Hydraulics & Pneumatics

.Ist das alles die gleiche seite?

Hydraulic and pneumatic systems generate, control, and transmit power through pressurised fluid or compressed air, driving machinery across manufacturing, mobile equipment, and process industries. This category brings together suppliers of hydraulic and pneumatic components, complete presses, clamping and chucking devices, and pneumatic accessories and actuators.

    What this category covers

    Hydraulics and pneumatics cover two related but distinct power transmission technologies. Hydraulic equipment uses pressurised fluid to generate high forces in a compact package and includes components such as cylinders, pumps, motors, valves, and hoses, as well as complete machines such as hydraulic presses and hydraulic clamping or chucking systems for workholding and tool clamping. Pneumatic equipment uses compressed air for faster, lighter-force applications and includes actuators, pneumatically operated chucks, and accessories such as filters, regulators, lubricators, couplings, and air tools. Suppliers listed here range from component manufacturers and machine builders to distributors, system integrators, and service providers who design, assemble, or maintain hydraulic and pneumatic systems for manufacturing, mobile equipment, and process applications.

    How to shortlist Hydraulics & Pneumatics suppliers

    At the pre-selection stage, focus on which technology and component types a supplier actually specialises in, since hydraulic and pneumatic engineering require different design and sealing expertise. Check which industries and pressure or force ranges a supplier typically serves, and which safety and quality standards they design and test to; ISO 4413 covers safety requirements for hydraulic systems and ISO 4414 covers pneumatic systems, while ISO 8573 defines compressed air quality classes and ISO 9001 confirms a general quality management system. For equipment used in potentially explosive atmospheres, confirm compliance with the ATEX directive 2014/34/EU. Delivery reliability is consistently ranked by industrial buyers as the most important factor when choosing a new supplier, so weight demonstrated supply capability alongside technical fit.

    Frequently asked questions

    What is the difference between hydraulic and pneumatic equipment?
    Hydraulic systems use pressurised liquid to generate high, controllable forces in compact components, while pneumatic systems use compressed air for faster but generally lower-force motion. The choice depends on the required force, speed, precision, and environment.

    Which standards apply to hydraulic and pneumatic systems?
    ISO 4413 sets safety requirements for hydraulic systems and ISO 4414 for pneumatic systems. ISO 1219 defines the graphical and circuit symbols used in hydraulic and pneumatic diagrams, and ISO 6020 and ISO 6022 define mounting dimensions for hydraulic cylinders.

    What should I check before shortlisting a supplier for explosive-atmosphere applications?
    Confirm the supplier’s equipment is certified under the ATEX directive 2014/34/EU for the relevant equipment category and zone before including it in a shortlist for hazardous environments.
