Pumps for Mining Applications

ABELs pumps for mining applications run slowly when conveying abrasive tailings or viscous backfill paste. Especially piston diaphragm pumps type HM are used in this field. ABEL SH is the perfect choice for safely conveying viscous, paste-like mine slurry over a longer period of time. These meet the requirements of challenging tasks in open pit and underground mines throughout the world.

No matter whether it’s a tailing pump, slurry or dewatering pump – ABEL has the solution. Piston diaphragm pumps have a respectable service life due to the diaphragm, which separates drive and medium. Furthermore, the equipment has been improved over the years. For mining applications with particularly aggressive media, ABEL provides wetted parts made of stainless steel or duplex stainless steel – such as acidic ore sludge.

ABEL recommends HMT and HMQ as mine dewatering pump. Their high pumping capacity and sturdy, high pressure design allows drainage of mine water in only one stage to the surface.

Backfilling requires extremely robust high-performance pumps – most of the time with high pumping capacity at high pressures. ABEL HMQ and SH are used for this purpose even if conditions are extreme. They provide constant flow rates and can transfer pasty media, even when mixed up with cement.

Tailings transfer means, pumping tailings to a pond – this can be characterized by long distances with high pressure, high flow rates or high solids concentration. We have many tailing pumps in the field that reliably do this job day after day. Since ABEL can handle tailings with a solids content of up to 75%, additional water for sealing is not necessary. Just another reason in favor of ABEL.

Advantages over Centrifugal Pumps

There are many advantages in favor of a piston diaphragm pump. It is not without reason that oscillating pumps have been preferred for some years now, especially in modern, efficiently operated mines.

  • pumping higher solids concentration
  • greater overall efficiency
  • smooth operation and low speed causes less wear
  • higher availability: long life cycle and process reliability
  • constant flow regardless of pressure and viscosity
  • no water for sealing

ABEL Benefits

Individual Pump Configuration

Our pumps are tailored to the customers needs. We offer different accessories and material combinations for different applications and fluids.


Our pumps can pump at high pressures without a problem and are ideal for highly abrasive media. Their robust construction makes them perfect for 24/7 operation.

Safe Pump Operation

ABEL pumps can inherently run dry and in general they are slow-stroking during standard operation.
