Parker Denison T7CS-E20-1R03-A1MW Hydraulic Pump – 054-90171-003S

Series-specific model code

Original model: T7CS-E20-1R03-A1MW

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

Evidence profile: T7CS series-first T-family profile (manual-evidence revision 7)

Code segment	Evidence-bound meaning
T7CS	Series code: T7CS.
E20	Pump core displacement code: E20. Contact us to confirm.
1	T7CS shaft code: 1. Contact us to confirm.
R	Rotation: right-hand (clockwise), viewed from the shaft end.
03	Porting code: 03. Contact us to confirm.
A	Design letter: A.
1	Seal code 1: BUNA N seal class.
MW	Remaining design, connection or modification selection: MW. 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.
