a machine for moving hydraulic fluids through pipes under pressure. The term “soil pump” replaces the older term “suction hydraulic dredge,” a commonly used term in hydromechanization. Soil pumps are installed on suction dredge pumps and on floating and dry land dredging installations. The first soil pumps for construction and mining work in the USSR were made in 1935.
A soil pump is a single-stage, cantilevered, centrifugal pump with a single-sided intake. In the USSR, soil pumps are made with capacities up to 12,000 m3/hr and pressures of 0.9 meganewtons/m2. Further development of soil pumps will increase the standardization and unification of their junctions, increase resistance to wear of working elements through the use of new materials and coverings, and improve the form of the impeller and housing.
