Macnaught DDP38 40mm Air Operated Diaphragm Pump (Max 265LPM)

The Macnaught DDP38 offers an economical and reliable pump for transferring light to medium viscosity fluids. High flow rates can be achieved easily, particularly in low back-pressure applications. The pump is capable of safe dry-running for simple self-priming without damage.

Featuring a robust cast aluminium body, the DDP38 is compatible 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.)
