What term describes the latest generation priming pump system that is oil-less and air-driven?

• A. Pneumatic prime
• B. Oil less, pneumatic primer
• C. Prime Safe
• D. Electric primer

Answer: (B)

An oil-less, pneumatic primer is the priming system that uses compressed air to drive a piston or actuator, and it operates without any oil lubrication inside the primer. This combination means the pump can be primed quickly and cleanly, with less maintenance and no oil contamination risk in the water stream. The term explicitly communicates both main features: air-driven action (pneumatic) and oil-free construction (oil-less). Other terms fall short because one describes air-driven action without stating oil-free, another describes electric or non-air-powered priming, and a brand-style name isn’t the standard technical description.
