How to Select a Dredge Pump or Slurry Pump
Dredge pump or slurry pump selection could be a challenging process which could be simplified with the understanding of the primary factors behind smooth pump operation. Apart from delivering a more efficient performance, the right dredge pump requires lesser maintenance, reduced power and has a relatively longer life.
Slurry pump and dredge pump terms may be used interchangeably.
Definition of Dredge Pump and Slurry Pump
Slurry pumps are the mechanical devices utilized for pressure-driven transport of a fluid mixture (aka slurry). 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.
Dredge pumps are a special category of heavy-duty slurry pumps that are utilized in the process of dredging. 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). 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. Hence, various industries that utilize dredge pumps are the construction industry, mining industry, the coal industry, and oil & gas industry.
