The pumps are designed for pumping, as well as pumping oil, oil products with a temperature of minus 15 ° C ...+80 ° C, water from buried tanks. The buried tanks of the normal row have a different container and different depth of the deepening, and the latter cannot exceed 15 meters. Pumps can be used at any reservoir of a normal row due to changing the number of links in a pressure column that allow you to change the distance from the supporting surface of the pump to the lowest point of the suction pipe.
The pumps are centrifugal, vertical, sectional, with a transmission shaft, with an axial supply of pumped liquid, with hydraulically unloaded from axial efforts with working wheels, with a drive from an electric motor. The supports of the pump rotor 24NV18x1 are: the upper support-instant rolling bearing operating on liquid oil lubricant, the lower and intermediate hydrodynamic sliding bearings operating on the pumped environment.
