MechChem Africa visits the new expanded premises of Integrated Pump Rental (IPR) and Integrated Pumps Technology (IPT) and talks to IPR’s managing director, Lee Vine.

With 13 years previous experience in the pumping industry – as an applications engineer on the dewatering side; head of a mining and minerals pumping division; and as a rental division manager – Lee Vine has been with IPR since its inception in 2015.

Slurry Sucker Integrated Pump Rental“With all my experience on mines I saw a need for a solution for silted-up lined ponds. This sparked an idea for my own dredge, which we started to design as soon I joined IPR,” Vine reveals.

The end result is IPR’s proprietary Slurry Sucker, which has achieved instant success as a rental solution. “Our Slurry Sucker meets the need to clean lined process ponds, removing the accumulated slurry deposits from the pond floor,” Vine says.

Notably, the Slurry Sucker system does not require submersible pumps with cutter heads to agitate the settled sludge, which tend to damage the liner. “We pump water through the dredge head to disturb the sludge, and we immediately pump the slurry up and out of the pond. This means that we can clean a pond while it is online, since the disturbance is contained in the region immediately surrounding the dredge head and all of the displaced slurry is evacuated immediately,” he explains.

Describing the components of the system, Vine says that two 18 kW dewatering pumps located in front and at the back of a floating pontoon are used to draw water from the top surface of the pond. This water is pumped through front and back jetting bars to agitate the slurry on the pond floor.

“A submersible slurry pump suspended underneath the pontoon is then used to evacuate the disturbed area, pumping the slurry through floating hoses out of the pond,” Vine tells MechChem Africa.

“To move the Slurry Sucker across the pond, we use a transferring rope system with winches, which pull the system from one side to the other. After each pass the height of the suspended slurry pump is automatically dropped a further 100 to 200 mm, and once the ‘cut’ is completed, the tensioning winches are moved across a further two metres and a new cut line is started,” he says, adding, “this design suits ponds of 5.0 to 6.0 m deep that are, typically, 150 by 150 m in area.”

Vine says that, at many of the process circuits on our mines, due to lack of maintenance and/or incidents such as thickener breakdown, “I have seen the accumulated silt from process water ponds being fed back into the processing stream, with costly consequences. Our Slurry Sucker rental solution is ideal for preventing that from happening, safely and reliably, without having to shut down the processing plant or having to invest in new equipment,” he points out.

“And for bigger ponds, or where the pond is caked with dry thick slurries with too little surface water, we can clean the pond using our hydro-mining solution called Slurry Blaster. This involves taking clean water from another pond or source and then blasting the slurry material towards the pump to create enough suspension to pump off the slurry. But this has to be done offline,” says Vine.

“Both of these rental options are 100% turnkey solutions. We do not simply hire out equipment and deliver to site. Following a technical onsite consultation, we supply all of the equipment and accessories needed to clean the pond in question, then we install it and oversee the entire cleaning process, which can take months. We then leave with our equipment after the job is done,” he assures.

Diesel-powered pit dewatering from Sykes

IPR took responsibility for the Sykes brand in 2016 with immediate rental success. “We have only been the exclusive Sykes agents for a little over a year and we have already filled our rental fleet with Sykes solutions. When people rent our equipment and see how effective and reliable it is, they find it much easier to justify a purchase,” he suggests.

Vine cites a recent success in the coal industry involving Sykes CP150s ...
