The WEDA S30N sludge pump features a max head of up to 61ft, max flow of 230USgpm, and can withstand solids of up to 2in.


The WEDA sludge pumps can handle thick, soft, wet mud or other similarly viscous mixtures of liquids and solids, especially the product of an industrial or refining process. These pumps are particularly suitable for mining applications, trench and pond-cleaning, tank cleanout and for water containing mud, sludge or light slurry.

Applications & Use Cases

Our WEDA S30N Submersible pump is commonly used for pumping sewage. Used for temporary bypassing of either gravity sewer lines or pump stations, the WEDA S30N pumps are up to the challenge.

Alum Sewage


A byproduct of water purification, alum sludge accumulates at water and wastewater plants. WEDA S30N pumps excel at pumping this, allowing it to be removed from the site.

Sludge pumps for dredging are used to remove contaminants from water's surface, move sediment, create waterways, and mine for metals. The WEDA S30N pump is designed for submersible applications thanks to its high durability and abrasion resistance.
