Bochum-based Habermann Aurum Pumpen GmbH was based in 1927, as mining in Germany peaked and the Ruhr space, the place the corporate has been based mostly since these early years, grew to become a significant industrial hub and one of many world’s main mining areas. The corporate will likely be exhibiting at MINExpo this yr from September 24-26 in Las Vegas in West Corridor, Sales space 10603.
Through the years, it says it has gathered beneficial information from the mining sector and tunneling building and developed strong pumping options, designed to endure even essentially the most abrasive functions and guarantee dependable efficiency within the hardest mining environments.
Steady operation below harsh and unexpected situations accelerates the damage of mechanical elements in pumps. Slurry pumps have sliding put on not solely attributable to very wonderful solids but in addition attributable to excessive proportion of coarse particles. They have to deal with abrasive slurries with coarse-grained solids, which trigger vital put on on pump elements. Moreover, the corrosive nature of sure ores and chemical compounds utilized in processing can additional deteriorate pump supplies.
Habermann Aurum Pumpen designs heavy-duty KBKT-series centrifugal pumps from extremely wear-resistant excessive stainless steel to resist these harsh situations. These pumps deal with a variety of strong sizes, from the best grains to coarse particles as much as 250 mm, making certain dependable and environment friendly efficiency. “The KBKT-series options robust wall thicknesses for impellers, housings and put on plates. A vital issue for dependable solids transport is sustaining a minimal movement velocity to forestall sedimentation, which is decided by the sinking fee of the solids. This fee is determined by the mineral weight, grain dimension, grain form and transport focus. For coarse grains, it’s important to make sure that the utmost grain dimension doesn’t exceed half the pipe diameter.”
In chemical processing inside mining, pumps are important for dealing with numerous reagents and chemical slurries used within the extraction and processing of minerals. Right here, pumps should be immune to chemical corrosion and able to dealing with a variety of fluid viscosities and densities. The HPK-series pumps, with their elastic linings, it says are significantly fitted to such environments, offering glorious chemical resistance and sturdiness.
Dependable pumping tools may also be a decisive success think about many underground infrastructure tasks involving water and vitality provide, in addition to water elimination and microtunnelling. The highly effective and extremely wear-resistant pumps from the KB- and NPW-series characteristic a compact design, tailored for supply or feed operations below the confined set up situations of microtunnelling and pipe jacking. Low building heights, extremely wear-resistant supplies, and shaft seals with both an expeller or our self-developed mechanical seal, HGD, guarantee protected use in AVN jacking methods.
This sequence has tunnel variations for microtunnelling, the place area is proscribed, and shaft variations as feed or booster pumps from the shaft to the separation plant. The shaft variations are extra generally used for bigger pipe jacking dimensions, with variably adjustable discharge nozzle settings inside technical limits. A high-performance separation plant is a essential element for processing bentonite slurry enriched with sand and solids, making certain excessive pipe jacking efficiency on building websites for visitors and provide tunnels, and in specialised civil engineering tasks. The wonderful and coarse-grained soil elements within the pumping circuit demand distinctive put on resistance from the supplies used.
