Mining submersible pumps are primarily used for drainage in central pump rooms of coal mines, emergency drainage after waterlogging disasters in coal mines, or for re-mining drainage. Centrifugal pumps are commonly used. The commonly used types of submersible mining pumps include D-type, DA-type, and TSW-type multi-stage centrifugal pumps; while for local drainage at the bottom of wells and mining areas, B-type, BA-type, and BZ-type single-stage centrifugal pumps are often employed. Multi-stage centrifugal pumps are also available for higher lift applications.
