For booms up to 10 feet, a 4.0 GPM pump is ideal. Larger booms may require 5.5 GPM or higher.
Choosing the right flow ensures even application and avoids pressure drops.
GPM Guidelines:
- 5–10 ft booms: 4.0 GPM
- 12–15 ft booms: 5.5 GPM or more
- PSI regulators help fine-tune flow
Summary:
Match your sprayer pump’s GPM to your boom width for even coverage and reliable flow.
