How to Build a Standard VFD Range for Your Water Pump Products

Build a standard VFD range by grouping pumps with compatible supply voltage, motor current, motor type and control needs. Use the fewest validated variants that safely cover the range; do not force one model or parameter file onto incompatible products.

What Information Is Required?

• Complete pump and motor matrix.
• Highest current at each nominal power.
• Induction and PMSM product groups.
• Supply and destination-market variants.
• Application, sensor and multi-pump functions.
• Annual volume and spare strategy.

Selection Example

For 2.2–11 kW booster pumps, map each nameplate current to a documented VFD output rating. Separate special-voltage and PMSM variants, then validate representative low, middle and high ratings before releasing the range.

Common Mistakes

• Using kW as the only grouping field.
• Creating too many cosmetic model variants.
• Mixing incompatible motor types.
• Ignoring environmental derating.
• Stocking spares without approved parameters.

AUSENIST Solution

AUSENIST can help construct a YS620/YS820 selection matrix, reduce unnecessary variants and prepare controlled parameter baselines. The final range is released only after representative pump testing.
