Piston pumps are used for which conditions?

• A. High pressure applications or when using both high and low pressures (VRA-equipped sprayer)
• B. Low pressure only
• C. Aerial spraying
• D. Soil injection

Answer: (A)

Piston pumps are used when high pressure or changing pressure is needed in the spray system. They’re positive-displacement devices, delivering a fixed amount of fluid with each stroke, which lets them build and sustain high pressures even as the system feeds multiple nozzles or long hose runs. This makes them ideal for high-pressure spraying and for equipment that must switch between high and low pressures—such as a variable-rate application (VRA) sprayer where different zones require different pressures. Other pumps tend to excel at lower pressure or at steady, single-pressure operation, so they aren’t as well suited to applications that demand both high pressure and rapid pressure adjustments across a system.
