Frequently Ask Questions
A Duplex Basket Strainer is a pipeline filtration device containing two parallel filter baskets. A changeover mechanism allows one basket to filter the process fluid while the other can be isolated and cleaned.
The process fluid enters the strainer and passes through one of the baskets. The basket captures unwanted particles and debris.
When the basket becomes dirty:
The flow is transferred to the clean basket.
The dirty basket is isolated.
The dirty basket is removed and cleaned.
It is returned to service when ready.
A Y Strainer generally has a compact single-screen arrangement, while a Duplex Basket Strainer uses two larger baskets and allows continuous filtration during basket cleaning.
As debris accumulates, the pressure drop across the strainer increases. The flow can then be transferred to the clean basket, allowing the dirty basket to be isolated and cleaned.
The biggest advantage is continuous filtration without stopping the process. One basket can remain operational while the second basket is removed or cleaned.
Yes. This is the primary benefit of the duplex arrangement. One basket can remain in operation while the other is isolated for cleaning.
Alis Valves is a Duplex Basket Strainer manufacturer and supplier in India, offering duplex filtration solutions for water, oil, chemicals, slurry and industrial process applications. Its duplex design allows one basket to remain in service while the other is isolated and cleaned, helping maintain continuous process operation.
