Macnaught DDP25SW 25mm High Flow Air Operated Double Diaphragm Pump (Max 180LPM)

The Macnaught DDP25SW is a high-performance air-operated diaphragm pump engineered for industries where hygiene, precision, and durability are essential. With a maximum flow rate of 180 LPM (48 GPM), the DDP25SW is ideal for food & beverage, pharmaceutical, cosmetic, and chemical applications requiring high flow rates and low air consumption.

Constructed with stainless steel wetted parts and PTFE/EPDM diaphragms, the pump ensures superior sealability, leak prevention, and resistance to a wide range of fluids. The clamped ferrule connections allow for quick disassembly, facilitating effortless cleaning and maintenance while maintaining sanitary standards.
