Selecting the Right Product

Tate Andale Guardian strainers and filters are designed to remove foreign matter from flowing liquids and gases. They should be selected according to the type of liquid and the degree of straining required.

Strainer and filter sizes should be selected on the basis of allowable pressure drop, not pipeline size. Suction service usually requires lower pressure drops than discharge service. When strainers and filters are used for high viscosity fluids, pressure drops will increase and larger units than normal may be required to keep pressure drops within reasonable limits.

The size of the strainer and filter should be a function of the job not the pipeline size. The pressure drop curves in this catalog are provided as a guideline for sizing and selection of the right product for your particular application.

Factors to Consider

Information required to properly select a strainer includes:

• Flow in GPM
• Working pressure
• Fluid temperature
• Type of fluid (other than water)
• Chemicals and oils
  • Temperature
  • Viscosity
  • Specific gravity
• Minimum particle size and maximum quantities of debris to be removed from fluid
• Maximum allowable clean pressure drop
• Materials compatible with fluid being strained
• Basic type of strainer or filter
