QNS · SUBMERSIBLE SAND PUMP
QNS sand pump.
4-pole duty with agitator.
Published data describes QNS as a submersible sand pump for harsh sites with solids and abrasive material. Each selection uses an F-class insulated 4-pole motor, high wear-resistant mechanical seal and heavy-duty semi-open high wear-resistant alloy impeller. An agitator at the lower part stirs bottom sediment into suspension for discharge.

SOURCE & REVIEW
Evidence stays tied to QNS.
Published source
Published data printed pages 50-52 with QNS narrative, summary specifications, applications, materials, R/Y installation, packing weights, 50/60 Hz curves and seventeen performance rows.
Current catalog
Thirty-four exact frequency records for seventeen published model codes, twenty-two catalog product image paths (eleven content-distinct after byte dedupe) and thirty-four dimension drawing paths (eighteen content-distinct) for those codes. Three further current codes sit outside the published performance table.
Confirmation
Current decimal, rated-point and voltage differences, approved performance curve, QNS-G body scope and final quotation scope require confirmation.
QNS FAQ
Model boundaries, materials and quotation checks.
Is QNS a separate Contents item?
Yes. QNS is an independent published data Contents item on printed pages 50-52, titled SUBMERSIBLE SLURRY PUMP QNS and described as a submersible sand pump. This page keeps its seventeen published model codes separate from adjacent Contents entries such as NTZ and KC.
Which QNS codes are currently listed?
The current catalog has thirty-four frequency records covering all seventeen published codes, with one 50 Hz and one 60 Hz record for each code. Three additional current catalog codes—200QNS430, 200QNS437 and 200QNS445—are not rows in the published performance table on printed page 51.
Why do some current maxima differ from published data?
Published performance rows and current catalog records are separate sources. Several codes show decimal-resolved or different maximum flow/head values, and some rated points differ, so both remain visible without silently replacing one source.
What wear parts does published data list for sand service?
Printed page 50 lists high-chrome alloy for the impeller, agitator and one inlet plate, with a cast-iron alternate inlet plate, ductile-iron pump body for QNS, and high-chrome alloy pump body for QNS-G. Mechanical seal is listed as Sic-Sic/Sic-Sic; shaft is AISI 420 SS.
Does QNS 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.
Need abrasive sand or slurry drainage with agitator assist?
