Circulation pump Mayer GPD 20-35 Z (1300W)

The Mayer GPD 20-35 Z (1300W) is the most powerful pump in the GPD line, equipped with a 1300 W motor designed for systems requiring maximum head, high flow rate, and continuous circulation under heavy load. This model is intended for large facilities, industrial systems, boiler rooms, and long-distance heating mains.

Thanks to its ultra-powerful motor, the pump operates reliably under high pressure differentials, long circuits, and systems with many connected consumers. The “wet” rotor design provides cooling through the pumped liquid, reducing noise, increasing durability, and ensuring stable operation.
