Duplex Basket Strainer Manufacturer in India
Process equipment such as pumps, heat exchangers, meters and control components can be affected by weld scale, rust, suspended solids and other debris carried through a pipeline. A duplex basket strainer uses two filtration chambers so one basket can remain in service while the other is isolated for cleaning or maintenance. Speciality Valve is the best Duplex Basket Strainer Manufacturer in India, offering duplex basket strainers for continuous-flow industrial and process applications.
Duplex Basket Arrangement
Two independent basket chambers are incorporated into the strainer body with a changeover arrangement. This allows the operating flow path to be transferred from a loaded basket to a clean basket without requiring complete process shutdown, subject to the system design.
Twin basket chambers
Changeover mechanism
Removable filter baskets
Drain connection
Vent or pressure-release arrangement where required
Flanged or screwed connections
Differential-pressure monitoring provisions where specified
The basket opening should be selected according to the particle size that must be retained and the allowable pressure loss.

Filtration Performance Factors
Particle Size: Determines the required basket opening.
Solids Loading: Influences cleaning frequency.
Flow Rate: Establishes the required filtration area.
Pressure Drop: Must remain within the allowable system limit.
Viscosity: Affects flow through the basket.
Basket Area: Determines available flow capacity.
Differential Pressure: Provides an indication of basket loading.
A larger filtration area can help reduce pressure loss and extend operating time between cleaning intervals.
Industrial Applications
Oil & Gas: Shields pumps and equipment from pipeline contaminants.
Refineries: Strips solids from compatible streams.
Petrochemical Facilities: Shields downstream equipment.
Chemical Processing: Compatible with compatible liquids.
Power Generation: Used in cooling-water and utility systems.
Water Treatment: Protects pumps and equipment from suspended solids.
Marine Systems: Applicable to compatible seawater and utility services.
Maintenance Advantages
Continuous filtration capability in suitable changeover arrangements
Reduced process interruption during basket servicing
Higher debris-holding capacity than compact pipeline strainers
Removable baskets for inspection and cleaning
Multiple body and screen materials
Suitable for different pressure configurations
Supports protection of downstream equipment
