Parker Denison T6EC-057-012-1R00-B1-M536055 Hydraulic Pump – 054-36055-000S

Series-specific model code

Original model: T6EC-057-012-1R00-B1-M536055

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.
057	Pump core 1 documented displacement: 183.3 cm3/rev.
012	Pump core 2 documented displacement: 37.1 cm3/rev.
1	T6EC shaft code: 1. Contact us to confirm.
R	Rotation: right-hand (clockwise), viewed from the shaft end.
00	Porting code: 00 (standard porting).
B	Design letter: B.
1	Seal code 1: BUNA N seal class.
M536055	Control, connection, design or special trailing selection: M536055. Contact us to confirm.

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.
