Magnetic grate separators in housing MRZ
The liquid magnetic separator MRZ is designed to separate magnetic iron contamination from liquid substances (such as coolants and emulsions for various machining operations).
Design of the magnetic grate for liquids
The basic elements the magnetic grate separator in housing consists of are magnetic tubes (made from stainless steel). While the liquid material flows aroung the magnetic tubes, a very strong magnetic field (generated by the neodymium NdFeB magnets inside of the tubes) traps all metallic particles on the surface of the tubes. The sets of tubes are placed one above the other inside of the housing (or one behind the other – in case of a vertical position of the tubes) and the first set of tubes consists of one tube less. The grate sieve - created in this way – is in a very intensive contact with the flowing materia, can capture even the smallest ferromagnetic impurities and guarantees an extremely high separation efficiency. For best results the inlet part of the separator can be equipped with dispersion cones that disperse the material flow over the magnetic tubes.
Which way is the magnetic grid for liquid products cleaned?
The metal particles captured on the magnetic tubes migrate to the rear of the tubes where they remain protected from wash-off until the tubes are cleaned. During the cleaning the magnetic cores are pulled out of the tubes (either manually or pneumatically) into the upper part of the separator housing. The captured magnetic impurities fall off spontaneously. Thanks to the encased version of the magnetic grate separator the neodymium cores are totally maintenance-free.
If you use our magnetic grate separator in housing, you will improve the quality of your final products, you will be able to use the coolants in a repeated way and in particular we will help to protect your expensive machinery. The dimensions as well as the design of the magnetic grate separator in housing can be adjusted to client's needs.

We produce magnetic separators in these three levels of magnetic induction
The MRZ is designed for open-flow systems with a lower level of ferromagnetic contamination — typically cooling emulsion tanks on machining centres. The inline separator MSP-MC is suitable for closed pipe circuit installations, while the automatic MSP-AC is recommended where the material is heavily contaminated and manual cleaning would be too frequent. We will help you choose based on the specific parameters of your application.
The magnetic grate separator MRZ captures ferromagnetic particles from just 1 micrometre. We offer three levels of magnetic induction: standard (17,000 G at the core), with the highest pull-off force of up to 176 N (16,100 G at the core) and with the highest magnetic induction of 18,700 G at the core — the latter is designed for the most demanding applications with very fine contaminants.
The standard model range covers widths from 100 to 450 mm (heights 100 to 400 mm), specifically models MRZ 100/2N to MRZ 450/5N. We adapt the separator dimensions to your cooling tank or specific spatial requirements — custom manufacturing is a standard part of our offering.
Cleaning is carried out by moving the neodymium magnetic cores into the upper enclosed section of the separator — either manually via a control lever or pneumatically — after which the captured metallic contaminants fall away by themselves. The magnetic cores require no maintenance thanks to the housing design. Optional deflector baffles are also available to direct the flow of material towards the magnetic tubes and increase separation efficiency.
The MRZ is used primarily in engineering for cleaning cooling emulsions and oils used in milling, turning, grinding, polishing and drilling. It is also used in the automotive industry, chemical industry, ceramics and glass industry and paper industry — wherever costly production equipment needs to be protected from damage caused by metallic contaminants and the service life of coolant fluid needs to be extended.
We carry out free tests of your material on our magnetic separators and guarantee results within three days. We will visit your facility, survey your process and propose a specific solution — after installation we will ensure commissioning, operator training and authorised service throughout the lifetime of the separator.
MRZ separators are manufactured in full stainless steel with authorisation for welding pressure equipment under PED 2014/68/EU and certification according to EN-ISO 3834-2, EN 1090-2 and standards EN 13480 and EN 13445. For customers in engineering and the chemical industry where separators are exposed to aggressive fluids, this certification guarantees verified weld quality and long-term equipment durability.
