Which statement best describes a diaphragm pump’s typical use?

• A. Used in both low and high pressure applications of abrasive or corrosive chemicals
• B. Used only for low pressure
• C. Used only for irrigation water
• D. Used for seed coating spraying

Answer: (A)

Diaphragm pumps are versatile and built to handle a wide range of pressures as well as liquids that are abrasive or corrosive. The flexible diaphragm, driven by a rod or air, provides a tight seal and a pulsating flow that works well for gentle transfer at low pressure and for high-pressure spraying when needed. That combination makes them a common choice for moving and applying crop protection chemicals, fertilizers, and other harsh fluids in agriculture, where you may need both low-pressure transfer and high-pressure spraying, all while resisting chemical wear. They aren’t limited to irrigation water, and while seed coating spraying can use various pump types, the defining use of a diaphragm pump is its ability to operate across pressure ranges with abrasive or corrosive liquids.
