About this file
This is a technical drawing and bill of materials for a 20-inch AWWA C207 Class D discharge mixed flow pump manufactured by Cascade Pump Company for Triangle Pump & Equipment under Purchase Order P23301. The project is for the U.S. Army Corps of Engineers (USACE) McNary Lock & Dam dewatering pumps.
The pump is rated at 12,000 GPM with a 40-foot head, operating at 1,190 RPM with a single stage. It is driven by a 200 HP VHS electric motor (3 phase, 60 Hz, 460 volt, 1,200 RPM) with a non-reverse ratchet and 1.15 service factor constant speed driver. The pump assembly has a total dynamic weight of 18,960 LBS (pump dry weight 8,100 LBS, dynamic water weight 6,000 LBS, motor weight 4,860 LBS) and includes nozzle load specifications with down thrust of 8,880 LBS. The pump uses product lubrication and dimensions approximately 50 feet-8 inches in total height with a 33.5-inch diameter. The bill of materials specifies 316 stainless steel (CF8M) castings for suction and discharge bowls and impeller, duplex stainless steel for shafts and couplings, nitrile rubber bushings, and Flexaseal MLC3 multi-lip cartridge seals. Spare parts provided include extra bowls, bushings, shaft components, line shaft couplings, packing box bushings, and fifty percent of flange fasteners. The drawing was released to production on July 15, 2024 (Revision A) with final release on November 21, 2023.
