Current catalog differences: NTZ33.7 lists maximum flow of 386.1 GPM versus published 380.4 GPM; NTZ411 lists maximum head of 88.3 ft versus published 88.6 ft. NTZ611 currently has no 60 Hz catalog record; 60 Hz is customizable for that code. Confirm the approved curve before quotation.
Published data also lists other voltages and optional cable length. Those options are not inferred into current records.

SOURCE & REVIEW
Evidence stays tied to NTZ.
Published source
Published data printed pages 47-49 with NTZ narrative, summary specifications, applications, materials, dimensions, 50/60 Hz curves and six performance rows.
Current catalog
Eleven exact frequency records for six current model codes, five content-distinct product image paths and six dimension drawings. One series image is shared by NTZ32.2 and NTZ33.7. NTZ611 has no current 60 Hz record listed.
Confirmation
Current decimal differences, NTZ611 60 Hz customization scope, approved performance curve and final quotation scope require confirmation.
NTZ FAQ
Model boundaries, cooling jacket and quotation checks.
Is NTZ a separate Contents item?
Yes. NTZ is an independent published data Contents item on printed pages 47-49. This page keeps its six published model codes separate from adjacent Contents entries such as KBS and QNS.
Which NTZ codes are currently listed?
The current catalog has eleven records for all six published codes. NTZ611 currently lists a 50 Hz record only; 60 Hz is customizable for that code.
What low-water feature does published data claim?
Published data states that a cooling water jacket allows the pump to operate at low water level for an extended period without fear of overheating. That is a published statement, not external verification.
Why can current maxima differ from published data?
Published performance rows and current catalog records are separate sources. NTZ33.7 and NTZ411 show decimal differences between the two sources, so both remain visible.
Does NTZ publish float or single-phase rows?
No. Published data and current catalog records for this family are three-phase only. Float switch and single-phase configurations are not listed as separate counted rows.
