04. Pumps

Description
The Atos SSP servo-pumps represent a significant advance in the generation and control of hydraulic power, combining the intrinsic advantages of fluid power with the ease of control and regulation of an electric drive. They guarantee high power density, superior dynamics and precision, significant reductions in energy consumption and noise levels, and outstanding reliability and structural robustness.
Atos is also a market-leading supplier of a comprehensive range of fixed and variable displacement pumps and multiple pump assemblies.
Pump Types
- Fixed displacement pumps: vane pumps, radial piston pumps and manually actuated pumps for medium/high pressures.
- Variable displacement pumps: axial piston pumps for high pressures with flow, pressure, load-sensing, constant power or P/Q controls with electronic maximum power limitation.
- Multiple pumps: modular assemblies combining fixed or variable displacement pumps for flexible hydraulic power management.
- Accessories: pressure transducers, electrical connectors and auxiliary components for servo-pumps.

06. Filters

Description
Fluid cleanliness is a primary consideration in the design of all hydraulic systems, as approximately 80% of failures are caused by solid contamination. While solid contamination cannot be completely eliminated, it can be continuously reduced and controlled through the use of hydraulic filters. Atos filters guarantee an optimised filtration system that maintains adequate fluid cleanliness, reducing contamination-related damage, extending machine service life and preventing unplanned production downtime.
Product Lines
- In-Line Filters
High-pressure filters with threaded or flanged ports for pressure lines. High-efficiency microfibre filter elements, with or without bypass. Differential clogging indicators — electrical or visual. Filtration rating: F03 ÷ F20
- Return Filters
Tank-mounted filters with threaded ports for return lines. High-efficiency microfibre or cellulose filter elements with bypass. Electrical or visual clogging indicators. Filtration rating: microfibre F06 ÷ F25 / cellulose C10 ÷ C25
- Suction Filters
Filters with threaded ports for direct mounting on the pump suction line. Wire mesh filter element, with or without bypass. Filtration rating: W125
