Centrifugal and AODD mining pumps support dewatering and corrosive fluid transfer

Finish Thompson supplies a range of pumps designed for mining industry applications, including corrosive chemical transfer, dewatering, and slurry handling operations.

According to Finish Thompson, mining operations can apply the company’s DB Series and SP Series centrifugal magnetic-drive pumps, along with FTI Air air-operated double-diaphragm (AODD) pumps, depending on operating requirements.

The DB Series and SP Series sealless magnetic-drive centrifugal pumps are intended for above-ground mining applications involving chemical processing and corrosive fluid handling. Applications include mineral extraction, hydrometallurgical recycling, leaching, reagent circulation, separation, refinement, and other acid or caustic processes.

The company said the DB Series delivers operating efficiency up to 70% and handles working pressures up to 90 psi. The pumps are designed for continuous chemical transfer from bulk storage tanks to process or day tanks where leak-free operation is required.

The SP Series is designed for corrosive chemical transfer applications requiring self-priming and top-draw capability. The pumps can be used for loading and unloading tanker trucks and rail cars, as well as transferring fluids from the top of bulk tanks to reduce potential leak points.

According to Finish Thompson, both pump series use sealless magnetic-drive technology and corrosion-resistant materials to eliminate mechanical seals, reduce maintenance requirements, and support safe handling of aggressive mining chemicals.

FTI Air AODD pumps are designed for below-ground and water-based mining applications, including dewatering, sump pumping, slurry transport, and equipment maintenance. The pumps can handle fluids containing suspended solids, sludge, tailings, and abrasive slurries.

Finish Thompson said the pumps are suitable for operating conditions involving fluctuating water levels, changing discharge pressures, variable suction lift, and dry-run conditions. The air-operated pumps are self-priming, can run dry, and can deadhead without damage.

The company added that the air-driven pump design, along with metallic and non-metallic material options, supports operation in hazardous or remote mining locations where electricity at the pump is limited or unavailable.
