Atlas Copco’s WEDA electric submersible pumps make their debut on the American market with a new range for professional users. The new additions to the range are 1hp and under, c-UL-us approved, 60Hz single-phase drainage, sludge and residual pumps. They come in two voltage variants, 115V and 230V, and join the 50Hz range that is already popular in Europe and in the rest of the world.
