Slurry pump for mining industry

Mining companies seeking an efficient way to handle abrasive slurry can now use KSB/GIW Industries' ZW Vertical Slurry Pump Series which is claimed to provide an economical solution for vertical sump requirements.

The KSB/GIW Industries ZW Vertical Slurry Pump can be used in applications such as dewatering, floor cleanup, sump overflow and groundwater seepage conditions. Although the pump can easily withstand the rigours of many mining applications, its basic design makes it easy to maintain. Both complete pump assemblies and spares are readily available.

The pump was tested in Australia, where rugged gold-mining conditions require a highly functional, durable and low-maintenance slurry pump. The pump's high chrome material configuration allows for maximum wear resistance necessary in mining equipment.

"We had a lot of influence from Australia, where this type of pump is popular," explains Richard Inglett, Market Manager at GIW Industries. "Their input was key. They really stressed a double-suction design and market price."

The ZW Vertical Slurry Pump features a double-suction vertical design ideal for handling aggressive, abrasive slurry applications. Instead of stopping and starting as water levels fluctuate, the pump's top- and bottom-suction design allows it to run continuously in a ‘snore condition’ to provide more consistent pump action and to reduce pump stress. Additionally, its semi-open impeller design permits large solids to pass freely.

The design was developed over a two-year period, and special care was taken to ensure that each part of the pump would meet the stringent requirements of potential users. Specific attention was paid to data analysis and testing to determine proper motor-mount specifications in order to maximise the pump's efficiency and avoid surprises and delays for end users.
