increases the possibilities of integration with existing infrastructure.

Construction and application

The MAGNA3 pump has external gas tapered (BSPP) connections with a diameter of 1 1/2 inches (40) on both the inlet and outlet sides, which facilitates installation in existing installations. The connection length is 180 mm, and the maximum head is 12 meters with a nominal flow rate of 5.56 m³/h. The device operates with a voltage of 230V and a frequency of 50/60 Hz. Insulation class F guarantees safe operation in various environmental conditions (ambient temperature: 0 ... 40 °C; average operating temperature: -10 ... 110 °C). The maximum working pressure of the pump is 10 bar.

The MAGNA3 pump is ideal for use in:

• Central heating systems
• Domestic hot water systems
• Air conditioning systems
• Industrial installations requiring precise flow control
• Residential and commercial buildings
