Industrial Coolant Filtration Systems

Hydraulic Vacuum Filters

Introduction and Operation: A perforated top vacuum chamber is placed at the bottom of dirty coolant tank. Machine outlet lets dirty coolant in this tank.

A pump sucks coolant through filter paper laid on top of vacuum chamber, leaving dirt on filter paper. Pump suction generates vacuum increasing dirt layer thickness & hence finer filtration.

Pneumatic Vacuum Filters

For finer processes of material removal like grinding and honing, a finer filtration level is required. If the fluid is not filtered to the desired filtration level, the particles leave a mark on the surface. Normal gravity filter does not give the desired filtration level. Also the media consumption is very high.

In such cases Vacuum filter is the ideal solution. With the help of vacuum, finer filter media can also be used for very fine operations.

Compact Vacuum Filters

For finer processes of material removal like grinding and honing, a finer filtration level is required. If the fluid is not filtered to the desired filtration level, the particles leave a mark on the surface. Normal gravity filter does not give the desired filtration level. Also the media consumption is very high.

In such cases Vacuum filter is the ideal solution. With the help of vacuum, finer filter media can also be used for very fine operations. In some cases due to lack of space, a compact solution is required.

Eco Type Paper Band Filters

Conveyor Type Paper Band Filters

Compact Band Filters

Gravity filters take a large shop floor area. When there is restriction in space available a Compact band is suggested. As the dirty fluid is transferred using a pump, this filtration system can be placed away from the machine also.

In this filter the filter paper is held between a pair of sealing discs & a permeable support belt. Dirty fluid is dropped in the trough formed with filter paper at the bottom.

Cartridge Type Pressure Filters

Pressure filters housing are pressure vessels in which cartridge filters / elements are assembled. These elements can be of various micron rating from 300 micron to 1 micron and suitable different type of fluids like water based emulsion, cutting oils or washing fluids.

The filter housing are manufactured in carbon steel or stainless steel and tested for 2 times the working pressures.

Flat Bed Multi Plate Pressure Filters

For finer filtration we need to use finer filter media. But such media offers resistance to flow and hence cannot be used in gravity filter. If we could increase the differential pressure across the filter media, we could achieve finer filtration. A flat bed pressure filter does exactly that.

Dirty fluid is fed under pressure in to inlet manifold. It is distributed equally in plates. Filter papers clamped & supported between plates separate the dirt & form a layer (cake). This effects finer filtration.

Mesh Upflow Drum Filters

When the process generates large quantum of chips a mesh drum filter comes in handy. Veeraja mesh drum have a unique seal design which increases the life of seal and is very maintenance friendly.

Fluid with chips drops in cavity outside a mesh drum. It moves in the drum trough fine mesh, by gravity, leaving the chips on the mesh. A scraper conveyer, wrapping the mesh drum & scraping the outside cavity, carries the chips to a bin.
