Project Description

SDG02

Sproull® SDG Mine Dewatering Multistage Pump is self-balancing multi-stage anti-wear pumps, which adopt the hydraulic model recommended by the state for high-efficiency energy-saving product. It can be used for transporting clear water without solid particles (abrasives), suspended matter or other liquids with physical and chemical properties similar to clear water. It can also be used to transport hot water,oil, corrosive or abrasive media by changing the material of the pump (or the material of the flow passage part of the pump), sealing form and increasing the cooling system.
The utility model has the advantages of high efficiency, wide performance range, safe and stable operation, low noise, long service life, convenient installation and maintenance, etc.

Working Condition:

Capacity: 3.7-1350 m³/h
Head: 70-1800 m
Speed:2950,1480 r/min
Power:5.5-4500kw

Design features:

• High pressure, High head, Long distance transporting
• Strong wear resistance materials
• High efficiency, wide performance range
• Operation safely and stably, low noise
• Convenient installation and easy maintenance
• Long service life, reliable performance

Sproull® SDG Mine Dewatering Multistage Pump apply to drainage works in steel works and mine, it is intended to deliver mine drainage and other sewage whose solid content is not exceed 1.5% and particle is not exceed 1.3 mm.
