PUMPS
The new Slurrysucker Mark II design incorporates the use of a vortex type impeller in the slurry pump, so that the unit can handle solids up to 76 mm through the impeller
dredge head allows solids up to 76 mm in size to be pulled in with the sediment and passed through the system without creating blockages.
By comparison, the original SlurrySucker Mark I design has sixteen 32 mm holes through which the silt enters the pump. The new Mark II unit still uses water to agitate the solids, and does not have cutters that could damage the pond liner.
“ We have a dewatering pump located on the dam surface which feeds the dredge head through 16 nozzles with 7 bar pressure, enabling the water to‘ cut up’ the solids so that it can be sucked away,” he says.
The SlurrySucker is designed for dredging mine ponds and process water ponds with dimensions of up to 150 m by 150 m and with depths of about 6 m. He notes, however, that a new model is currently in design that will allow the dredging of larger dams.
Integrated Pump Rental’ s innovative dredge units play a valuable role in helping customers in terms of both operational performance and environmental protection.“ The build-up of sediments in process water ponds and other water storage areas, which threatens their water holding capacity, can severely disrupt processes, and this is irrespective of whether it is on a mine or a wastewater plant,” says Vine.“ This can also potentially create an environmental hazard, which has seriously implications for an operation’ s legal compliance and licence to operate.”
The SlurrySucker is a quick and simple solution to this challenge, and is manufactured using locally produced components. To develop optimal designs, the company made use of computational fluid dynamics( CFD) for validation, assuring customers that the performance of the SlurrySucker and its engineering integrity are maximised.

Technological Innovations That Revolve Around You
( JSL) plant in Bhilwara, India, an area rich in magnetite deposits but low in quality ore. Although JSL’ s special beneficiation process had enabled the company to produce good-quality ore pellets, this led to excessive wear on the plant’ s slurry pumps.
“ Initially, JSL used our hard metal HM pumps that were part of a larger equipment delivery. Although performance was fine after installation, the new pumps wore out in only two months due to an unusually high percentage of silica in the slurry, causing extreme wear to the pump casings. Thorough investigation of the problem opened a variety of options on how to help JSL plant extend the wear life of its slurry pumps. One possibility was to replace the metal casings of the pumps with rubber-lined HR casings to
