What pressure range can hydraulic sprayers produce?

• A. 50 to 300 psi (345 to 2068 kPa)
• B. 5 to 15 psi
• C. 10 to 20 psi
• D. 400 to 800 psi

Answer: (A)

Hydraulic sprayers rely on a pump to pressurize the liquid so it exits the nozzle as a spray with droplets of a usable size. That requires a moderate to high pressure, but not extremely high, to ensure proper atomization and good coverage without excessive drift. In ornamental pest management, the typical operating range is about 50 to 300 psi (roughly 345 to 2068 kPa). This range strikes a balance between effective spray breakup and control over where the spray goes. Pressures at the low end won’t atomize well, leading to poor coverage, while very high pressures (around 400 to 800 psi) tend to produce very fine droplets and greater drift, which isn’t standard for these sprayers.
