Coolant filtration systems
Govoni adopts different filtration systems according to the requirements of the client and a series of associated advantages :

  • longer life of the coolant
  • reduction of maintenance costs
  • reduced consumption of materials to dispose of
  • reduction of wear and tear of tools
  • contained dimensions
GRAVITY BAND FILTER:

gravity band filter

Due to gravity the coolant containing suspended particles enters the tank containing the filtering nonwoven fabric, deposits solid particles as it passes through and flows out clean.
The progressive clogging of the fabric increases the water level above the filter until the level sensor reaches a maximum value. This activates the automatic set up of a new layer of fabric of the drum to start a new filtration cycle.
The coolant is purified, collected in the tub and then returned to the machine tool through a pump to be used again.
The maintenance required by this system includes only the replacement of the roll of filter fabric and periodic cleaning of the sensor.

ADVANTAGES:

  • high filtration power
  • optimization of the consumption of the filter fabric
  • quick replacement of the filter fabric
  • low power consumption

FLOW RATE:

  • emulsion: from 50 to 500 l/min
  • cutting fluid: from 25 to 250 l/min
ROTATING DRUM FILTER:

rotating drum filter

Due to gravity, the coolant enters the filtering unit consisting of a drum activated by a dredging system which supports a permanent sheet made of stainless steel; the liquid deposits the slag and falls into the containment tank. This system allows for a very high degree of filtration since it is self-cleaning, thanks to a washing system that cleans the cake on the surface by means of the same purified liquid.

ADVANTAGES:

  • high filtration capacity
  • absence of maintenance
  • absence of waste materials

FLOW RATE:

  • emulsion: from 50 to 1000 l/min
  • cutting fluid: from 25 to 600 l/min
KALAMIT MAGNETIC SEPARATOR

kalamit magnetic separator

This is an autonomous system that uses a strong magnetic field generated by special steel discs. The coolant is channelled through these discs which collect all the iron particles contained in the liquid using magnetic force, but also most of the non-ferrous particles through the mechanical action of the rotating drum.
The system is kept clean thanks to a scraper blade that sweeps the sludge and discharges it through a special chute.

ADVANTAGES:

  • high filtration capacity
  • minimum maintenance
  • absence of waste materials

FLOW RATE:

  • emulsion: from 50 to 1200 l/min
  • cutting fluid: from 25 to 700 l/min
CENTRALIZED FILTERING PLANT

In the presence of numerous machine tools, it is possible to create a centralized filtration system that allows for the liquid coolant to be purified through a single filtration unit and then collected in a storage tank. From this it is reintroduced to machines for reuse through a pumping system.
The filtration system installed may vary according to the flow rate of the liquid, filtration needs, the fluid to be treated etc.

When possible, self-cleaning filtration systems are also installed that do not require maintenance and that do not involve the disposal of waste materials.
