NTSN-E, 20NDSN-M

Applications of the pumps НЦН-Е: for boosting the pressure of oil-field produced (formation) water to be injected into the petroliferous pools (for secondary oil recovery) as booster waterflood pumps; for handling triethylene glycol; for loading mazout (fuel oil) and light oil (motor gasoline, kerosene and diesel fuel) into tank wagons at the oil refinery terminals. May be used as booster pipeline pumps for НМ series pipeline pumps used for handling crude oil; for drawing off crude oil from the flow tanks (oil treating vessels) of the central process facility.

Electrically driven, horizontal foot- or semicentreline-mounted, between-bearings, single-stage, axially split volute casing centrifugal pumps with a double entry radial impeller. The rotor is carried by the grease-lubricated or oil-bath lubricated antifriction bearings. Shaft sealing: by mechanical seals

20 НДсН-М designed for delivering crude oil to the main pipeline pumps as booster pumps to ensure their cavitation-free operation. Suitable also as a loading pump for filling light products into tank wagons at the refineries and as an oil transfer pump in the tank farms.

Electrically driven, horizontal foot-mounted, between-bearings, single-stage, axially split volute casing centrifugal pump with a double entry radial impeller. The rotor is carried by grease-lubricated spherical roller bearings. Shaft sealing: mechanical seals with organized leakage drain.
