SOURCE & REVIEW
Evidence stays tied to KSS(M).
Published source
Published data printed pages 64-67 with stainless narrative, applications, 50/60 Hz curves and sixteen base performance codes.
Current catalog
Thirty-one exact frequency records for sixteen base codes, plus float-switch codes disclosed outside that count.
Confirmation
KSS31.5 60 Hz availability, decimal-resolved maxima and float configuration scope require confirmation.
KSS(M) FAQ
Model boundaries and quotation checks.
Is KSS(M) a separate Contents item?
Yes. KSS(M) is an independent published data Contents item on printed pages 64-67 for the stainless submersible drainage pump.
How are KSS, KSSM and F suffixes counted?
Published footnotes define KSS as three phase, KSSM as single phase, and an F suffix as float switch. This page counts sixteen base hydraulic codes. Float-switch codes are configuration options and are not separate counted rows.
Which current records match those sixteen codes?
The current catalog has thirty-one frequency records for the sixteen base codes. KSS31.5 currently lists 50 Hz only. Matching trailing-F float codes remain outside that count.
What materials does published data emphasize?
Printed page 64 states stainless steel construction for the motor and pump body for corrosion resistance, with applications including corrosive liquids, civil engineering, mining and sewage treatment.
Why do some current maxima differ from published data?
Published performance rows and current catalog records are separate sources. Several codes show decimal-resolved maxima, so both remain visible without silently replacing one source.
Need stainless drainage for corrosive liquids?
