CANNED MOTOR PUMPS
The NIKKISO centrifugal canned motor pump is specifically used in chemical industry for transfer and circulation tasks, particularly for supercritical, hazardous and toxic fluids as well high pressure and high temperature applications.
The pump and motor are integrated in the sealed leak-proof structure of the centrifugal canned motor pump. The pump meets the specification of the API-685 standard.
The stator has a two-layer structure, consisting of the stator liner, stator band, and extremely tight terminal strip, allowing for a higher degree of safety. With the pressure raised by the impeller, the liquid is sent to the discharge side. A part of the fluid also reaches the motor and is used to lubricate the bearings and cool the motor of the centrifugal canned motor pump. Then, this part is lead back through the extraction openings on the shaft (standard model) for the intake side.
Integration of the motor
Directly integrating the canned motor into the centrifugal pump does not only ensure environmental protection, but also safety at the plant. All parts of the pump are also designed for easy and fast maintenance. Therefore, you can minimize unproductive down times.
Very good high-pressure characteristic
Compared to solenoid driven pumps, the NIKKISO Non-Seal centrifugal canned motor pump features considerably better high-pressure properties. Therefore, it is ideally suited for transfer and circulation tasks with critical or hazardous fluids.
DIN EN ISO 2858 – End-suction centrifugal pumps (rating 16 bar)
NIKKISO centrifugal canned motor pumps meet the dimensions and nominal outputs in accordance with DIN EN ISO 2858. This means that NIKKISO fulfills the requirements of a standardized chemical pump, which makes it easier to exchange existing pumps.
