NGPN-M pumps-centrifugal, horizontal, spiral type, single-stage with biased wheels, with an axial connector of the housing, with a bilateral supply of the pumped environment to the working wheel, interdort (wheels are located between bearing supports). The use of prefected wheels increases the cavity qualities of the pump. Radial loads from the rotor are perceived by supporting rolling bearings with autonomous annular lubricant.
To perceive the residual axial force of the rotor, a double radial-console rolling bearing is used. As the end seals of the shaft, single end seals with additional (backup) seal from the atmosphere are used. To clean the bolt oil from mechanical impurities, supplied to the chambers of end seals, hydrocyclone separators are used.
Designed to ensure the necessary backwater before oil main pumps. Can be used for pumping oil in other technological systems of NPS or other industry facilities.
