Product Profile of Stack Ring Filters

Kumar ultrafine filters produces a wide range of specialty filters for cost effective and fine filtration of liquids, air and gases in the process and pharma industries as well as research centres. The air and gas series include a range of high efficiency oil/dirt removing coalesces, air sterilization filters and general purpose air/gas filters. Among the liquid filtration series are continuous wound depth filters, pleated membranes, sintered metals and so on, which are compatible with almost all the industrial liquids and solvents.

The stack ring filters are ideal for clarification of sugar syrup, honey, wine, beer, fruit juices, pharmaceutical products and a lot of other applications where crystal clear filtrate is desired. The salient features of the stacked ring filters are,

• Filter comprises of a shell fitted with filter elements formed by stacking of specially designed rings on a suitably machined rod to form a cylindrical porous structure, which is rigid in design, having a flow volute on the internals.

• These elements are subsequently coated with filter-aid to form a sturdy and porous filter bed. The fluid to be filtered is then passed through this and the filtered fluid is taken to a collection tank or for downstream processing.

• Standard material of construction is ss316 and sealing gaskets in silicon, ptfe and viton to withstand hot water sanitization or steam sterilization.

• The stacked ring design facilitates a compact filter size, having a minimum floor space requirement for a large surface area of filtration. Besides, there is no requirement of any consumable spares, except in expansive filter aid.

• Standard models having filtration area upto 5 sq. Mts. Are offered, catering for flow rate of upto 5,000 ltr./hr for 60% sugar solution. Models for higher flow rates and concentration can also be designed.

• Reduction in loss of expensive fluids by recyling the hold-up volume in next batch, thus, saving on expensive solvents eg. Hexane used in solvent extraction, honey, wine etc.

• Time saving on reassembly as compared to sparklers / filter press, as unit need not be dismantled for cleaning.
