2.1 Description

2.1.1 Architecture and operating principles

VX motor-pumps are centrifugal , vertical multistage motor-
pumps with "in-line" suction inlets and delivery.
VX motor-pumps are directly coupled to an asynchronous single
or three-phase motor with closed casing and external ventilation.
VX motor-pumps are not self-priming and need a priming
procedure. VX motor-pumps can be equipped with oval or round
flanges.
