• Permitted media temperature for hot water: 0...85°C
• Maximum operating pressure: 10 bar
• Pump nominal diameter: DN25 (RP 1 / G1½)
• Protection class: IPX4D
• Cable: yes
• Boiler / heat pump (for manufacturer): Master Therm

Control and Operation

• Modes Δp-v (variable differential pressure) and Δp-c (constant differential pressure)
• Support for PWM signals (types 1 and 2) and analogue control 0-10 V
• SSM output for collective fault reporting
• Communication options: LIN and Modbus for integration into control systems

The pump is suitable for installation with a horizontal motor and includes features such as air venting and blockage protection.
