How to check the fit
Match the hydraulic duty
Compare pump capacity and the pressure adjustment range. Check the required loaded flow against the applicable performance curve; no-load flow alone is insufficient.
Match the motor and installation
Check motor output, actual supply voltage and frequency, terminal-box position, mounting and rotation against the existing unit.
