DAKOTA PUMP INCORPORATED P. O. BOX 947 - MITCHELL, SD 57301 - PHONE (605) 996-6636 - FAX (605) 996-6067 sales@dakotapump.com DP I Sewage Pump Station Design Information What city or authority will the station be located? What is the actual site name? (street, road, ect...) What are the pump conditions? ___________ GPM @ ____________ TDH What power is available? _____ wire/_____ phase/60 hertz/______(120/208/230/460) What is the proposed grade elevation? _______ What is the proposed slab elevation? ______ What type of pumping station is best for the application? Flooded suction with dry pit non-clog pumps Vertical builtogether or vertical flex coupled pumps Typically the most efficient for flows 100 GPM and higher Positive suction head required Longest practical design life (20+ years) Widest pump condition range More easily applied to special requirements (flowmeters, ect...) Most reliable with low maintenance costs Vacuum-Priming Wet Well Mounted Fiberglass enclosure Maximum suction lift of 16' Semi-Buried (If high suction lift is greater than 16') Vertical builtogether pumps Lower initial and installation costs, however, more costly to maintain More accessible than flooded suction stations Self- Priming Wet well mounted Fiberglass enclosure Buried can station Shallower bury than flooded suction due to self-prime capacity Less efficient than flooded suction Pneumatic Ejector More efficient for flows under 100 GPM Designers and Fabricators of Water & Wastewater Pumping Stations No wet well required What size pump chamber? _______ (7,8,9,10,11,12, 13, 14 or obround) foot diameter _______ What is the desired inside height What diameter entrance tube? 36 inch or 48 inch Is a maintenance lift an option?
