Basket Industrial Filters

Basket Filter
The open area ratio in Basket Filter refers to the amount of free open of the Industrial strainers & Industrial Filters. It is the ratio of the open area through the Basket Filter to the cross sectional area of the pipeline. A well designed Basket Filter ought to have an open ratio of at least 4 to 1. Anything less may cause excessive pressure drop. The ratio is calculated with a tidy basket & as the basket begins to clog the ratio will drip. Unless there is a wide safety margin the area through the basket may quickly become smaller than the pipe area. This will reduce flow through the Basket Industrial Filters & necessitate frequent cleaning. A small open area ratio also means the holding capacity of the basket is small - an important consideration if the amount of solid matter to be removed is large.

A second consideration in Basket Filter choice is ease of basket removal. Since a basket Industrial Filters is used where cleaning may occur often, it stands to reason that the basket ought to be able to be removed and replaced as basically as feasible. A yoke type cover will accomplish this. The Basket Filter cover is held down by a clamping yoke which is sturdy to hold full line pressure and yet, which can be quickly loosened or tightened by hand. Bolted covers are also furnished with Basket Filters and they cost less than yoke covers. However, every time they are handled their nuts must be taken off and replaced the same as with a flange. This is time consuming and, in the long run, pricey.

A wide selection of basket perforations & mesh sizes ought to be obtainable. This is necessary to cope with the great range of particle sizes which the sterner may be called on to remove. Another item to look at in picking a Basket Industrial Filters is compactness of design. Is the Basket Filter unnecessarily bulky or tall? In lots of industrial areas space is at a premium & the less room a Basket Filter takes the better. This is true on board ships where every square foot counts.

A basket Industrial Filters ought to be obtainable in several materials of construction, the same as valves. A lovely manufacturer ought to offer Basket Filter made of iron, bronze, steel, and stainless steel. Iron, of work is the least pricey. Bronze and steel cost about six times as much as iron and stainless steel costs about two times as much.

Since it costs the least, iron ought to be the first choice of a Basket Filter user & for this reason it is by far the most popular material. Forged iron has nice corrosion resistance in water service. It is also used with plenty of non-aqueous materials such as paint, fuel oils, & plastics. Iron Industrial Filters are usually supplied with stainless steel baskets. The disadvantages of iron are its inability to stand thermal or mechanical shock, and it~~s susceptibility to corrosion in plenty of applications.

Bronze is the preferred material for marine services. Bronze Filters are widely used for handling sea water & also brackish or saline ground waters. The best basket material in these areas is Monel. Stainless steel won't resist sea water as well as Monel. Another use for bronze Basket Filter is where the product can be contaminated by iron, but the cost of stainless steel is prohibitive. A lovely example is handling of liquid sugar. The material is sensitive to iron pickup. Stainless steel is dear. Bronze is a lovely compromise & is therefore used. Bronze may even be used with mildly corrosive materials where iron is unsatisfactory & stainless might be pricey.

Carbon steel Basket Filter are used chiefly in the oil and petrochemical industry. They have excellent resistance to mechanical or thermal shock and these are important considerations in the event of a fire. Most oil refineries won't permit iron piping parts for this reason. Steel Basket Filters are also used for higher pressure applications because of their great strength. Basket material is usually stainless steel.

Stainless steel Basket Filter, of coursework, are used where high corrosion resistance or where freedom from contamination are necessary. They are popular in the chemical, food, and pharmaceutical industries. Naturally, stainless steel Basket Industrial Filters ought to have stainless steel baskets.

Basket Filters

Glando Basket filter is manufactured in simplex and duplex type construction with suitable material. Duplex Basket Filter provide ease of cleaning the element without interruption of the process. Two simplex basket filters connected with a pair of three way ball valve with a common single handle makes a this type of filter. By rotating this common handle flow is diverted from filter in operation to the standby idle filter.

The clogged filter element can be cleaned and made ready for next change over. Simplex/ Duplex type Industrial Filters are available in fabricated and cast construction. Simplex type filters in cast construction are called pot strainers or bucket type Industrial Strainers. Filters are manufactured up to diameter of 48” NB size and filtration down up to 5 micron. Low press drop, large dirt holding capacity, ease & low cost of maintenance are some special features of Glandofilters.

We offer Basket Filters that are marked by premium quality. The Industrial Basket Filters are manufactured using the sophisticated technology to ensure enhanced performance. Basket filters are mainly used for liquid filtration in industries such as petroleum, chemical industry, food, beverage, water treatments, etc. As to external dimensions and filter rating, we may also provide products per customers’ requirements. Consequently, we are among the reputed Basket Air Filters Manufacturers based in India.

Basket filters are the low cost answer to a variety of liquid clarification needs. The basic filter is floor-mounted, in-line pressure vessel consisting of a tubular housing in which the filter media is supported by a 316 stainless steel basket.

Industrial Filters are offered in separate models with flow rate up to 250 gpm. filters consist of two single filter units connected in parallel to 3-way valves. filters are usually rated for the same flow as single filters. That's because in most applications one filter unit is valved off stream while the other continuous filtering.

Self Cleaning filters

Self cleaning filters are available in some standard models to choose from for different flow rates. They are also designed & fabricated as per requirement. Size manufactured is up to 6” NB and below and filtration achieved is down to 40 micron. Element of self cleaning filters can be cleaned by one rotation of outside handle or knob. The dirt over the surface of element is brushed down by scraper blade & collected at bottom and can be drained out.

Automatic Self-Cleaning Filters are manufactured with assembly of motor & gear to rotate the filters element for continuous cleaning. The element of self cleaning filters has very high mechanical strength and can with stand a very high differential pressure & ease of cleaning element are some special feature. This type of filter is suitable for most liquids with suitable material of construction.

The modern factories handling huge volumes of Cooling Water, Process Water & Waste Water puts high emphasis on the filtration of water, as the same has to be recycled to main processes.

Industrial Filters "Self Cleaning Filter" employs Welded Wedge Wire Candles as filter media, which offers  the unique feature of back washing of the filter media through the automated PLC & timer circuit, guarantees uninterrupted filtration using the same filtrate solution.

The fluid to be filtered flows via two ends into the inside of the non-clogging Welded Wedge Wire candles with inverted radial construction. In this way the solid particles to be filtered out are retained over the whole length of the inside of candles so that full filtering area is uniformly used. As compared to filtration operation the back-flushing time is only few seconds.

Industrial Filters are available with different filter elements to suit different filtering requirements and filtration degrees. These all purpose filters are made with different engineering plastic materials that can be suited for mechanical strength and chemical and corrosion resistance.
