About the WEDA D80N

The Atlas Copco WEDA D80N moves large volumes of clean or dirty drainage water with a 31 HP motor and a 6 inch discharge. It works submerged for mine, quarry and construction dewatering, without the priming arrangement of a surface pump. Compared with the D80H, its hydraulics provide a higher flow limit and a lower head limit. The D80N gives priority to water volume over the extra lift offered by the D80H, so check its curve against the flow and head your discharge system needs.

How the WEDA D80N compares

The 31 HP D80N reaches 1,560 gpm maximum flow against 1,230 gpm from the smaller 18 HP WEDA D70L. Its maximum head is 147 ft. At the same motor rating, the WEDA D80H instead reaches 247 ft, with a lower 670 gpm flow limit. The D80N offers the higher flow ceiling in this comparison within the WEDA pump range.

Questions about the WEDA D80N

Will it deliver max flow at max head?

Maximum flow and maximum head are not reached at the same time. The 1,560 gpm and 147 ft limits describe different points on the curve, so check the flow available at your required head.

Can it handle mining drainage?

The WEDA D family covers mine and quarry drainage. The D80N uses three-phase power and has a 0.47 inch solids limit, which should be checked against the water being removed.

What discharge and weight should I plan for?

The pump has a 6 inch discharge and weighs 389 lb. Check that there is access to position the pump and connect the discharge line.
