Dexter's magnetic couplings have no seals, no leaks and no contamination. Because our magnetic couplings can transfer motion, force or torque across a solid barrier, no seals are required between the driving motor and the harsh or hazardous operating environment. Without a seal, there is no risk of leak or contamination.
Dexter can provide linear or rotational designs and functionality to handle the harshest of environments. We can scale to any device size or performance specifications you need.

Precise torque limitation
- torque limitation from 0,0 bis 1.000 Nm (synchronous clutch)
- easy and fast adjustable to your requirements
- application possible even at extreme high rotation
- speeds
- rated torque level is independent of age and operation
- infinitely adaptable to your requirements
- unlimited number of overload cycles
- absolutely abrasion-free
- rated torque level remains constant even at frequent
- overload cycles
Superior hygiene requirements:
- no abrasion
- no working material means or external supplies
- also available in high-grade steel
Superior transmission through the application of hysteresis clutches:
- constant and soft slipping at torque limitation
- ´soft starts´- smooth starting moments
- rated torque level remains constant even at overload status
- the shafts to be connected can be operated with different rotation speed

Magnetic Technologies Ltd. offers a complete line of coaxial and disc type magnetic couplings for transmitting torque.
• Torque range is from 0 to 2000 foot pounds.
• Speed range from 0 to 10,000 rpm.
• Couplings can transmit torque through a non-magnetic barrier, making them perfect for pumps, mixers, and actuators.

Overhead mounted agitator drive:
The overhead drive prevents the escape of any hazardous gases during agitation.
|
|
|
Using a bottom mounted agitator drive, the agitator is hermetically sealed, thus preventing any contamination of the product.
|
|
Magnetic couplings are a hermetically tight solution for pumps and agitators. Dangerous or precious media stay put in the closed system circuit. The power transmission (up to 315 Nm) occurs contact-free through magnets from the drive to the shaft running in the product. Magnetic couplings are thus the logical consequence for ecologically conscious buyers in the chemical industry.

Performance Spectrum:
- The broad spectrum of the DST standard construction range covers centrifugal pumps, rotating piston pumps, liquid ring pumps as well as agitators with differing torque ratings.
- Individual intermediate solutions are also available.
- Customer specific special solutions
Construction of DST permanent magnetic coupling:
- outer ring
- coupling enclosure (the cover is in Hastelloy from size 75/10)
- inner rotor completely encapsulated in 1.4571 stainless steel
- magnet material Sm2Co17
|
|
Conversion units can be retro-fitted in many areas, for example:
- PU machines
- Hydraulic applications
DST conversion units allow for the combination of the majority of different leading makes of pumps and drive motors.
We will evaluate specific applications to produce a functional combination, in order to utilise the advantages of "hermetically sealed" and "wear-free" in an optimum way.

Several types of magnetic rollers for can conveying systems are produced by Walker Magnetics
rollers for single transport
As part of our mass conveying program, we produce magnetic wide size rollers in any width. Rollers of 2500mm long are in regular production.
magnetic plates
All our rollers are built to complement our magnetic plates,
thus ensuring a good flow.
This range covers most of the requirements for modern can handling. For special applications, we produce tailor-made rollers, plates and curves according to customer's requirements.

Permanent Magnetic Rolls are used in steel pipes galvanizing process to remove steel pipes (and other steel shapes) from vats or pots filled with molten zinc. The drag out system usually consists of two magnetic rolls, side by side on a common shaft. Two lines of product can be handled alternately and simultaneously. Rows of Magnetic Rolls are in line on a heavy frame, which slops upward and away from the galvanizing tank. One unit is located almost directly over the end of galvanizing tank and the rest on and up the incline. The Magnetic Rolls are driven so that all Magnetic Rolls have the same surface speed. The operator, with the use of hook, lifts the end of a pipe from the molten zinc and place it on the lower side of the rotating first roll, at which time magnetic holding force of the roll firmly grips the pipe and propels it on and up the line of Rolls
- Standard and custom-designed sizes.
- Available with flat or vee grooved faces.
