Current catalog differences: Several codes list maximum head even though the published table does not; KA1211 / KA1215 current outlet is listed as 320 mm while published dimensions use 300 mm / 315 (DN300); maxima such as KA85.5 and KA107.5 show decimal-resolved or different values versus published rounded capacity. Confirm the approved curve and connection before quotation.

SOURCE & REVIEW

Evidence stays tied to KA.

01

Published source

Published data printed pages 68-71 with seawater narrative, materials for both power bands, dimensions, curves and seven performance rows.

02

Current catalog

Fifteen exact frequency records for eight codes including KA4.75 and KAM4.75.

03

Confirmation

Outlet DN differences, current maximum-head fields and decimal-resolved maxima require confirmation.

KA FAQ

Model boundaries and quotation checks.

Is KA a separate Contents item?

Yes. KA is an independent published data Contents item on printed pages 68-71, titled Large flow seawater pump KA.

How are KA and KAM counted?

Published footnotes define KA as three phase and KAM as single phase. The published performance table shows seven hydraulic rows, with KA(M)4.75 covering both single-phase and three-phase 0.75 kW codes. KA1215 is published as 60 Hz only.

Which current records match?

The current catalog has fifteen frequency records covering KA4.75, KAM4.75, KA61.5, KA62.2, KA85.5, KA107.5, KA1211 and KA1215. KA1215 currently lists 60 Hz only, matching the published note.

What materials does published data list for seawater service?

Printed pages 70-71 list AISI 444 SS impeller, AISI 316L SS motor casing and rotor shaft, AISI 304 SS outer casing and strainer, PVC discharge connection and an aluminum-alloy cathodic protection plate.

Does the published KA table list maximum head?

No. The published performance table lists rated head and maximum capacity, not a separate maximum-head column. Current catalog records may list maximum head as a separate current-catalog fact.

Need low-head large-flow seawater or freshwater transfer?

Review KA performance rows and the current catalog codes.
