Simplex Basket Filter Housings
Simplex Basket Filter / Strainers, these are mechanical devices for the efficient removal and retention of solids and other foreign material from flowing fluids and gases. They do this by means of a strainer basket housed within the unit. Basket strainers incorporate larger filtration areas than ‘Y’-Type strainers and similar strainers and thus provide minimal pressure losses, improved flow rates, greater dirt holding capacity and longer service life.
Basket Filters / strainers are used in a vast range of applications where flow can be interrupted to allow the removal of the basket for periodic cleaning. They are usually mounted horizontally into the pipeline, however on fabricated units, line connections can be orientated to suit customer requirements. Minor modifications can also be made to enable the installation into downward flow vertical pipelines.
The central part of the unit is the strainer basket which removes and retains the harmful contamination. The basket is secured via a spring-loaded handle which is compressed by the strainer cover. Baskets are manufactured from perforated plate and, for finer degrees of filtration, baskets are lined with mesh linings which can be either permanent fixtures or removable.
For fine filtration down to 1 – 2-micron, special basket assemblies can be provided where only the middle insert needs to be replaced as required. Baskets can be supplied in high quality Stainless Steel which is cleanable. As with all strainers, great emphasis is placed upon the filtration area available in each unit. For greater filtration areas, pleated baskets can be provided.
Optional features can be accommodated to most units and include :
Magnetic basket assemblies
Pleated baskets for high filtration areas
D.P gauges and switches c/w alarms
Flanged D.P. , vent and drain connections
Special coatings and linings
Special basket assemblies for fine filtration
Special reinforced baskets for high collapse pressures
Vent and drain valves
Steam jackets (fabricated units only)
A wide selection of materials available including :
Carbon Steel
Low Temperature Stee
Various grades of Stainless Steel, Gunmetal, Aluminum Bronze, Cunifer (90/10), Duplex and Super Duplex Stainless Steel, 6Mo Stainless Steel, Alloy 20, Alloy 28, Inconel, Monel, Hastelloy and Titanium.
Duplex Basket Filter Housings
Duplex Basket Filters and Strainers provide continuous process flow service, allowing cleaning or replacement of a basket without interrupting the process flow. Duplex Filter/strainers can be supplied as either cast or fabricated units which are normally installed horizontally into pipelines, however, fabricated units can be orientated to suit your requirements. Duplex strainers comprise two filter chambers, one duty and one standby, each housing either single or multi baskets.
The two filter chambers are interconnected by a valve changeover system, which diverts the flow from one chamber to the other without interrupting the process flow. There are several different valve arrangements that are used to divert the flow and these are detailed below.
Duplex Basket Filters are used to clean liquid, viscous and gaseous media. They offer perfect protection against undesirable particles and are cost effective in protecting your piping, industrial valves and plants.

Basket Strainers
Basket Strainer is a type of mechanical filter used to remove unwanted particles and Impurities from fluid stream. It consists of a cylindrical or spherical body with an inlet and an outlet, housing a removable basket-like straining filter element.
Features :
Removable Basket:
The basket strainer’s straining element is removable, allowing for easy cleaning and maintenance. The removable basket also facilitates inspection of the collected debris.
Construction Materials:
Basket kind of strainers are commonly constructed from durable materials such as stainless steel, carbon steel, or exotic alloys, depending on the application requirements. This ensures their longevity, resistance to corrosion, and compatibility with various fluids and operating conditions.
Perforated or Mesh Lining:
The straining element of a basket kind of strainer can have either perforations or a mesh lining. Perforated baskets are suitable for applications with larger particle sizes, while mesh-lined baskets provide finer filtration for smaller particles.
Catalyst / Carbon Recovery Systems
Catalyst Recovery Filter for polishing and removing solids, activated carbon and catalyst from reaction mixtures and also hydrogenation reactions. The solids are either remove from the fluid streams or re slurry and send them back to the system. The solids can be obtained in slurries with 30 – 40% moisture or with the help of dip pipes in the candle filter, catalyst with 10-15% moisture can be obtained.
Sintered Metal Filters uses outside-in filtration for filtering precious metal catalysts in hydrogenation reactions. The candles are back washable and regain original flux after every batch. The mechanism is either to remove the catalyst from fluid streams and filter with zero-holdup recovering all the chemicals or re-slurry and send them back to the reactor.
Features & Benefits
Absolute Filtration :
Clear Liquid after filtration – NO recirculation of the liquid required
Sintered Powder media
No Loss of precious metal Catalyst – improvement in recovery. Savings for companies
Closed system:
Helps reduce operator exposure to hazardous materials, and extends catalyst life for active catalysts like Pt, Pd, Ni , Rh, Ra-Ni etc.
Operation Terminology
System consists of a number of equally sized pressure vessels each containing membrane metal filter elements arranged on a tube sheet or headers. The vessel performs the specific functions of filtration, in-situ reverse flow, gas assisted discharge of collected catalyst and when required, an in-situ soak to re-slurry the catalyst if required.
The mechanism of filtration is a direct interception of catalyst particles on the surface of the Imported Sintered membrane metal filter. The cake builds up from 3 mm to 25 mm depending on the type of catalyst being used. The cake resistance of different catalysts can also vary with operating conditions like viscosity of the liquids, density, temperature, pH etc.
The ZERO HOLDUP bottom design for Batch operations and when the catalyst is to be sent for regeneration after every batch, ensures that complete liquid is removed from the vessel and zero holdup is maintained. This is very important for API / Chemicals manufacturing where GMP does not allow mixing of batches nor any liquid holdup is allowed.
At the end of each filter cycle, solids are backwashed off the inside of the elements and discharged as a concentrated slurry to send back to reactor or collected as wet cake in collection vessels.
