KS(M) · SUBMERSIBLE DRAINAGE PUMP
KS(M) drainage pump.
Compact abrasive-liquid duty.
Published data describes a compact design for abrasive liquid in general construction and civil engineering. Motor and pump bodies use rigid cast iron or stainless steel, with a high-pressure-resistant mechanical seal, semi-open high-chrome alloy impeller and ductile-iron wear plate, plus a discharge channel cast into the motor housing for cooling.

Series Overview
Key specifications shared across the KS(M) series.
Published applications include civil engineering, mines and quarries, sewage treatment plants and general pumping. Discharge covers 50-150 mm with motors from 0.25 to 15 kW. These are published statements, not external verification.
Model Range
Compare hydraulic performance across all available power ratings.
Printed pages 56-59 define KS(M) as SUBMERSIBLE DRAINAGE PUMP. KS is three phase, KSM is single phase, and an F suffix adds a float switch. Float codes are not separate counted rows below.

Published tables list separate 50 Hz and 60 Hz rows. Single-phase KSM rows use 220 V; three-phase KS rows use 400 V at 50 Hz and 380 V at 60 Hz. Trailing-F float rows share the same hydraulics with higher packing weight and are not counted separately.

Current catalog differences: KS31.5 currently lists 50 Hz only. Several codes show decimal-resolved maxima versus published rounded values, for example KS21.5 at 50 Hz lists 129.9 GPM versus published 132.1 GPM, and KS615 at 50 Hz lists 755.5 GPM versus published 739.7 GPM. Confirm the approved curve before quotation.
Published data lists other voltages and optional cable length. 60 Hz customizable where a published 60 Hz row exists; missing current 60 Hz rows are disclosed above rather than described as not available.
Construction
High-chrome impeller. Cast-iron and stainless stack.
Printed page 57 lists component materials by power band. 0.25-0.75 kW uses ductile-iron impeller and Sic-Ceramic/Ceramic-Carbon seal; 1.5-5.5 kW uses high-chrome alloy impeller with Sic-Sic seals by power.

SOURCE & REVIEW
Evidence stays tied to KS(M).
Published source
Published data printed pages 56-59 with KS(M) narrative, materials, dimensions, 50/60 Hz curves and twenty base performance codes.
Current catalog
Thirty-nine exact frequency records for twenty base codes, plus float-switch and catalog-only codes disclosed outside that count.
Confirmation
Decimal-resolved maxima, KS31.5 60 Hz availability, KS2.75 catalog-only status and float configuration scope require confirmation.
KS(M) FAQ
Model boundaries and quotation checks.
Is KS(M) a separate Contents item?
Yes. KS(M) is an independent published data Contents item on printed pages 56-59, titled SUBMERSIBLE DRAINAGE PUMP KS(M). KSE is a separate intelligent Contents item.
How are KS, KSM and F suffixes counted?
Published footnotes define KS as three phase, KSM as single phase, and an F suffix as float switch. This page counts twenty base hydraulic codes. Float-switch codes are configuration options and are not separate counted rows. Single-phase models can be configured with a float switch.
Which current records match those twenty codes?
The current catalog has thirty-nine frequency records for the twenty base codes. KS31.5 currently lists 50 Hz only. Matching trailing-F float codes remain outside that count.
What about KS2.75 in the current catalog?
KS2.75 appears as a current catalog-only code and is not a row in the published KS(M) performance table. Its product image path matches KSM2.75, so it is disclosed rather than treated as a published hydraulic selection.
Why do some current maxima differ from published data?
Published performance rows and current catalog records are separate sources. Several codes show decimal-resolved maximum flow or head values, so both remain visible without silently replacing one source.
