Parker Denison T6EC-066-028-1R28-B1 Hydraulic Pump – D-024-31012-0/28RO

Series-specific model code

Original model: T6EC-066-028-1R28-B1

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

Evidence profile: T6EC series-first T-family profile (manual-evidence revision 7)

Code segment	Evidence-bound meaning
T6EC	Series code: T6EC.
066	Pump core 1 documented displacement: 213.3 cm3/rev.
028	Pump core 2 documented displacement: 88.8 cm3/rev.
1	T6EC shaft code: 1. Contact us to confirm.
R	Rotation: right-hand (clockwise), viewed from the shaft end.
28	Porting code: 28. Contact us to confirm.
B	Design letter: B.
1	Seal code 1: BUNA N seal class.

The source first segment is retained as the series code. Pump-core positions are recovered only when the shaft/rotation/porting boundary is structurally unambiguous; a documented family-local displacement table is then applied per core. An unknown series variant or option never prevents later independent fields from remaining visible.
