Specifications

About the WEDA L50N

The Atlas Copco WEDA L50N is a 7.4 HP submersible pump for abrasive slurry in dredging and settling-pond work. Its high-chrome agitator helps keep solids suspended in the water so the mixture can move through the pump, while the impeller and wear plates resist abrasive wear. It sits toward the smaller-motor end of the L family, offering a lower-powered option than the L60N for jobs that fit its flow and lift. Three-phase operation and the discharge arrangement need to suit the site as well as the material being pumped.

How the WEDA L50N compares

Rated at 7.4 HP, the L50N sits between the 5 HP WEDA L40N and the 12.1 HP WEDA L60N. Maximum flow progresses from 220 gpm to 350 gpm to 480 gpm, with head limits of 47 ft, 60 ft and 75 ft respectively. The L50N offers more flow and lift than the L40N, while the L60N extends both limits further in the WEDA pump range.

Questions about the WEDA L50N

Does the WEDA L50N have an agitator?

The L50N has a high-chrome agitator that helps keep solids in suspension. The abrasion-resistant impeller and wear plates handle contact with the mixture as it passes through.

How much head does it have?

Its maximum head is 60 ft and maximum flow is 350 gpm. Maximum flow and maximum head are not reached at the same time, so check the curve at the duty your installation requires.

What phase, discharge and weight should I plan for?

The pump uses three-phase power, has a 4 inch discharge and weighs 578 lb. Check the electrical supply and discharge connection before placing it in the slurry.
