The NIKKISO centrifugal canned motor pump is specifically used in chemical industry 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. The pump meets the specification of the API-685 standard.
In use, the centrifugal canned motor pump implements flow rates up to 1,200 m³/h and works with pressures up to 40 bar (at 50 Hz).
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.
The NIKKISO Non-Seal is a compact centrifugal canned motor pump with integrated motor that covers high-pressure and high-temperature applications.
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.
High serviceability
Since the fluids lubricate the sliding parts, no additional lubrication is required. This gives the pumps a high degree of serviceability.
Low space requirement
Due to the integrated structure of the centrifugal canned motor pump, it only needs very little space and is ideal for applications in which a small footprint is required.
Quiet and low-vibration
The pump is quiet and has low vibration. It is extremely weather-resistant and has good dust protection.
Low maintenance costs
The pump has only low maintenance costs due to the relatively low number of components and the real-time monitoring of the bearing wear.
