The DDP50 offers an economical and reliable pump for transfer of light to medium viscosity fluids. High flow rates can be achieved easily especially where low back-pressure applications exist. The ability to dry-run allows easy priming while operating without any damage to the pump. The Cast Aluminium body allows this pump to be used with a range of compatible chemicals as well as the new or used oils and engine coolants (RTU), diesel or oily water applications. Fully repairable and spare parts are readily available. Not suitable for flammable liquids.
