Series-specific model code

Original model: T6CCW-020-010-2R21-C110

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

Evidence profile: T6CCW exact single/double/triple ordering-code profile (HY29-0001/UK evidence revision 6)

Code segment	Evidence-bound meaning
T6CCW	Series: T6CCW. HY29 order-code variant of T6CC with severe-duty shaft option.
020	Shaft-end pump core (C family) displacement code: 020. Contact us to confirm.
010	Cover-end pump core (C family) displacement code: 010. Contact us to confirm.
2	Shaft code 2: keyed SAE BB shaft, severe-duty option.
R	Rotation: right-hand (clockwise), viewed from the shaft end.
21	Two-character porting code preserved; physical port orientation: 21. Contact us to confirm.
C	Design letter: C.
1	Seal code 1: S1 BUNA N seal class.
10	Connection/modification code: 10.

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.
