Audited Supplier (1)Features
The NMB series is used successful in many applications
worldwide. The can is made from PTFE-seal insulated
rings and a slotted outer can, which reduces EC-losses to
a minimum. They are designed for increased safety and
energy savings. Thus they can handle large motor torques,
high speed and high pressure.
(2)Advantages
•Magnetic coupling for applications acc. to API 685 (similar to API 610)
• Hermetically sealed
• No contact of torque transmitting elements
• No maintenance necessary
• High efficiency can (insulated rings and slotted outer can) for lowest eddy current losses (approx. 2 % of motor power)
• Increased safety and energy savings compared to solid Hastelloy® cans
• Sliding bearing optional
(3)Functional description
The power transmission occurs contact-free through
magnets from the drive shaft to the product wetted output
shaft. Between the two rotating parts is the can wich is
bolted to the container.
(4)Operating range (see note on page 1)
