Eaton Series 7 — hydraulic pumps
Eaton Series 7 is a line of medium-duty axial piston hydraulic pumps with displacements ranging from 45 to 124 cm³. The pumps are designed for open-circuit operation at pressures up to 240 bar and are used in mobile and industrial equipment requiring precise flow and pressure control. Depending on the configuration, the series includes models with pressure compensators, pressure-flow compensators (load sensing), and servo-controlled displacement.
Eaton Series 7 models
The series covers pumps with displacements from 45 to 124 cm³ in several design configurations.
All series are available in the Eaton hydraulics section.
Advantages
- Wide pressure range — up to 210 bar continuous and up to 240 bar peak, ensuring reliable operation under demanding conditions
- Flexible compensation — the choice between pressure and pressure-flow compensators allows precise matching of the pump to system requirements
- Auxiliary drive option (SAE A) on models 70523/70553 for powering additional consumers
- Interchangeable repair kits between 7620 and 7621 simplify fleet maintenance
Applications
