Magnetic separators remove iron particles from machine coolants. The device consists of high intensity magnets that remove not only ferrous particles but non-ferrous fines too, which act as a filter aid themselves. The magnetic separator ensures an uninterrupted flow of the coolant supply to machines for precision grinding. It can be used in both water-soluble and oil (neat) coolants.

Magnetic separators are reliable, powerful and portable. They can be used for a wide range of applications. They are highly recommended to be used as a pre-filter to limit contaminants reaching subsequent filtration equipment, if any.


A magnetic drum with close dense magnetic field is assembled on a non-magnetic SS shaft. We provide two types of drums – flat and finned. The finned drum-type consists of magnetic pole shoes that are projected out to form fins for better magnetic field alignment around the drum. The drum is rotated slowly by a geared motor drive. The non-magnetic SS trough holds the dirty fluid close to the drum. Magnetic particulates are picked up by the magnetic field and attached to the finned drum.

The filtration capacity of the drum type ranges from 50 to 1000 LPM (13 to 265 GPM).

An endless belt of magnetic candles is dipped into the dirty coolant tank such that the dirty coolant enters the core. Coolant flows slowly over the magnetic candles leaving ferrous materials on the candles. The belt is indexed to pull out the dirt-laden candles and rotate them at top to remove the dirt. The candles can be designed horizontally or vertically based on the type of application.

The filtration capacity of candle type ranges from 500 to 5000 LPM (130 to 1330 GPM).
