    The screw horizontal slurry pump is suitable for conveying underflow materials under raw material mills, ball mills and thickeners in various industries, and effectively solves the phenomenon of blocked pipes and overflows in the operation of ordinary centrifugal slurry pumps.

    The screw submersible slurry pump adopts the integrated structure of the anti-sewage motor and the downward suction of the screw slurry pump. The whole pump can be submerged in the liquid for a long time to work. The submersible slurry pump adopts the impeller with large channel and anti-clogging function, which greatly expands its application range. Using advanced electronic control technology, the pump has automatic protection functions such as overload, phase loss, overheating and leakage. It is suitable for conveying mixed slurries with high concentration and high viscosity that are easy to precipitate and contain insoluble solids such as sediment, sludge, coal gangue, cinder, and fibers.

    The spiral vertical slurry pump is suitable for the occasion of extracting the mud slurry in a fixed position. Due to the use of a spiral centrifugal impeller, it can transport insoluble solid phases containing large particles of sediment, sludge, coal stone, cinder, fibers, etc. It is easy to precipitate mixed slurry with high concentration and high viscosity.
