276 feet of head out of a 31 HP drainage pump. The Atlas Copco WEDA D81H pushes up to 890 gpm through a 4 inch NPT discharge and passes solids to 0.47 inch, which places it between the D80H and the 40 HP D91H in the WEDA D range. It is the high head build of the D81, so it trades flow for lift. If you need volume instead of pressure at this power rating, the D81N is the same 23 kW motor turning a different hydraulic end at 1,630 gpm and 167 ft.
This is one of the models Atlas Copco built around their patented Wear Deflector Technology, with a closed impeller running auxiliary vanes and a lower diffuser carrying wear deflector vanes. The point of all of it is that the pump can be readjusted back toward factory performance as the hydraulics wear, instead of being run until output falls off and then replaced.

Key Features
- Built-in starter and motor protection. The D81H carries its own DOL or soft starter and motor protection on board, so there is no separate control panel to buy, mount and wire. Atlas Copco fits this across the D10 through D91 models.
- Wear Deflector Technology. Closed high-chrome impeller with auxiliary vanes, polyurethane upper diffuser, and a lower diffuser with wear deflector vanes.
- Readjustable hydraulics. The 55 HRC high-chrome cast iron impeller and adjustable diffuser let you bring performance back as parts wear.
- Double mechanical seal in a stainless steel cartridge, serviceable on site rather than at a shop.
- External oil screws so an oil check does not mean opening the pump.
- Dry running capability from an oversized, heat dissipating motor design.
Where it fits
Deep excavation and stage dewatering, underground and open pit mine face dewatering, quarry sumps, intermediate pumping stations, and long discharge runs where friction loss eats the head a normal-head pump can produce. Handles clean through dirty water to a specific gravity of 1.1. For sludge or abrasive slurry, the WEDA S and WEDA L ranges are the correct families, not this one.
