I just bought a trash pump without the gas engine.

What RPM do I spin it at?

FWIW, I hate small gas engines. Nothing but trouble. I'll use a 3 phase
motor for this job.

Karl, I have repaired a ton of small engine powered pumps over the years,
3-8 HP, and I have ONLY seen engines running at 3600 RPM. No other RPM's,
just 3600.
Look for a electric motor running about 3450 it will work fine running
direct drive. No belts, no VFD needed. You will more than likely need to
build a mount and shaft setup to mimic the gas engine that would normally be
supplied with that pump.
