2. DESCRIPTION
2.1 Description
2.1.1 Architecture and operating principles
VLR motor-pumps are centrifugal, vertical multistage motorpumps with “in-line” suction inlets and delivery.
VLR motor-pumps are directly coupled to an asynchronous single
or three-phase motor with closed casing and external ventilation.
VLR motor-pumps are not self-priming and need a priming
procedure. VLR motor-pumps can be equipped with oval or round
flanges.
