This is a mirror. The citable record is on Zenodo: https://doi.org/10.5281/zenodo.22920668 (the concept DOI for all versions is https://doi.org/10.5281/zenodo.22920667). The five data files here are byte-identical to that deposit; their MD5 values are listed below and match the values Zenodo reports. Newer versions are released on Zenodo first.

What this is

Item numbering on ANSI/ASME B73.1 horizontal end-suction process pumps is used constantly and written down in machine-readable form almost nowhere. A maintenance planner reading a sectional drawing has to move between three things: an item number, the part it identifies, and the frame or group that part belongs to. This dataset states that mapping for one manufacturer's products so it can be cited, checked and corrected.

It covers two series:

• G196 series, built to the published Goulds 3196 dimensional pattern and organised by frame (STX, MTX, LTX, XLTX).
• D Mark III series, built to the published Durco Mark III dimensional pattern and organised by group (1, 2, 3).

Method

Every value in Tables 1, 2 and 4 was extracted programmatically from tables already published on the manufacturer's own website on 2026-09-22, not transcribed from drawings or scanned documents. The extraction reads the published HTML tables and normalises the size-designation separator to x. Because the dataset is generated from those pages rather than retyped, it cannot silently drift from them.

The sectional callout table (Table 3) is the exception: those item numbers were read off the manufacturer's own sectional drawings by a person, sheet by sheet. They are reported per sheet rather than merged, because the sheets are not supersets of one another: item 319 appears on the STX and MTX sheets but not on XLT-X, and 360A only on XLT-X. The drawing labels that frame XLT-X while the manufacturer's prose calls it XLTX; the sheet labels here follow the drawing.

Field definitions

Field	Meaning
series	G196 or D Mark III, the manufacturer's own series name
pattern	The published dimensional pattern the series is built to
item_no	Item number (G196) or POS number (D Mark III) used for that part on a sectional drawing
part	What the item number identifies
ysm_ref_suffix	The manufacturer's own reference suffix for that part
materials	Material options offered for that part
confirmed_before_order	What must be confirmed from the nameplate or drawing before that part is ordered
family	The frame (STX, MTX, LTX, XLTX) or group (1, 2, 3) a set of sizes belongs to
sizes	Size designations that family covers, as discharge x suction - nominal impeller diameter
sheet	Which sectional sheet a callout appears on
pump_size	A size designation
casing_ysm_ref, impeller_ysm_ref	The manufacturer's references for the casing and impeller of that size

Limitations and scope

• No OEM part numbers are included. Item numbers here are the standard item and POS numbering used on B73.1 sectional drawings; the reference suffixes are this manufacturer's own.
• Goulds, 3196, Durco and Mark III are trademarks of their respective owners. They are named only to identify the published dimensional pattern a series is built to. YSM Pumps is an independent manufacturer, not affiliated with, sponsored by or endorsed by ITT Goulds Pumps or Flowserve.
• Interchange applies to a pump of the same size designation and frame or group, confirmed against the nameplate and the installed pump drawing. Nothing in this dataset states that a part will fit a specific installed pump.
• Values are catalogue ranges for screening and identification, not guarantees for every size and configuration. A quotation is confirmed against size-specific reviewed documents.
• This dataset describes one manufacturer's products. It is not a survey of the industry and should not be read as one.
