Pump U900/90 for its direct purpose to pump coal slurry, called coal pumps, and is mainly used for hydro-transportation of coal and sludge in mines and concentrators. In addition, the coal mine U900/90 has found its widespread use in quarries, the metallurgical, mining and processing and cement industries, as well as in the transport of other bulk materials.

Provided that the length of the pipeline is 200 meters and the conventional geodetic lift is not more than 5 meters, this model nominally produces 135 cubic meters per hour or 1,350 cubic meters per 10 hours of operation. The density of sand is 1.3 tons per cubic meter, the weight of extracted sand is 1755 tons. The extraction costs of 1755 tons of sand will amount to 2,500 kWh in 10 hours. The nominal consumption of diesel fuel for 10 hours of operation is 2,500 kW x 0.200 l/kW = 500 liters. From this calculation, we conclude: To extract 1755 tons of sand, 500 liters of diesel fuel is needed. The cost of mining one ton of sand is 500 liters/1755 tons = 0.285 liters per ton.
