ATOS hydraulic pumps: high performance, low noise levels, and maximum reliability

In the design of high-performance hydraulic systems, the choice of pump is a key factor that determines efficiency, maintenance requirements, and the overall service life of the system.

At Stern Hidráulica, as official distributors of ATOS, we integrate vane pumps, axial piston pumps, and high-quality multiple pump combinations into our systems, tailored to each industrial application.

PFE Vane Pumps: robust simplicity and long service life
PFE fixed-displacement vane pumps stand out for their reliability, operational efficiency, and ease of maintenance. They are particularly well suited for industrial applications requiring quiet and continuous operation, with more than one million cycles guaranteed.
Key features:

• Quiet and long-lasting operation
• Compatible with hydraulic oils and synthetic fluids
• Simple and accessible maintenance ATEX certification available on request

PVPC Axial Piston Pumps: precision under pressure
PVPC variable-displacement axial piston pumps are designed for high-pressure applications (up to 350 bar) that require precise flow control and low noise emissions.

Key advantages:

• Four base models with displacements of up to 90 cm³/rev
• Hydraulic and electro-hydraulic servo controls available
• Hydraulic balancing of the rotating group and pistons
• 9-piston design to reduce pulsation and noise
• ATEX certification available on request

Multiple Pumps: intelligent modularity
Thanks to their modular “meccano-type” design, ATOS pumps allow vane and piston pumps to be combined on a single drive shaft, offering maximum versatility and adaptability for complex hydraulic power units.

This flexibility makes it possible to align flow characteristics, pressure levels, and mechanical configuration with the specific requirements of each hydraulic system.

At Stern Hidráulica, we design and integrate complete hydraulic solutions with ATOS components, delivering reliability, energy efficiency, and precise control for sectors such as industrial machinery, energy, mining, recycling, and defense.Is this conversation helpful so far?
