SOURCE & REVIEW

Evidence stays tied to SH-W.

01

Published source

Published data printed pages 75-77 with double-impeller narrative, materials, dimensions, curves and nine performance rows.

02

Current catalog

Eighteen exact frequency records for the nine trailing-W codes under series SH.

03

Confirmation

SH23.0W dimension OCR gaps on A/B/n-Ød and decimal-resolved current maxima require confirmation.

SH-W FAQ

Model boundaries and quotation checks.

Is SH-W a separate Contents item from SH?

Yes. SH-W is an independent published data Contents item on printed pages 75-77. SH without the trailing W is a separate Contents item on printed pages 72-74.

What does the W suffix mean here?

Published SH-W copy states a back-to-back double-impeller design that reduces axial force and improves bearing life. Do not infer that meaning for other families.

How are SH-W codes filtered in the current catalog?

Current catalog series SH contains both families. This page counts only the nine trailing-W published codes and eighteen matching frequency records.

Are 50 Hz and 60 Hz both published?

Yes. Printed page 77 lists 50/60 Hz performance for all nine codes. Current catalog also lists both frequencies for each code.

What materials does published data list?

Printed page 76 lists two high-chrome alloy impellers, ductile-iron diffuser and casing parts, cast-iron motor body parts, AISI 420 SS shaft and a stainless-steel strainer.
