Compare pump capacity and the pressure adjustment range. Check the required loaded flow against the applicable performance curve; no-load flow alone is insufficient.
Check motor output, actual supply voltage and frequency, terminal-box position, mounting and rotation against the existing unit.
Manufacturer catalog and model-code reference. Confirm the supplied unit against its nameplate and the applicable manual.
