Specifications
Specially designed impeller allow the handling of extraordinarily
large particles. Long wear life and easy to maintenance.
Dredge pumps are available with suction diameters from 250 to 1, 400mm; though customised pumps have been made beyond these parameters.
The material to be dredged is almost always abrasive, sometimes to extremes. The threat of wear does not so much lie in the direct cost of an item to be replaced, but in the resulting downtime due to installation, in the case of both larger and smaller vessels.
Important characteristics:
* Long working life in abrasive conditions
* Efficiency up to 92% (as measured in practice) resulting in lower fuel consumption at unchanged
production
* Reduced and more even wear, resulting in longer lifetime of wear parts
* Better performance as a result of the low net positive
* Suction head required (NPSHR)
* Highly versatile application due to steep flow head ratio curve
* Limited influence of wear on pump performance
