Circulation pump Mayer GPD 50-20 F

The Mayer GPD 50-20 F is the most powerful pump in the F-series, designed for large-scale heating and water systems. Equipped with a DN50 flanged connection, it is ideal for high-capacity mains, boiler rooms, industrial installations, heat-exchange systems, and facilities with extensive heating areas.

The pump delivers high head pressure and increased flow, withstands elevated temperatures, and operates reliably even under continuous load.
