Duplex Basket Strainer Manufacturer in India
Two baskets, one changeover — clean filters without stopping the pump.
Duplex vs simplex
A simplex basket needs a bypass or shutdown to clean. A duplex strainer has two chambers and a diverter so flow never stops. Essential on fuel oil to burners, compressor lube systems and continuous process cooling.

Frequently asked questions
What is a duplex filter / duplex strainer?
A twin-basket strainer with changeover so filtration continues while one basket is cleaned. “Duplex filter” in industrial search usually means this — not duplex stainless steel.
When do I need duplex instead of Y-strainer?
When the line cannot stop for cleaning or dirt load is high (fuel oil, river water, viscous oils).
Mesh size?
Commonly 40–100 mesh for fuel oil; confirm micron rating from the pump OEM.
