The alloy applications of SmCo magnets can be divided into two categories. The first one can be called 1:5 series. There are one SM atom and five co atoms. Their magnetic field strength ranges from 16 to 25 mgory. 2:17 series are composed of two samarium atoms and 17 cobalt atoms. Some cobalt atoms can be replaced by excessive metal atoms, such as iron and copper. The magnetic force of these alloys is in the range of 20-32 mgoe.

Magnetic couplings are employed in seal-less, leak-free magnetic drive pumps used to handle volatile, flammable, corrosive, abrasive, toxic or foul smelling liquids. The inner and outer magnet rings are fitted with permanent magnets, hermetically sealed from the liquids, in a multipole arrangement.

The inner and outer magnetic rotors are locked together by magnetic forces and work as a synchronous coupling. The permanent-permanent magnetic couplings create neither slippage nor induction current during rotation. When excessive torque is applied, the magnets will decouple, they will not recouple unless the pump is stopped.

Permanent magnetic couplings offer an efficient, leak-proof, cost effective, and more reliable alternative to various conventional sealing methods.

How does magnetic coupling work?

We will help you with your order. Usually we ask for the following information.
1) Product material,size, grade, coating, quantities required. etc..if available, a sketch or drawing with dimensions and tolerances.
2) Delivered magnetized or unmagnetized? Magnetization direction?
3) Information on what you want to use the magnet for?
