The comprehensive coverage has been achieved by completing the ranges for drainage and sludge applications and adding a completely new range for slurry applications. The company says that selection from the entire expanded range is simplified as all models are classified by application and type of fluid that they handle.
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 enable handling of slurry with the most challenging solids.
The WEDA D family expansion is marked by the new D80 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 new WEDA L family handles semi-liquid slurry mixtures, typically of fine particles of manure, cement or coal, and water.
Atlas Copco says that a lot of focus has been put on making the pumps lighter, enhancing electrical safety, improving the seal design and easing installation. All pumps in the D and S range are available with WEDA+ features, which include phase-failure protection, rotation control, thermal switches and a 20 m cable with phase-shifter plug for all 3 phase pumps. The WEDA+ features are also available as an option on the L range.
