The Nikkiso centrifugal canned motor pump is specifically used for the most demanding applications for transfer and circulation tasks, particularly for supercritical fluids. The pump and motor are integrated in the sealed leak-proof structure of the centrifugal canned motor pump. Directly integrating the canned motor into the centrifugal pump ensures safety at the plant and environmental protection, as well as it only needs little space and is ideal for applications in which a small footprint is required. All parts of the pump are also designed for easy and fast maintenance, therefore minimizing unproductive down times.
