The range now comprises three families; the expanded WEDA D for dewatering, WEDA S - also expanded - for sludge, and the entirely new WEDA L slurry family. WEDA D pumps handle either clean or dirty water, even with small solids. The WEDA S range supports dewatering of liquid sludge containing larger solids. The WEDA L products are the toughest and have the largest apertures to facilitate handling of slurry with the most challenging solids.
The WEDA D family expansion is marked by the D80, a new model for dewatering. S30, and S60, as the new models for the WEDA S sludge family, can handle thick, soft, wet mud or other similarly viscous mixtures of liquids and solids, especially the product of an industrial or refining process. The completely new WEDA L family handles semi-liquid slurry mixtures, typically of fine particles of manure, cement or coal, and water.
Overall, the WEDA D pumps, which use top-discharge, can handle water of specific gravity to 1100kg/m3, and, depending on the model, solids of 4 - 12mm diameter. The bottom side discharging WEDA S pumps' capabilities extend to water with specific gravity to 1400kg/m3, and solids of 25 - 50mm, depending on the model. The WEDA L pumps, which also use bottom side discharge, handle water of specific gravity up to 1700kg/m3, and, depending on the model, solids of 20 - 60mm diameter.
The pumps' specifications equip them for an extensive range of dewatering applications; providing performance, reliability and ease of use and maintenance essential to users across multiple industries. All models feature a built-in starter and motor protection system along with optional automatic level control. Adjustable wear-resistant rubber diffusors and hardened high-chrome impellers ensure durability in tough environments.
"The WEDA pumps can handle flow rates of up to 16,500l/min, with power ratings up to 54kW," explained Hrishi Kulkarni, product manager, Atlas Copco Power and Flow division. "Accordingly, they make ideal dewatering solutions across many, diverse applications within the construction, industrial, emergency and maintenance sectors."
