Current catalog differences: Several codes list decimal-resolved maxima versus published rounded values. Confirm the approved curve and stage count before quotation.
Published data lists other voltages and optional cable length. Single-phase 115 V is not a published QXN supply option.
Construction
Double shaft seals. Oil chamber cooling path.
Printed pages 78-79 place the hydraulic part under the motor so pumped water cools the motor when the set is only partially immersed.

SOURCE & REVIEW
Evidence stays tied to QXN.
Published source
Published data printed pages 78-83 with nomenclature, materials, outlet diagrams, separate 50/60 Hz tables, curves and dimensions.
Current catalog
Forty exact frequency records for thirty-seven codes. Six published 60 Hz codes currently lack catalog records.
Confirmation
Stage-count differences between 50/60 Hz naming, published-only 60 Hz codes and decimal-resolved maxima require confirmation.
QXN FAQ
Model boundaries and quotation checks.
Is QXN a separate Contents item?
Yes. QXN is an independent published data Contents item on printed pages 78-83, titled Submersible pump QXN.
Why are 50 Hz and 60 Hz model codes different?
Published performance tables list stage-count codes separately by frequency. Some 60 Hz rows use different impeller-stage numbering than the matching 50 Hz family, so both tables remain visible.
Which published 60 Hz codes lack current catalog records?
Printed 60 Hz rows without a current catalog match are QXN10/2-3, QXN12.5/2-4, QXN15/2-5.5, QXN40/2-15, QXN40/2-18.5, QXN40/3-22. Those hydraulic rows stay published-only and are not invented as current records.
How many current catalog records match?
The current catalog has forty frequency records covering thirty-seven exact codes that appear in the published 50 Hz or 60 Hz tables.
What construction does published data emphasize?
Printed pages 78-79 state the hydraulic part sits under the motor for water cooling when only partially immersed, with double shaft seals and an interposed oil chamber. Materials include cast-iron wet-end parts, stainless outer casing below 30 kW and Sic-Sic mechanical seal.
Need multi-stage well or industrial transfer?
