The \u003cstrong\u003eAtlas Copco WEDA D81H\u003c\/strong\u003e 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.\u003c\/p\u003e\n\n\u003cp\u003eThis 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.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003ctd\u003e\u003cstrong\u003eWEDA D81H\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePart Number (SKU)\u003c\/th\u003e\n\u003ctd\u003e3081621333\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFactory Designation\u003c\/th\u003e\n\u003ctd\u003eWASD81.00H T 460V D 60HZ C 4\" NPT CL PC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eRated Output Power\u003c\/th\u003e\n\u003ctd\u003e31 HP (23 kW)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMax.
