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.

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.

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.

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.

TYPICAL APPLICATIONS
EFS
Standard size housings available with 30 (590), 60 (250), 100 (149), and 150 (99) mesh (micron) reusable, stainless steel filter cartridges. Units measure 11.25" long and feature a 1" NPT intake and dual 1" NPT discharge ports (3/4" reducers provided).
FEATURES
Graymills Superflo filters are designed to overcome the typical pressure drop and reduced flow due to clogging that occurs with ordinary filters. A permanent magnet suspended over the intake port traps ferrous particles which find their way into the fluid, and diffuses the flow outward into the filter screen flutes. Filtered material is trapped on the inside of the removable/reusable stainless steel filter cartridge. To clean, just remove the cartridge. All the contaminants come out with it. Self draining. No wasted fluid or messy leftovers to deal with. Stainless steel filter cartridges are available in four different mesh screens.

Drop-in magnetic separator filters, designed for fluid tanks and reservoirs, pull fine particles out of fluids and hold them until the unit can be cleaned and dropped back in. Used in tanks or other containers having low to moderate flows. Direct blast of fluids over unit is not recommended.

These magnet filters are used to filter ferrous particles from liquids and they are frequently used in hydraulic circuits and cooling systems. The magnet system is constructed from ceramic magnets and the unit is built into a stainless steel (AISI 304) casing. For cleaning, the magnet system is simple to remove by undoing several quick-release fasteners. A special double-walled version is available for use in heated pipeline systems (for example, separating ferrous particles from molten chocolate and cheese). Bakker Magnetics magnet filters are available in a number of versions for special applications. For situations where extremely stringent requirements for ferrous separation have to be met and/or tiny ferrous particles (m region) have to be extracted, a system can
be fitted with Neodymium magnets (add "/01" to the article number). A special version is available for use in systems with high pressures. Sanitary models are also available for applications in, for example, the food industry. For processing large quantities of raw materials, heavy-duty versions can be supplied. These versions have a processing capacity from 1000 to 8500 l/min.

As pre-cleaners or main cleaners for subordinate applications and magnetisable chips, magnetic filters offer a good and reasonably priced filtration method.
Turbo Separator AG produces magnetic filters with flow rates of 100 - 400l/min.
Depending on the application area, these magnetic filters can also be built up in cascades.
Magnetic filters from Turbo-Separator can be installed as integrated components of a system or built on as accessory products.
Special requirements call for special solutions - we shall implement your wishes, with unconventional solutions if need be! (SE magnets)

Bunting General-Purpose Grate Magnets provide a properly configured, high-density magnetic field to trap and hold ferrous fines, fragments, and small metal objects. Stainless steel tubing and frames are welded into strong, integral units. They can be installed - or simply laid - inside hoppers, housings, and bins - and easily removed for cleaning. Grates are built for low-abrasion applications and should measure at least twice the size of your outlet opening, so as not to restrict product flow.
General-Purpose Grate Magnets consist of multi-polarity 1-inch diameter cartridges arranged on 2-inch centers. They're available in round, square, and rectangular configurations from 4" through 36" in size. They can be ordered without baffles for freer flowing materials, and with angular baffles for maximum magnetic protection.
