Hydraulic power pack with radial piston pump
These hydraulic power packs feature a hydraulic pump with pistons positioned radially around the central axis, forming a star-shaped structure.
This kind of setup allows high pressure levels and great reliability, making the power packs ideal for applications requiring considerable power and precision.
Typical applications
Hydraulic presses
For processing materials at high pressure.
Moulding and shaping machines
Mainly in the metal and plastics industry.
Testing systems
For testing components and materials under extreme loads.
Aerospace and automotive
Where precision and reliability are required.
Main features
Radial piston pump
Radial piston hydraulic pumps feature pistons that move radially to the central pump body. This design enables the pump to suck in and compress hydraulic fluid in order to generate very high pressures (700 bar and above).
High pressure
Hydraulic power packs with radial piston pumps are designed for applications where high pressure is essential. This makes them ideal for industries such as metalworking, where metal forming, shaping, and moulding machines require pressure of this kind.
High volumetric efficiency
Due to their optimised piston configuration, these power packs offer high volumetric efficiency, which minimises volume losses during the compression and release cycle. This results in greater energy efficiency and consistent performance even in harsh operating conditions.
Low noise
As radial piston pumps are well balanced, they tend to generate less vibration and noise than other pump types. This feature is particularly advantageous in industrial environments where noise levels must be kept low.
Durability and reliability
Thanks to their sturdy design and even load distribution across the pistons, these power packs offer a very long operating life. They are designed to withstand heavy loads and continuous operation without compromising performance.
Hydraulic vane pumps
Hydraulic vane pumps are particularly valued for their ability to provide a continuous flow of fluid, for their operational efficiency, and for their relatively simple construction.
Vane pumps are commonly used in manufacturing and in machine tools. They are a popular choice for many hydraulic applications due to their reliability, efficiency and ability to provide a constant flow.
Typical applications
Industrial machinery
Used to power hydraulic actuators, cylinders, and other motion control systems.
Principle of operation
1. Rotor rotation
The rotor, mounted eccentrically to the inner surface of the pump body, starts to rotate. The vanes, mounted on rotor grooves, are pushed outwards by centrifugal force or internal springs.
2. Increase and decrease of chambers
During rotation, the vanes form chambers between the rotor and the inner wall of the pump casing. These chambers increase in volume during suction and decrease during compression.
3. Fluid suction
When the chamber volume increases, hydraulic fluid is sucked into the pump through the inlet port.
4. Compression and discharge
As the rotor continues to move, the chamber volume decreases, compressing the fluid, which is then pushed through the pump’s outlet port.
Main features
Constant flow
Vane pumps are known to generate a stable fluid flow, making them suitable for applications requiring consistent accurate flow control.
High volumetric and energy efficiency
Thanks to the vane design that adapts to the shape of the rotor and chamber, these pumps maintain good volumetric efficiency. As they operate at moderate pressures while maintaining a continuous flow, they are also energy efficient.
Low noise
As operation is smoother with respect to other kinds of hydraulic pumps (such as gear pumps), vane pumps provide lower noise levels.
Reliability
Provided that the fluid is kept clean and the components well lubricated, vane pumps are reliable and long-lasting.
Compact design
Their minimalised footprint means they can be integrated into systems where space is limited.
