Procedure
- Select a suction line the same size as the pump suction port; suction line must be one size larger than the discharge line.
- Use a good grade of suction hose that will not collapse and is free of air leaks.
- Install the line strainer on the discharge side of centrifugal pumps in the line to the boom or spray gun.
- Mount the discharge port vertically at the top of the pump to eliminate air pockets.
- A relief valve or bypass line is not necessary and is not recommended.
Specs & values
- Example: if 3/4" discharge line, use 1" suction line.
