Industrial fluid systems rely on effective filtration to protect pumps, valves, heat exchangers, and other downstream equipment from debris and sediment. In applications where shutting down a system is not practical, duplex strainers allow maintenance and basket cleaning without interrupting flow.
Tate Andale, Inc. manufactures heavy-duty industrial twin basket strainer systems for demanding industrial environments. These duplex strainers are built for continuous-duty service and are available in multiple configurations, materials, and pressure ratings for a wide range of industrial operations.
Tate Andale supplies industrial basket strainer products used across water treatment, marine systems, power generation, mining, and chemical processing facilities where dependable filtration is required.
Continuous Flow Duplex Strainer Design
A duplex strainer is essentially two simplex strainers connected by an integrated set of valves. Our duplex strainers and filters are suitable for processes with high particle loading, and processes where it is not permissible to interrupt the process flow.
Our build to order duplex strainers and filters are available in a number of different materials of construction including iron, steel, stainless steel, bronze, aluminum, and various high nickel alloys.
We usually recommend the straining media to be one half the diameter of the component that requires protection from debris. For example, 1/4’’ tubes in a heat exchanger should be protected by a strainer basket with 1/8’’ perforation. Oversizing the straining media could allow debris to foul critical equipment, while under-sizing the straining media could cause the strainer basket to clog with excessive frequency.
Industrial Basket Strainer Models
Tate Andale manufactures several duplex strainer models to support different flow rates, materials, and operating conditions.
Tate Andale Model R and S Twin Basket Strainer
The Model R and S series features heavy-duty cast iron construction for industrial service applications. These duplex/twin basket strainers are manufactured in the USA and meet American Iron & Steel and Buy America requirements.
These units are commonly used in systems requiring continuous filtration and simplified maintenance access.
Tate Andale Model AL and AH Twin Basket Industrial Strainer
The AL and AH series uses a sliding gate valve arrangement that helps reduce wear during chamber changeover. Key features include:
- low pressure drop
- side-entry baskets
- quick opening covers
- optional manual backflush capability
- semi-automatic and automatic operation options
- magnet assemblies
- zinc anodes for saltwater service
The AL model supports pressures up to 125/150 PSIG, while the AH model supports up to 250/300 PSIG. Sizes range from 4” to 24”.
DU-200 Series — Industrial Dual Strainer System
The DU-200 Series is available in fabricated steel, stainless steel, and exotic alloy construction for demanding industrial environments. Manufactured in the USA, these systems provide material flexibility for applications involving higher temperatures, corrosion exposure, or specialized process fluids.
Tate Andale Model ID Twin Basket Industrial Strainer
The Model ID series uses a tapered plug valve arrangement that helps reduce bypass leakage and valve wear during operation.
These industrial twin basket strainer units are available in sizes from 3/4” through 8” and are suitable for:
- oil
- fuel
- gasoline
- paint
- water
- industrial process fluids
Large drain connections and quick opening covers simplify servicing and debris removal.
Material and Build-to-Order Options
Tate Andale duplex strainers are available in:
- cast iron
- cast steel
- stainless steel
- bronze
- aluminum
- high nickel alloys
The company also provides build-to-order manufacturing for facilities requiring specific perforation sizing, pressure ratings, valve configurations, automation features, or backflush systems.
Applications Across Industrial Systems
Tate Andale duplex strainers help protect:
- pumps
- cooling water systems
- heat exchangers
- fuel handling systems
- intake water systems
- chemical processing lines
By removing debris before it reaches downstream equipment, these industrial basket strainer systems help reduce maintenance frequency and support stable system operation.
