T strainer

T strainer

A plugged nozzle is one of the most frustrating problems that applicators experience with sprayers. Properly selected and positioned T strainer and screens will help prevent nozzle plugging and reduce nozzle wear.

T strainer numbers (e.g. 20-mesh, 50-mesh, or 100-mesh) indicate the number of openings per inch. T strainers with high numbers have smaller openings than T strainers with low numbers.

Coarse basket strainers (also commonly referred to as basket filters) set in the tank-filler opening prevent debris from entering the tank as it is being filled. A 16- or 20-mesh tank basket filter will also restrain lumps of wettable powder until they are broken up, helping to give uniform mixing in the tank.

The line T strainer is the most critical T strainer of the sprayer. It usually has a screen size of 16 to 80 mesh, and it can be positioned between the tank and the pump, between the pump and the pressure regulator, or close to the boom, depending upon the type of pump used. Roller and other positive displacement pumps should have a line T strainer (40- or 50-mesh) located ahead of the pump to remove material that would damage the pump. In contrast, the inlet of a centrifugal pump must not be restricted. A line T strainer (usually 50-mesh) should be located on the pressure side of the pump to protect the spray and agitation nozzles. Be sure to clean this screen regularly. http://www.3spipeline.com/T-strainers-Products-1.html
