Primary selection requirements for dredge pumpsĪpart from economic considerations, two primary selection considerations for dredge pump operation are no settlement of sediments in the pump and minimum amount of wear and tear in the pump due to the flow operation. Hence, various industries that utilize dredge pumps are the construction industry, mining industry, the coal industry, and oil & gas industry.įigure 1: A specialized dredge pump attachment for excavators, in the dredging process Dredging takes place in shallow water areas of lakes, rivers or ocean for the purpose of land reclamation, desilting, flood prevention, creation of new ports or expansion of existing ports. Dredging is referred to as the process of transport of underwater sediments (usually sand, gravel or rocks) from one region to another (a piece of typical dredging equipment is shown in Figure 1). The fluid mixture by and large consists of water as a liquid with solids being minerals, sand, gravel, human waste, drilling mud or most of the crushed materials.ĭredge pumps are a special category of heavy-duty slurry pumps that are utilized in the process of dredging. Slurry pumps are the mechanical devices utilized for pressure-driven transport of a fluid mixture (aka slurry). Compare the price to comparable Briggs and Stratton intek or Honda pumps.Definition of Dredge Pump and Slurry Pump Pump is made in the USA and engine in China. This is a real workhorse pump designed to power a 3 or 4 inch gold dredge or a large combination dredge hibanker unit.
