Metal Lined Sand Gravel Pump for Lake Dredging River Sand Removing
Introduction:
Type SG are single casing heavy duty metal gravel pumps designed for higher head duties such as cyclone feed, long distance pipelines and high static discharge heads. SME SG Series pumps are designed to handle very large particles for gravel and dredging operations. Capable of handling large particles at consistently high efficiencies results in low cost of ownership. The large volume internal profile of the casing reduces associated velocities further increasing component life.
