LEWA NIKKISO Non-Seal - Centrifugal Canned Motor Pump
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 NIKKISO centrifugal canned motor pump is an ideal solution for transfer and circulation tasks in the chemical industry. It can be used to pump hazardous, toxic and supercritical fluids.
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.
Good reasons for a NIKKISO Non-Seal® canned motor pump
The NIKKISO Non-Seal pump is a canned motor pump that covers high-pressure and high-temperature applications.
- Health and safety-oriented : NIKKISO Non-Seal pumps’ airtight design protects operators against exposure to substances that are dangerous to health. And the pumps are designed to handle explosive or flammable fluids, and other aggressive fluids.
- Simple installation and maintenance : Compact design combined with a low number of required components enables simple installation and maintenance. Feeler gauges and shims are no longer necessary. And since there is only one shaft, alignment is a thing of the past.
- Small & compact, low space requirements : Pump and motor integration means space is used especially efficiently. With minimal base space requirements, set-up costs are reduced.
- Eco-friendly : NIKKISO’s leak-free design prevents product loss and pollutant emission into the atmosphere. The best option for addressing worldwide concerns for the environment and increasingly stringent regulations.
- Unique E-Monitor : NIKKISO offers highly reliable canned motor pumps. In order to fit predictive maintenance programs, NIKKISO Non-Seal pumps also have the E-Monitor feature for local bearing monitoring.
- Quiet and low-vibration : A fully encapsulated system without a motor fan or exposed bearings enables low-noise and low-vibration operation. Perfect alignment between the motor and pump also reduces system vibration significantly.
