The compact design enables smooth, quiet operation and requires minimum maintenance. Double Run Conveyors or “grain pumps” cause less grain damage than a portable auger. They will move material into and out of grain storage structures, vehicles, and dryers. Double Run conveyors can replace a roof auger, transfer auger, dryer take-away auger, and even a permanently installed transport auger. Double Run conveyors come in 6″, 8″, 10″ and 12″ – with capacities of 2000 bushell per hour to 10,000 bushell per hour of dry corn.
