    Equipment for Mining and Extraction

    Mining exposes equipment to extreme abrasion, slurry with hard particles and continuous operation in galleries or deep shafts, where IP68 protection and wear-resistant materials are essential. We quote slurry pumps, heavy-duty submersible pumps for drainage, knife gate valves, hydraulic systems for machinery and dust filters. Send the solids concentration, the particle size and their hardness for correct sizing.

    Frequently asked questions

    What makes a slurry pump different from a standard centrifugal pump for abrasive sludge?

    A slurry pump has its impeller and casing made of high-hardness alloys (for example white chromium cast iron, with a hardness above 600 HB) or a natural rubber lining, specifically to resist the erosion caused by the solid particles in suspension. The impeller geometry is usually more open (fewer vanes, wider channels) than on a standard centrifugal pump, to tolerate large particles without blocking. Correct selection takes into account the solids concentration (percent by weight), the maximum particle size and their hardness - send us these data for sizing the impeller and the material.

    Which valve do I use on a line with a high solids content or ore concentrate?

    Knife gate valves are the standard choice for these lines, because the blade can cut through solids build-up when closing, unlike a ball or butterfly valve, which would quickly jam. For extremely abrasive media we recommend versions with a lined body (rubber or polyurethane) and a hard stainless steel blade, which last longer than plain cast iron. Also check whether you need bidirectional sealing (pressure from both directions) or only unidirectional, because this choice affects the price and the complexity of the construction.

    What criteria matter for a submersible pump for mine drainage?

    Besides the impeller's abrasion resistance, a drainage pump for galleries or shafts must cope with intermittent operation, sometimes at great depths, with water that may contain sand, fine ore particles and, occasionally, traces of processing chemicals. The motor must have IP68 protection (continuous immersion) and cooling suited to the submerged environment, plus moisture sensors in the casing for early detection of leaks. For galleries with a risk of gas accumulation (methane), check whether the electrical equipment installed in the area requires ATEX certification.

    What hydraulics are needed for heavy mining machinery (excavators, loaders)?

    Hydraulic systems for mining machinery work at high pressures (often above 300-350 bar) and must resist contamination with dust and fine particles, the main reason for premature failure of hydraulic pumps and directional valves in this environment. Filtering the hydraulic oil to an adequate cleanliness class (according to ISO 4406) is essential - contaminated oil rapidly wears the precision components of proportional valves. We supply replacement cylinders, pumps and valves compatible with most heavy machinery, plus filtration consumables for preventive maintenance.

    How long does delivery take for a critical part for a slurry pump or a stopped mining machine?

    For impellers, casings and wear seals from the usual range, the lead time is 24–72 h when the item is available locally or at the supplier. An unplanned shutdown of an ore processing line costs a lot per hour, so send the part code in good time. For equipment built to order (specially sized slurry pumps, hydraulic cylinders with non-standard dimensions), usually 1–4 weeks; it may take longer depending on the brand and the specifications. If you have a production emergency, call us or send the equipment code or photos of the nameplate - we check availability and give you the lead time.
