NV NV 50/50-2.5-B-u2

Electroly loading type HB designed for pumping from underground drainage capacities of a mixture of water and dark oil products with solid inclusion.

design
A semi -loading unit of the type nv - an unit with vertical axial fluid input through a receiving pipe.

Upper Raspers-bearings 118 , GOST 8338-75, lower and medium supports - sliding bearings. Lubrication of rolling bearings-Litol 24 GOST 21150-87. The lubricant of two medium -sized sliding bearings is carried out through pipelines from an external source.

a change in the pump immersion is ensured by a change Lower suspension lengths. The place of exit of the shaft from the supporting plate is compacted by a reinforced cuff or end seal. A-65 antifreeze is fed to the end seal from the tank, fixed on the rack. The transmission of the torque from the engine to the pump is carried out through the elastic brown-fan coupling.
