Basket strainer

The basket strainer is used for oil or other liquid pipelines to strainer the debris in the pipeline, and the strainer hole area is 2-3 times larger than the diameter pipe area. Far more than Y type, T type strainer area. The strainer structure is different from other strainer, because the shape is like a basket, so the name basket strainer.

The basket strainer is mainly composed of nozzle, barrel, strainer basket, flange, flange cover and fastener. Installed on the pipeline can remove large solid impurities in the fluid, so that the machine equipment (including compressors, pumps, etc.), instruments can work and operate normally, to stabilize the process and ensure the role of safe production.

Basket strainer is a small device to remove a small amount of solid particles in the liquid, which can protect the normal work of compressors, pumps, meters and other, when the fluid enters the filter bucket with a certain specification of the filter screen, its impurities are blocked, and the clean filtrate is discharged by the filter outlet, when it needs to be cleaned, as long as the detachable filter bucket is removed, and the process is re-loaded, so, Easy to use and maintain. It has been widely used in petroleum, chemical, pharmaceutical, food, environmental protection and other industries. If it is installed in series at the pump inlet or other parts of the system pipeline, it can extend the service life of the pump and other equipment, and ensure the safety of the entire syste.
