Parker Denison T6EC-052-022-1R11-B1 Hydraulic Pump – D-024-03359-0/11RO

Series-specific model code

Original model: T6EC-052-022-1R11-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.
052	Pump core 1 documented displacement: 164.8 cm3/rev.
022	Pump core 2 documented displacement: 70.3 cm3/rev.
1	T6EC shaft code: 1. Contact us to confirm.
R	Rotation: right-hand (clockwise), viewed from the shaft end.
11	Porting code: 11. 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.
