The pump is running. Is commissioning complete?
Pressure, flow, motor current, temperature and vibration recorded at startup provide a baseline for future maintenance and performance checks.

Why does a pump’s duty point change?
Tank levels, valve positions and pipe losses alter system resistance. Pump selection needs to account for the full operating range.
