The pump impeller generates RPM within which range?

Explanation:
The speed of the pump impeller is set by the motor driving it, so in typical pump systems you see only a few thousand RPM. For a standard AC motor (60 Hz), a common 2-pole design runs around 3600 rpm, and the actual impeller speed is a bit lower due to slip—often about 3000–3500 rpm. That places the usual impeller speed squarely in the 2000–4000 rpm range. Speeds much outside this range are not typical for ordinary pumps: very low speeds would require special arrangements, while very high speeds belong to specialized high-speed pumps.
