Description
Air Operated Diaphragm Pump - 1 1/2"
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.)
FEATURES
- Up to 265 L/min flow rate, measured at the pump outlet with water
- Fitted with band clamps on inlet and outlet manifolds for easy dismantling, repairs, or clearing blockages
- Cast aluminium body for wide chemical compatibility across multiple applications
- Air-operated design allows speed control for adjustable pump output
- Cost-effective solution for fast transfer of low to medium viscosity fluids
- Easy self-priming and dry-run safe for short periods without damage
