Many mining processes require dewatering. Rotary lobe pumps are well suited for feeding dewatering devices because of their ability to pump a measured, near pulseless flow at any pressure within the pump’s PSI range. Additionally, mining applications are often abrasive. Pump wear rate is greatly effected by pump speed. Typically, rotary lobe pumps run at 200-300 rpm in abrasive applications whereas centrifugal pumps are typically run at 1750 rpm. This results in much faster wear for centrifugal pumps. Rotary lobe pumps deal well with soft, compressible solids and fine abrasives. We recommend that hard solids greater than 1/8″ (3 mm) be removed with an in-line grinder, filter, or knock-out tank.
We have a broad variety of materials available including grey iron, stainless or duplex steel wet ends and Viton, EPDM, NBR or steel lobes to custom engineer a pump best suited to your application. Options include LobePro S-Series (sludge/slurry) pumps and C-Series (chemical/and corrosive resistant) pumps. Each model can have benefits to your application.
Typical mining applications include:
- Filtrate/Precipitate Pumps
- Belt Press and Centrifuge Feed Pump
- Primary Clarifier Scum Pump
- Secondary Clarifier Scum Pump
- Flocculents Solutions Pumps
- Paste Thickener Feed Pump
- General Service Water Pump
