Applications & Use Cases

Industrial Slurries

WEDA L application

WEDA L50N slurry pumps' high abrasion resistance makes them an excellent choice for industrial slurries.


WEDA L application

Slurry pumps for dredging are used to remove contaminants from water, move sediment, create waterways, and mine for metals. The WEDA L50N pump is designed for the toughest applications thanks to its high durability and abrasion resistance.
