Series-specific model code

Original model: T7DB-B28-B15-5R00-A1M0

Code coverage: Evidence-supported selected code meanings identified.

Evidence profile: T7DB exact single/double/triple ordering-code profile (HY29-0001/UK evidence revision 6)

Code segment	Evidence-bound meaning
T7DB	Series: T7DB.
B28	Shaft-end pump core (D family) documented displacement: 90.0 cm3/rev.
B15	Cover-end pump core (B family) documented displacement: 50.0 cm3/rev.
5	Shaft code 5: keyed ISO 3019-2 G32M shaft.
R	Rotation: right-hand (clockwise), viewed from the shaft end.
00	Porting code: 00 (standard porting).
A	Design letter: A.
1	Seal code 1: S1 BUNA N seal class.
M0	Connection/modification code: M0.

The exact longest series prefix determines the number and family of pump-core slots. Displacement codes are decoded only through the family table printed for that slot; identical codes are not generalized across A-AS, A-ASW, B, C, D or E cores. Shaft identity remains tied to the complete series. R/L is interpreted from the shaft-end view. Porting 00 is standard; other catalog-shaped porting codes are retained and require physical-orientation confirmation. Unsupported families and unknown special tails fail closed without blocking earlier evidence-supported fields.
