Features of Strainers
1. Material Matters:
  • Stainless Steel :  The workhorse material, offering excellent corrosion resistance, durability, and ease of cleaning.
  • Duplex Steel :  For high-pressure and corrosive environments, where strength and resilience are paramount.
  • Super Alloys :  When dealing with extreme temperatures, harsh chemicals, or abrasive particles, specialized alloys provide an extra layer of protection. We provide INCONEL - 625 and MONEL - 400 for strainers on request.
  • The choice of material depends on factor such as fluid compatibility, temperature, and the corrosive nature of the environment.
2. Design Diversity:
  • Basket Strainers :  The classic cylindrical basket housed in a pressure vessel, ideal for capturing large debris.
  • Y-Strainers :  Compact and efficient, with a Y-shaped body facilitating easy cleaning and flow management.
  • T-Strainers :  Offering additional filtering surface area with their T-shaped body, suitable for viscous fluids.
  • Self-Cleaning Strainers :  Utilizing backwashing or rotating mechanisms to automatically remove captured debris, minimizing downtime.
3. Filtration Finesse:
  • Mesh Size :  Determines the size of particles captured, ranging from coarse meshes for heavy debris to fine meshes for micron-sized particles. We provide various types of straining elements, including mesh screens, wedge wire screens, perforated plates etc. choice depends upon particle size, pressure, fluid type, and required level of filtration.
  • Multi-Stage Filtration :  Combining different mesh sizes in a single strainer for progressive filtration and optimal efficiency.

Applications of Strainers

Strainers find applications in various industries where the removal of solid particles from fluids is crucial to maintain equipment efficiency and protect downstream processes.

1. Water Treatment :

Strainers are used in water treatment plants to remove debris, sediment, and larger particles from raw water before it undergoes further treatment processes.

2. Chemical Processing :

In chemical industries, strainers are employed to filter out solid impurities, preventing damage to pumps, valves, and other sensitive equipment. They play a critical role in maintaining product quality and process efficiency.

3. Oil and Gas Industry:

Strainers are used in the oil and gas sector to filter contaminants from hydrocarbon fluids. This helps protect downstream equipment, such as compressors and turbines, ensuring smooth operation and preventing damage.

4. Food and Beverage Processing:

Strainers are utilized in the food and beverage industry to filter liquids, removing particles that could affect the quality and safety of the final product. Sanitary strainers are often employed in these applications.

5. HVAC Systems:

Strainers are installed in heating, ventilation, and air conditioning (HVAC) systems to capture debris and sediment from the circulating water, preventing clogs in pipes, valves, and heat exchangers.

6. Power Generation:

Power plants use strainers to protect critical equipment like pumps and condensers from impurities present in cooling water. This ensures the efficient and uninterrupted generation of power.

7. Pulp and Paper Industry:

Strainers are employed in the pulp and paper industry to filter out fibres and other contaminants from pulp slurries, helping maintain the quality of the paper production process.

8. Pharmaceutical Manufacturing:

In pharmaceutical production, strainers are used to filter liquids and remove particles that could compromise the purity of medications and other pharmaceutical products.

9. Mining and Minerals Processing:

Strainers play a role in the mining industry by filtering liquids used in mineral processing to remove solid particles, preventing equipment wear and ensuring efficient processing.


These applications demonstrate the versatility and importance of strainers in maintaining the integrity and efficiency of various industrial processes across different sectors. The specific type and design of strainer chosen for a particular application depend on factors such as the type of fluid, particle size, flow rates, and system requirements.

Strainer Types and their details

Advantages of Basket Strainers

1. Efficient Particle Removal :  

The design of basket strainers allows for effective removal of a wide range of particle sizes, contributing to enhanced system performance.

2. Low Pressure Drop :  

Properly designed basket strainers offer low pressure drop, minimizing the impact on overall system efficiency.

3. Ease of Maintenance :  

Removable baskets simplify maintenance activities, reducing downtime during cleaning or replacement procedures.

Duplex Strainers:

A duplex strainer consists of two filter baskets or elements. Each basket can function independently of the other. In normal operating conditions, fluid flows through one of the baskets while the other basket remains the standby. This allows continues filtration without interrupting the process. Duplex strainers are provided with isolation valves that allow operators to divert the flow between the two baskets. This is useful during maintenance and cleaning procedure. When one basket becomes clogged or requires cleaning, the flow can be switched to the standby basket without stopping the overall process.
