At full speed, what is the RPM for the P-6?

• A. 3900 RPMs
• B. 3000 RPMs
• C. 3600 RPMs
• D. 4200 RPMs

Answer: (A)

When you see “At full speed,” focus on the engine speed driving the pump. The P-6 is powered by a gasoline engine whose maximum governed speed is around 3900 RPM, and the pump’s performance (flow and pressure) is specified at that full-throttle speed. So 3900 RPMs represents the speed at which the pump is designed to operate to deliver its rated performance. Running at a lower speed, like 3600 or 3000, would reduce the pump’s discharge and pressure because the impeller and flow are tied to the engine RPM. Pushing above the engine’s safe limit, such as 4200, could over-speed and damage the unit.
