NPV Series Vertical Can, Diffuser
Designed for delivering crude oil or oil products to the main pipeline pumps to ensure their satisfactory suction performance (cavitation-free operation). Suitable also as mixing pumps to transfer oil in tank farms and as loading pumps to fill end products into tank wagons at the oil refineries.
Electrically driven vertically suspended, end-suction single- or multistage (according to the required head) diffuser centrifugal pumps equipped with an inducer. The major pump components are a can (outer casing) and a withdrawable rotating assembly with a motor stool. Upgraded versions (identified with “M”) feature a barrel-shaped delivery casing. The pump rotor is carried by the top thrust and radial bearing (comprising two ball bearings) and the bottom medium lubricated plain bearing. Shaft sealing: by mechanical seal. Made in compliance with Transneft’s General and Specific Engineering Requirements (OTT and STT resp.).
