Simplex & Duplex Type Strainer Simplex & Duplex Type Strainer

Simplex & Duplex Type Strainer Manufacturer in India

Metflow Engineers is a premier manufacturer, exporter, and industrial supplier of heavy-duty Simplex and Duplex fluid strainers. Designed to protect vital downstream equipment like high-pressure pumps, nozzles, and control regulators, our pipeline strainer assemblies systematically catch and isolate foreign debris, scale, and particulates. Whether your process allows for planned maintenance or demands continuous fluid flow with zero downtime, our ruggedly engineered line configurations deliver exceptionally low pressure drops (Δ P), high structural dirt-holding capacities, and enduring seal integrity.

Simplex Basket Strainers

Engineered for fluid processing pipelines where the process stream can be temporarily shut down or isolated for periodic element cleaning. Features a generous, single-chamber design with an extensive filtration surface area that reduces fluid velocity and limits initial scaling drops.

Single, high-volume element chamber
Ideal for batch operations or parallel bypass loops

Duplex Basket Strainers

Designed for mission-critical, continuous-flow process systems that cannot be shut down for element cleaning. Features a dual-chamber housing integrated with a robust flow-diverter valve system (plug or butterfly layout) that allows safe basket servicing while the alternate chamber remains fully operational.

Dual-chamber inline assembly with a diversion lever
Zero process downtime during mesh cleaning cycles

Simplex & Duplex Pipeline Strainer Engineering Baselines

Our complete range of industrial pipeline basket strainers is built to handle severe hydraulic friction, thermal spikes, and corrosive fluid processing media.

Metflow Mechanical Design Benchmarks

3:1 to 4:1 Open-Area Ratio

Internal chambers feature a generous internal basket surface area relative to the line cross-section. This ensures low initial pressure drops (Δ P) and longer operational run times before cleaning cycles are required.

Heavy-Cage Reinforced Elements

Mesh elements are reinforced with exterior rigid perforated steel backing to protect against complete structural implosion under sudden debris spikes.

Zero-Leak Diversion Seal

Our Duplex diverter mechanisms feature precision-machined, metal-to-metal or resilient seats. This design ensures absolute isolation of the servicing chamber, completely protecting operators from process fluid bypass.

Built-In Drain & Vent Ports

All housings come standard with plugged drain and vent connections, allowing for safe pressure relief and complete vessel draining prior to opening the covers.
