The Meibes Meiflow TOP S RLB DN 25 pump group is designed to protect solid-fuel boilers against low-temperature corrosion. If the return line is too cold, hot water from the flow is blended in via the bypass, helping the boiler reach a safe operating temperature above the dew point more quickly and reducing tar formation and fouling. The set is equipped with a Grundfos Alpha2.1 25-60 circulation pump, a three-way mixing valve with adjustable bypass, a servomotor with integrated temperature control, and two strap-on thermometers integrated into the handles of the ball valves. It also includes a design EPP insulation shell, a wall bracket, and the option to swap the flow and return sides of the pipework.
