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 new or used oils, engine coolants (RTU), diesel or oily water applications.
It is fully repairable and spare parts are readily available. Not suitable for flammable liquids.
Features
Flow Rate: Up to 598 litres per minute, measured with water at the pump outlet.
Band Clamps: Fitted with band clamps on the inlet and outlet manifolds for easy dismantling to repair or clear blockages.
Cast Aluminium Body: Cast aluminium body for a wide range of chemical compatibility and broader applications.
Speed Control: Air-operated pumps can be speed controlled for more control over output.
Fast Transfer: Fast fluid transfer for low to medium viscosity fluids, an inexpensive way to move large volumes.
Self-Priming: Easy self-priming with no damage to the pump while running with little or no fluid flow for short periods.
