1. Main Features of Basket-Type Strainer:

Large basket volume, can hold a large amount of impurities, and can be maintained without shutting down the system;


2. Advantages, Disadvantages, and Applicable Operating Conditions of Different Types of Strainers:


2.21 Advantages of Basket-Type Strainers

① Large filter basket volume, extremely strong dirt-holding capacity, can operate for a long time without cleaning;

② Supports large diameter and high flow conditions (DN25~DN1200 can be manufactured);

③ Can be made with a quick-opening structure, cleaning the filter basket can be completed in minutes by opening the cover, some can be equipped with a bypass to achieve non-stop cleaning;

④ The filter screen is subjected to uniform stress, not easily damaged under high pressure and high flow rate;

⑤ Can be equipped with multi-layer filter screens and magnetic filter screens, suitable for viscous media.

 

2.22 Disadvantages of Basket Type Strainers

① Large overall size, occupies a lot of space, and cannot be installed in narrow pipe corridors

② Cost is much higher than Y-type filters;

③ Sludge easily accumulates at the bottom when installed vertically, and viscous media tend to accumulate and clump;

④ Uneconomical for small pipe diameters.

 

2.23 Main Application Areas of Basket Type Strainers

① Chemical raw materials, wastewater treatment, large-diameter circulating water pipelines;

② Crude oil, heavy oil, slurry, and industrial fluids with high impurity content;

③ Power plant circulating water, water treatment systems, and front-end filtration for wastewater treatment pump stations;

④ Coal chemical industry, chemical fiber slurry, coatings, and viscous liquid filtration;

⑤ Main pre-filter for large pump sets and heat exchangers.


3. Selection Recommendations:

3.4 For high-flow-rate systems with many impurities and long-term continuous operation, a Basket-type Strainer is recommended.

3.5 For viscous chemical slurries and wastewater, a Basket-type Strainer is recommended.

3.6 For viscous media containing a large number of solid particles, a Basket-type Strainer is recommended.
