Macnaught DDP38AN 40mm High Flow Air Operated Diaphragm Pump (Max 600LPM)

The Macnaught DDP38AN is a powerful air-operated double diaphragm pump engineered for high-volume industrial fluid transfer. Designed as part of the Max Flow series, it delivers up to 600 LPM (158 GPM) while maintaining low air consumption. Ideal for handling slurries, high-viscosity, and abrasive fluids, it features a robust aluminium body with Nitrile Buna-N (NBR) diaphragms for excellent durability and chemical compatibility.

The DDP38AN’s center port and threaded flange manifold design offer flexible connection options, making installation easy in demanding industrial environments.
