Along this long pipeline there are some booster stations and speed control valves. When those are under maintenance they need to stop the pumping to the shore and material coming from the plant is diverted and discharged into a tailing pond.
It is crucial for the project to maintain the maximum capacity of this pond in case they need to deal with emergencies.
For this reason, the customers needed a machine capable to dredge the iron tailings and to return them to the circuit going to the coast.
The tailings have a high content of Iron with specific gravity up to 4,9 kg/dm3. Only a super duty dredging pump with an oversize motor could do the job.
