FITT Resources supplies operators in the Australian dewatering industry with Dragflow DRP remote control dredges that are extremely versatile and can be used in a wide range of applications, and which provide safe operation and increased efficiencies.
The Dragflow DRP remote control dredges offers lower operational and maintenance costs when compared to traditional Sludge & Slurry removal methods, while less manpower is required, leading to increased productivity and more cost-effective operation.
The Dragflow DRP remote control dredges have a working depth of up to 50m below the surface, and can reach a discharge distance of up to 1km. It is ideal for high solid content (up to 70% concentration by weight), with power from 110kW and a pumping capacity of up to 1000m³/h. The Dragflow DRP remote control dredges can handle solids up to 90mm, significantly reducing the chances of clogging.
The Dragflow DRP remote control dredges is ideal for a variety of applications and across a number of different industries:
- chemical and industrial plant remediation
- mining remediation
- harbour and marina dredging
- channel, pond, lagoon, dam and canal cleaning
- sand extraction
Owing to its portability, the Dragflow DRP remote control dredges can be used in a variety of locations, even those where access is not straightforward. Using a modular design, the dredge can be transported in a container and, because it doesn’t require equipment to be dismounted and remounted when moving between locations, it is very simple to transport and assemble.
In applications where wastewater presents a hazard to workers, an unmanned dredge significantly reduces risk. The Dragflow DRP remote control dredges can be controlled by a single operator onshore from as far away as 500m, and an explosimeter can be fitted if necessary.
The dredge features a winch, ladder or telescopic beam for moving the pump in and out of the product.
The hand-held remote control operating system offers a number of features that increase precision in operations.
For instance, the dredge can be manoeuvred into the position required by an onshore operator, with the aid of GPS if required. Operators also have an instant view of the working depth of the pump, which can be calculated precisely, as well as the pump load, and its movements both horizontally and vertically can be controlled remotely with accuracy. The remote control operation enables the production of solids to be maximised at the set flow rate, while an advanced control panel also registers your dredge pump operations history.
The Dragflow DRP dredge features a double blade agitator with pump suction, and this makes direct contact with the material being dredged. In this way, it is able to move slurries with a solid content up to 70% and so less water needs to be moved. This reduces energy use as smaller diesel engines and discharge pipe diameters can be used, further reducing operating costs.
Wear parts are manufactured in high chrome and designed to have high abrasion resistance. Combined with low rotation speeds, this means longer intervals between maintenance and component replacement, and reduced downtime.
In addition, during operations low turbidity is created and so contaminated sediments can be removed without harming the surrounding environment.
