Macnaught DDP50 50mm Air Operated Diaphragm Pump (Max 598LPM)

The Macnaught DDP50 offers an economical and reliable pump for transferring light to medium viscosity fluids. Designed for high-volume performance, it easily achieves high flow rates, especially in low back-pressure applications. The ability to dry-run makes priming easy without risking damage to the pump.

Its robust cast aluminium body ensures compatibility with a wide range of chemicals, making it suitable for oils (new & used), engine coolants (RTU), diesel, and oily water applications. Fully repairable, with spare parts readily available. (Not suitable for flammable liquids.)
