Patent

CA 2137100

A pumper system is adapted to enable pumps to be switched between parallel operation, for the high flow conditions normally desired for in-situ pigging operations within a line to be cleaned, and series operation, for the high pressure conditions needed in the event the pigging device becomes obstructed in the line.

Cette invention concerne un système de commande permettant de faire fonctionner des pompes en parallèle pour réaliser les débits élevés normalement exigés par les opérations de nettoyage de pipelines par piston racleur et en série pour augmenter la pression dans l'éventualité où le piston racleur se coince à l'intérieur du pipeline.
