Tough Conditions Call for Tough Pumps
Mining operations involve abrasive slurries, heavy solids, and unpredictable flow. The QBY diaphragm pump handles these conditions because it has no close-clearance parts. Solids up to 10 mm pass through without damage.
Where Miners Use It
•
Dewatering mine shafts and tunnels
•
Pumping thickener underflow
•
Transferring flotation concentrates
•
Handling mill scale slurry
•
Moving tailings to disposal areas
Why It Lasts
The slow stroking action reduces wear. Cast iron or stainless steel bodies resist abrasion. Replaceable diaphragms and ball valves are inexpensive and easy to change.
Field Tip
Install a pulsation dampener on the discharge to smooth flow. This reduces stress on downstream piping.
Applications Summary:
mine dewatering, slurry transfer, thickener underflow, flotation concentrate, tailings handling, mill scale, mining
