An industrial basket strainer is a type of industrial filtration equipment. It is used to remove solid particles from a liquid. The basket strainer consists of a perforated metal basket that is placed inside a housing. The housing has an inlet and outlet. Fluid flows into the basket strainer through the inlet. The solid particles are trapped in the basket, and the filtered liquid flows through the outlet.

Basket strainers are used in a variety of industries, such as food processing, pharmaceuticals, and chemicals. They are used to remove contaminants from liquids that will be used in these industries. Basket strainers can also be used to remove debris from cooling towers and boiler systems.

Basket filters are available in a variety of sizes and materials. The size of the basket strainer will depend on the flow rate of the liquid being filtered. The material of the basket strainer will depend on the type of liquid being filtered. Basket strainers can be made from stainless steel, bronze, or plastic.

Classification of Basket Strainer

The classification of basket strainers break down into two categories:

Based on the Mesh size

For strainers, there are three primary filtering groups:

  • For particles more significant than a specific size, use the coarse strainer
  • Medium Strainers are used to remove particles with sizes between 75 and 1905 microns
  • For particles less than 5 microns in diameter, Fine Strainers are used

 Based on the Method of Functioning

  • Simplex

These mono-chambered machinery pieces are used to remove particles and other debris from the running streamlet. These filters are not compatible with progressive processes because they require that the operation be halted for a time to alter or remove the basket strainer. One can easily detect if the basket is jammed by examining its entry and output pressure.

  • Duplex

This twin basket strainer consists of two simplex strainers linked by pipes and valves. These are essential for processes that need advanced function. They have two separate basket strainer units, each with a shared inlet/exit port. A duplex filter has the advantage that it does not require to be turned off when it gets jammed. It is equipped with an industrial butterfly valve that allows the flow to pass through either side of it without it being shut off.

Self-Cleaning Basket Strainer

This basket strainer is a higher-end version of the standard basket strainer. It’s also popular as a self-cleaning filter. Fluid will flow from the intake to this strainer, next to the filter’s output. The strainer will trap impurities until they clog. The clog clearing process begins immediately when the divergent pressure is at a certain point. The system will then backwash the strainer segment. The system will then block the inflow pipe and open another valve, allowing the debris particles to escape the filter system. These filters have two main benefits: It can reduce downtime by not having to take out the baskets for cleaning. This will result in lower maintenance costs, and gives experience of stress-free maintenance expenditures.

How Does A Basket Strainer Work?

Basket strainers are typically made of stainless steel or other corrosion-resistant materials. The baskets can be either round or rectangular. The size of the basket strainer depends on the amount of fluid that needs to be filtered. Depending on the application, basket strainers can be equipped with various meshes or screens.

The filter turns on when the water is filtered. It enters the strainer basket via the input, passes through the panel, and then withdraws the process discharge outlet to the pipe. The basket filter screen is clogged with particles and other solid contaminants. This steady flow causes more particles to be collected and slows down the filtering velocity.

On the other hand, the transported wastewater heads on constantly, closing and narrowing the filter outlet. This creates a pressure difference between the outflow and the inflow. When the differential pressure sensor detects that the intake pressure exceeds the specified value, the control system sends an electric signal to the operator. The transmission component then initiates the drive rotator to rotate and turn the shaft.

At the same time, the blowing port is unlocked, and waste is released from it. After blowdown clears the filter screen, the divergent pressure drops to the minimum value, and the system returns to its original filtering state. The filter includes a housing, several filter elements, a backwashing device, a divergent regulator, and other elements. The liquid flows into the lower chamber via the inlet when the filter is active. It then enters the room inside the strainer through the aperture in the diaphragm. It is an automatic filtration method that is innovative, efficient, and easy to operate.

Where To Put A Basket Strainer

There are a few things to consider when deciding where to put a basket strainer in an industrial setting. First, it is essential to ensure that the strainer is placed in an area with enough space for it. The strainer must be able to open and close fully without being obstructed by anything.

Second, the basket strainer should be placed in an area where it can be easily accessed for maintenance and cleaning. It is also essential to make sure that the filter is visible so it can be checked regularly.

Third, the basket strainer should be placed in an area where there is a good flow of water. This will help to ensure that the filter does not become clogged.

Overall, here are a few things to consider when deciding where to put a basket strainer in an industrial setting:

  1. Make sure that there is enough space for the filter.
  2. Ensure the strainer is visible and accessible for maintenance and cleaning.
  3. Provide a good water flow where the strainer is located.

How Often Should Clean A Basket Strainer?

Basket strainers are not like filters that need to be replaced regularly. They can be used indefinitely if they are cleaned and serviced regularly. A pipeline’s ability to function correctly depends on maintaining the pressure in high-flow systems. Pressure gauges can be placed on both sides to notify of any line anomalies. Removing the strainer from the pressure vessel and cleaning it is essential. Failure to properly manage the strainer can lead to a blockage that will require the strainer to be replaced.

To ensure its longevity, it is essential to maintain pressure readings. The system pipe that holds the basket strainer is to be dismantled and cleaned should be depressurized before attempting to clean it. Pressured strainers can cause damage or breakdown. After pulling the basket filter, exhaust the strainer and place it in a wash solution. To prevent the particles from sticking to the mesh, brush the strainer with a toothbrush. To avoid device shutdowns, may need to wash multiple screens.

A basket strainer should be cleaned regularly to keep it functioning correctly. Depending on the size and type of filter, it may need to be cleaned once a week or once a month. It is essential to check the filter regularly and clean it as necessary to prevent clogs and other problems.

If the basket filter is not cleaned regularly, it can become clogged with debris. This can cause the strainer to become less effective and can also lead to water damage. In some cases, a clogged basket filter can even cause flooding. Therefore, keeping the strainer clean and free of debris is essential.

Basket Strainer Parts And Accessories

Basket strainers are an essential part of many industrial operations. They filter out contaminants from liquids, gasses, or other substances. Basket strainers can be made from various materials, depending on the application.

The most important part of a basket strainer is the basket itself. The basket is usually made from metal or plastic and has holes that allow the liquid or gas to flow through while trapping contaminants. The size and shape of the basket will vary depending on the application.

Basket strainers also have a strainer body, which houses the basket. The strainer body is usually cast iron, steel, or plastic. Choosing a material compatible with the liquid or gas being filtered is essential.

Basket strainers come in a variety of sizes and styles. There are simple basket strainers that can be used for home applications, and more complex industrial models are designed for heavy-duty use.

There are a variety of parts and sections to basket strainers. These are listed below:

  • Covering for an Industrial Basket Strainer: The filter exterior cover holds the basket assembly in place.
  • Filter component: A washable screen with a basket strainer built in. This allows larger particles and waste to be removed from the pipe system. The basket sieving component comprises perforated plates with serial or staggered edges.
  • Handle It has a comfortable hold that makes it easy to remove and install the basket assembly.
  • Internal Cylinder: By changing the position, it closes the inlet/exit for cleaning out filthy elements.
  • Vent Valve: Employed for relief of pressure
  • Jamming indicator: It tells when the filter element must be substituted.
  • Blow off Valves: It removes particles and helps in cleaning strainer chambers.
  • Entry Port: It is where the tainted fluid from the procedure enters into strainer components.
  • Discharge Port: This is where the filter’s clean fluid exits.

Common Applications Of Basket Strainers

Because they can remove unwanted solid particles from fuel systems, transmission pipes, and fuel systems, basket filters are essential in petrochemical procedures. Filters are often used further down the feedline to purify and refine the substance.

The paint industry is another area that relies heavily on the basket strainer. The paint industry relies heavily on the basket strainer to ensure that the final product is free from unwanted substances and that it is easy to apply. Filtration systems are often used in certain situations to ensure that the paint is consistent and free from any lumps or molecules.

They are often used in conjunction with pumps and other mechanical equipment. Basket strainers can also be used in domestic applications, such as in sink drains to remove hair and other debris. Basket strainers are available in a variety of sizes and designs. The size of the strainer is dependent on the application. For example, basket strainers used in domestic applications are typically smaller than those used in industrial applications. The design of the strainer also varies depending on the application. Some basket strainers have a perforated basket that allows liquid to pass through while trapping debris. Other basket strainers have a solid basket that traps debris but does not allow fluid to pass through.

Basket strainers are made from various materials, such as stainless steel, bronze, and cast iron. The material is selected based on the application. For example, stainless steel basket strainers are often used in food and beverage applications to resist corrosion.

Basket Strainer In Different Industries

There are many commercial basket strainer to use in many different applications. Here is the list of other industries where strainer is used:

1. Refinery

The basket strainers protect machinery by mechanically eradicating particulates in liquids and other pipes utilizing a perforated mesh filtering screen or wire mesh filtering screening in a perpendicularly-oriented chamber. This is often used with flow meters, pumps, and compressors.

2. Waste Water Cleansing

Basket strainers can be for many water treatment purposes. They are usually placed in parallel pipelines upstream of machines and valves. Basket strainers are a prefilter to remove particles and prevent damage to downstream gear. This reduces maintenance costs and prevents downtime. Basket filters are great for ultra-fine filtering but still require significant pressure.

Basket strainers are often made from stainless steel. This not only ensures their durability but also makes them easy to clean. They have a wide filter surface and can hold large amounts of pollutants due to their basket design. Single-basket strainers can be disassembled and washed easily. However, multi-cylinder strainers are available, which reduces production time. Because the impurities to be removed should be considered, basket strainers are an effective and flexible filtering instrument for water treatment.

3. Production of electricity

The power generation sector requires water filtered by ion exchange to preserve machinery employed in downstream processes. This is possible with industrial basket strainers or procedure strainers that can handle the demands of large power plants.

4. Applications for Military Use

Navy ships use basket strainers to ensure that everything runs smoothly. Filter and training are necessary for everything, from weapon system unwinding to oil motor oil.

5. Irrigation

Large farms cannot simply turn on the water hose when it is time to water their crops. Instead, the incoming water is sifted through industrial strainers to filter out sand, pebbles, and other materials that could damage pump elements. Farmers can use catchment troughs or reservoirs on-site to increase their irrigation requirements.

6. Pharmaceutical

Basket strainers play an essential role in the pharmaceutical industry by preventing foreign matter from clogging process equipment. Keeping process equipment clean is critical in the pharmaceutical industry to ensure product quality and safety. In most cases, they are used as pre filters to protect downstream equipment such as pumps, valves, and heat exchangers. The pharmaceutical industries also use basket strainers to provide sterilization barriers between two process streams.

7. Manufacture and distribution of food

It doesn’t matter if a plant produces fruit juice, requires large amounts of clean water, and makes maple syrup. It should be capable of separating particles from the preliminary liquid. Depending on the liquid source, solids can be as big as lost plant stems or as small as minerals.            

Many strainers are used in food processing. To avoid clogging smaller meshes with large particles, it is best to use a more expansive mesh, and can get a suitable product by using the filters consecutively after the final straining.

Basket Strainer Maintenance Tips

Basket filters are essential to many plumbing systems but can be a bit finicky. If users are not careful, they can quickly become clogged, leading to many problems. That’s why it’s essential to keep up with regular maintenance on the basket strainer.

To determine if the basket needs to be cleaned or replaced, look for the pressure difference across the basket. If the screen becomes jammed, it will crack and need to be replaced.

Routine maintenance involves checking for leaks, washing the screen, or replacing it regularly. Regular use of the basket can cause foreign particles to build up, causing the pressure to increase.

When the differential pressure rises to unacceptable levels, washing the basket or replacing it is essential. This usually happens between 5-10 psi. It is not advised to allow the divergent pressure to rise by 20psi. This could lead the screen to break, which can lead to damage to downstream machinery.

It is easy to determine when the basket needs to be replaced by establishing pressure gauges at the inlet or outer ends of the Basket strainer. The Basket Strainer’s maximum pressure drop reaches zero, which indicates changing the screen. The basket structure and size determine the maximum pressure drop a Basket Strainer can tolerate.

How To Replace Basket Strainer

To replace the strainer basket successfully, one must follow the right approach. These guidelines will help to replace the Basket strainer.

  • Begin by unhitching the system.
  • The basket strainer should be carefully removed. Using the right tools, one can effortlessly remove the basket strainer’s flanged ends.
  • The top ring should be removed and one hand is needed to grasp the basket strainer. This will stop the basket strainer from spinning when the washer is removed.
  • Next, smoothen the bottom of the sink. For overseas items, move the sinkhole and smoothen it. However, remember to use a plastic substance. Avoid metallic substances, as they can cause damage to the surface.
  • Establish a new basket strainer. Next, terminate the ring and then the rubber or paper washers. Apply the adhesive (optimum binder) to the area in coalition with the sink.
  • Install the strainer correctly in the hole. Make sure to apply enough pressure to ensure that the strainer moves to the correct depth and stays attached. It must be removed if there is too much binder.
  • This is the right time to go back to the sink. The rubber seal should be assembled first, followed by the paper washer and the nut. Make sure to remove all binding substances. Rotate the system and tie it in a circular movement.
  • Now, tighten the nut but ensure that the strainer is securely placed. To put the tailpiece in place, pull the slip joint. It must be drawn to stabilize the system.
  • Gather the washers and trappers and make sure that everything is secure. Next, test the system.
  • Add water to the stopper and test it. Check for any leaks if still have problems. If there are no leaks, it means the process has done the right thing.

How To Choose Appropriate Basket Strainer

A different basket strainer might be needed for various purposes. Before deciding on a filter:

  1. Consider the precise requirements of the pipeline.
  2. Consider the temperature and pressure of the system and the type of fluid flowing (eroding, caustic, or other).
  3. Consider the size of the liquid particles and the frequency of cleaning and maintaining the basket strainer. One can also explore a duplex-style basket strainer that has two filter baskets and is equipped with a 3 way ball valve.

This system allows one basket to be cleansed and restored while the other can continue to flow.


In conclusion, industrial basket filters are essential to many industrial systems. They are used to remove contaminants from liquids and come in various sizes and designs. Industrial basket filters can be made of metals, plastics, or other materials and can be either manual or automatic.
