Atlas Copco Drainage Pumps — WEDA Electric Submersibles
The WEDA family drops into the sump and gets to work: D-series drainage pumps for groundwater and site dewatering, and L-series slurry pumps when the water carries real solids — compact electric submersibles sized from basement sump to mine face.
The short version
Clear-to-dirty water: the WEDA D drainage series. Sand, fines, and slurry: the WEDA L slurry series. Both are configured to voltage and size by phone or on the product page. Air-powered alternative: the DOP 15 diaphragm pump.
The WEDA Range
WEDA D Series Drainage Pumps
Foundation excavations, tunnels, and underground development: compact electric submersibles from sump-size D04 up through high-head D80 configurations, in single- and three-phase 60 Hz builds.
Choose it when: groundwater and rainwater need to leave the excavation on electric power.
Key specs
WEDA L Series Slurry Pumps
When the water is half ground: agitator-style slurry submersibles built to move sand, fines, and bentonite-laden water that destroys drainage pumps.
Choose it when: slurry transfer, wash-bay sumps, and solids-heavy dewatering.

Drainage Pump Questions
WEDA D or WEDA L?
D for water — even dirty water — where the job is volume out of the hole. L when solids are the point: sand, fines, slurry. If the pumped fluid would settle into mud in a bucket, you want the L.
How do I size a drainage pump?
Flow needed, total head (lift plus friction), and available power — three numbers, one phone call. We configure the right WEDA size and voltage from there.
What about air-powered pumping?
If a compressor already runs your site or the fluid is abrasive slurry in a hazardous spot, the DOP 15 diaphragm pump pumps on air alone.
How fast do they ship?
Configured units are quoted and ship promptly — call 1-888-883-5144 with flow, head, and voltage and we will confirm availability same day.
Dry Hole, Moving Job
Flow, head, voltage — three numbers and we will have a pump on the way.
