Shipshape order for large dredge pump

By Steve Ormondroyd, workshop manager
​
This large pump built by the Dutch company Nijhuis Pompen comes from a ship and was sent to us for repair. In operation, it uses its maximum 635 kW power and 1500 M3/H capacity to dredge the sea bed.

It will be dismantled and meticulously inspected to identify any reclamation work required to return its performance to the level of when it was manufactured. 

We will be looking out for:

• Mechanical wear on the impeller wear rings and the pump case rings
• Water erosion and cavitation on the pump casing
• Any damage present on the impeller.

As is routine with pump repairs of this nature, we will replace any seals, gaskets, O rings & bearings. We will also dynamically balance the whole rotating assembly to G6.3.
