How to check the fit

  1. 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.

  2. Match the motor and installation

    Check motor output, actual supply voltage and frequency, terminal-box position, mounting and rotation against the existing unit.
