Single Casing High Chromium Wear Resustant Gravel Pumps for Sand and Aggregates
Introduction:
SG Series heavy duty dredge and gravel pumps are designed for continuous handling of the most difficult higher abrasive slurry, containing solids too large to be pumped by a standard slurry pump.
The Heavy Duty Gravel Pump is designed for higher head duties such as cyclone feed, long distance pipelines and high static discharge heads.
The Heavy Duty Dredge Pump, is specifically designed for low head duties such as hopper dredging and barge loading.
