Mayer GPA 25-5 circulation pump

The Mayer GPA 25-5 is a next-generation circulation pump designed for heating systems in private homes, apartments, and small commercial spaces. It features precise electronic control, low energy consumption, and optimized hydraulics, ensuring stable heat-carrier circulation under all operating conditions.

The model is equipped with a latest-generation ECM motor that automatically adapts its operation to the system’s actual parameters, maintaining stable pressure and even flow distribution. This results in higher heating efficiency, reduced load on the boiler, and lower heat losses.

The pump includes an LED display showing current power consumption and operating parameters, significantly simplifying diagnostics, adjustments, and scheduled maintenance. The intelligent AUTO mode analyzes system resistance and automatically selects the optimal rotation speed to save energy and enhance accuracy.

The durable cast-iron housing provides high resistance to corrosion, temperature fluctuations, and mechanical stress. Class H electrical insulation and IP42 protection ensure safe operation in high-humidity environments, while the wide heat-carrier temperature range allows the pump to be used for both heating and water-based cooling.
