НОУ Series

Designed for pumping out crude oil and oil products that leak out of pipeline pumps and for their injection into the suction pipeline of an oil pumping station.

Electrically driven, vertically suspended, wet-pit end-suction diffuser multistage segmental centrifugal pumps in cantilever design, with single flow radial impellers, a separate discharge pipe, a motor stool and a can (outer casing). The inner casing (a withdrawable rotating assembly) of ring-section design may be installed in an existing vessel or a sump* to be submerged in the medium pumped. The rotor is carried by medium-lubricated radial plain bearing at the balance drum and intermediate bearing and a grease-lubricated top thrust and radial antifriction bearing (of two ball bearings). No shaft sealing is required. NOTE: *Overall and mounting dimensions of the withdrawable element mounting plate (pump cover plate) are made specific after the Customer’s submittal of data on fitting dimensions of a tank mouth flange.
