Import Duplex Strainers — Buy in Bulk from Supplier in India

Harsha Filters supplies duplex strainers that feature two basket filters linked in parallel through a single‑handle changeover device. The design incorporates a pair of balls housed in one housing, allowing the operator to shift flow from one basket to the other with one lever movement. This configuration provides continuous filtration while one basket is being cleaned. The company markets the units for chemical processing, water treatment and oil‑field applications.

The supplier does not list the exact alloy, but duplex basket strainers are typically fabricated from stainless steel grade AISI 304, which tolerates aggressive media and temperatures up to 110 °C. Standard sizes for such strainers range from DN 80 to DN 150, with a pressure rating of PN 16, matching the requirements of most medium‑pressure process lines. A common mesh specification is 80 µm, offering finer particle capture than the 100 µm mesh used in some variants. These industry norms ensure reliable performance in continuous‑operation plants.

Harsha Filters indicates that it is an authorized manufacturer of duplex and basket strainers, but provides no specific MOQ or packaging details. Buyers should request sample drawings and confirmation of any certifications, such as ISO 9001, before committing to volume purchases. Typical import terms include FOB or CIF from the nearest Indian port, and the equipment is usually packed in wooden crates with protective padding. Procurement engineers and plant managers looking for robust filtration solutions often select this design for its ease of maintenance.
