NGPN-M Series Inducer Double Flow Axially Split

НГПМ Designed to ensure the necessary suction head (a greater NPSH available) for the main pipeline pumps. May be used also for pumping crude oil in other process systems at the pump stations or at other industrial projects.

Electrically driven, horizontal foot-mounted, between-bearings, single-stage, axially split volute casing centrifugal pumps with a double entry radial impeller and an inducer on each side to reduce the NPSH value. Rotor radial forces are taken up by the radial antifriction bearings with self-contained oil-ring lubrication. The residual axial thrust of the rotor is absorbed by two single row angular-contact antifriction bearings mounted back to back. Shaft sealing: by single mechanical seals, each provided with an auxiliary (safety) seal on the atmosphere side. Cyclone separators are employed to clean handled oil extracted at the top connection from contaminants and solids and to supply cleaned liquid for sealing the mechanical seals. Made in compliance with Transneft’s General and Specific Engineering Requirements (OTT and STT resp.).
