Atlas Copco WEDA D30L Submersible Dewatering Pump

The Atlas Copco WEDA D30L is the low-head, high-flow version of the 3 HP WEDA D30 family. The L impeller is tuned for high flow rate at low total head — ideal for surface water transfer, pond draining, and large-area site dewatering.

About the WEDA D30L

The Atlas Copco WEDA D30L moves drainage water where the job calls for more volume than the smaller D10N. It works submerged in a sump for construction dewatering and other clean- or dirty-water duties, avoiding the priming arrangement of a surface pump. Single-phase and three-phase versions share the same motor rating, but they have different flow and head limits. That gives the D30L a choice of electrical configurations without making the versions interchangeable: the selected pump still needs to match the site's supply and discharge route.

How the WEDA D30L compares

The 3 HP D30L bridges the 1.5 HP WEDA D10N and the 4.3 HP WEDA D40N. Its single-phase limits are 390 gpm and 62 ft, while the three-phase limits are 370 gpm and 58 ft. Use the figures for your phase version when comparing the WEDA pump range. Maximum flow and maximum head are not reached at the same time, so compare the curve for your chosen version with the actual duty.

Questions about the WEDA D30L

Are both phase versions 3 HP?

Both versions are rated at 3 HP in the 60 Hz range. Use the flow and head figures for the phase version you will connect.

What should I check for construction dewatering?

Check the water characteristics, required flow and total head alongside the discharge line. The D30L has a 3 inch discharge and a 0.28 inch solids limit, and construction drainage is a D-family application.

How heavy is the WEDA D30L?

Both phase versions weigh 44 lb. Check access to the sump and room for the discharge line before placing the pump.
