About the WEDA D70H

The Atlas Copco WEDA D70H is a high-head submersible drainage pump for clean or dirty water. Its 18 HP motor and higher-lift hydraulics suit jobs where the discharge route demands more head than the D70L can provide, including mine, quarry and construction drainage. The pump works submerged, without a surface-pump priming arrangement. The D70H puts the emphasis on lift; check its curve for the flow available at the head your installation requires.

How the WEDA D70H compares

The 18 HP D70H reaches 205 ft maximum head, above the 166 ft limit of the 11.5 HP WEDA D60H. Moving to the 31 HP WEDA D80H raises that ceiling to 247 ft. Compare the flow at your required head across these models in the WEDA pump range.

Questions about the WEDA D70H

How much head and flow does it have?

In the 60 Hz range, the D70H reaches 205 ft maximum head and 660 gpm maximum flow. Maximum flow and maximum head are not reached at the same time, so use the curve to check the required operating point.

Should I choose WEDA D70H or WEDA D70L?

Choose the D70H for its higher head limit or the D70L for its higher flow limit, after checking the curve for your duty. Both are rated at 18 HP, but the D70L reaches 1,230 gpm maximum flow and 129 ft maximum head.
