Series-specific model code

Original model: T6CC-B20-B12-1R19-C111

Code coverage: Evidence-supported meanings shown. Confirmation required for remaining configuration.

Evidence profile: T6CC exact single/double/triple ordering-code profile (HY29-0001/UK evidence revision 6)

Code segment	Evidence-bound meaning
T6CC	Series: T6CC.
B20	Shaft-end pump core (C family) documented displacement: 63.8 cm3/rev.

1	Shaft code 1: keyed non-SAE shaft.
R	Rotation: right-hand (clockwise), viewed from the shaft end.
19	Two-character porting code preserved; physical port orientation: 19. Contact us to confirm.
C	Design letter: C.
1	Seal code 1: S1 BUNA N seal class.
11	Connection/modification code: 11.

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.
