Demonstrations of A.R.T. Pump in Tacoma, WA. T1012 A.R.T. Pump System: 10-inch Auger Accelerator with 12-inch product line Product Line: 12-inch diameter black poly sewer line-well over a quarter mile in length. Butt-jointed and welded. Approximately 1200 ft. floating on a lake. Power Supply: Electric Motor- running the auger. 50 H.P. turning at 1175 RPM.  Cummins Diesel engine with 2:1 gear reduction box running a Roots lobe-type blower. The Engine develops 350 H.P. at 1800 RPM. The Blower develops 13, 500 CFM at 900 RPM. We run the engine at 500 RPM with the 2:1 reduction. We are operating the blower at approximately 1/3 capacity. The picture below illustrates the A.R.T. using light weight pipe floating on the water. This demonstrates that the products is not in contact with the interior of the pipe, but floating on a cushion of air. This also prevents any vibration disturbance on the water resulting in visible waves. | Product: System was designed to handle these products specifically. System has the capability in this configuration of moving the following tonnage per hour:
Dr. Grant Wood, retired professor of Mechanical Engineering at Western Washington University, has attended several demonstrations and has given us the following calculations on performance. Corn – 180-190 tons per hour 92-95 MPH travel speed Coal – 190-210 tons per hour 92-95 MPH travel speed Pea Gravel – 375 tons per hour 97-125 MPH travel speed Virtually NO Pressure in the line Virtually NO Product degradation Cost Factors: $3.00 per hour electricity $6.00 per hour diesel fuel Cost to move pea gravel over ¼ mile in quarry using conveyors or front-end loaders is at least five times the cost of using our pump system.
