Production Decsription

Pansto WN sreies Sand Dredging Pumps are robust equipment designed for heavy-duty sand dredging applications, also known as sand extraction, sand mining, and sand excavation pumps. These units serve as reliable dredge pumps for sand on dredgers or can be seamlessly integrated with submersible sand slurry pumps to act as booster horizontal sand pumps across extensive distances. They boast outstanding wear resistance, anti-cavitation, and anti-clogging abilities, ideal for deepening waterways, preventing siltation, or excavating sand from the bottoms of rivers, lakes, estuaries, and other aquatic areas.

FAQ

What does a dredge pump do?

A dredge pump is a rugged centrifugal pump that efficiently moves sediment, sand, gravel, debris and various other solids from the ground to a designated discharge point through a pipe or hose. It excels at handling abrasive granular materials and solids of various sizes and weights and effectively suspends them.

What is the difference between a dredge pump and a slurry pump?

Dredge pumps are a special category of heavy duty slurry pumps that are utilized in the process of dredging.

What is the purpose of dredge?

Dredging is the removal of sediments and debris from the bottom of lakes, rivers, harbors, and other water bodies. It is a routine necessity in waterways around the world because sedimentation—the natural process of sand and silt washing downstream—gradually fills channels and harbors.
