1. What Is a Strainer Basket?
A strainer basket is the core filtering component inside a basket strainer. Its primary role is to capture solid particles larger than the mesh openings, such as sand, rust, pipe scale, and other debris. It helps protect downstream equipment like pumps, valves, and flow meters.
Unlike the outer basket strainer, which is simply the vessel or housing, the strainer basket determines the filtration precision.
2. Structure & Classification
Strainer baskets come in a wide variety of structural designs and specifications to suit different filtration needs:
By Layer Construction:
Single-layer basket – basic structure for general-purpose applications
Double-layer basket – added strength and durability for high-pressure systems
By Mesh Size:
Ranges from 5μm to 200μm
Smaller mesh = higher filtration precision
By Mesh Shape:
Square mesh – strong and easy to clean
Round (perforated) mesh – ideal for trapping larger particles
By Top Design:
Standard top – for standard vertical inlet/outlet designs
Beveled top – for angled or offset inlet configurations
3.Key Advantages of Strainer Baskets
Durability
Made of stainless steel or alloy materials, strainer baskets are robust, corrosion-resistant, and suitable for repeated use.
Eco-Friendly
Unlike disposable filter cartridges, strainer baskets are reusable, reducing waste and environmental impact.
Easy Maintenance
Simple structure allows for quick removal, cleaning, and reinstallation, minimizing downtime and labor costs.
Highly Customizable
Offers bespoke strainer baskets to match specific operating conditions, including pressure, temperature, and chemical compatibility.
