Project Description

The problem

In the industrial sector it is often necessary to empty lagoons and settling ponds. But very frequently, in this context, the waters and sludge to be treated are dangerous and can cause a great deal of damage to any equipment if it is not properly protected. This damage presents itself as corrosion.

Recently, for example, a remote controlled dredge has been chosen to work in the water intake basins of the largest Egyptian power station (Burullus power plant), a “monster” 4800MW combined cycle generation plant.

The solution

For this particular operation, all components in contact with the water, or exposed to the atmosphere, have been protected for with C5M corrosion class coating (the highest corrosion class in the ISO 12944 normative) and some critical components were made in Super Duplex steel for an extreme reliability even in this type of applications.

Thanks to these measures, the equipment supplied proved to be perfectly adapted to work in a very corrosive environment, while maintaining the expected production capacity.

It should be remembered that the DRP series can pump fluids up to a concentration of 70% solids by weight, with a flow rate of up to 1000 m3/h and a delivery up to 1000 m distance from the point of dredging.

All our dredges can be integrated with many accessories, among which we mention the GPS, the security video camera and the system to follow and record the history of the operations of the dredging pump.

It should also be mentioned that Dragflow has developed a new series of exsustenitic stainless steel pumps (CK3MCuN), resistant up to ph 1.5: a very important complement to work without worries in extreme environments!
