Hydraulics and pneumatics

Hydraulics and pneumatics for machinery and maintenance

Hydraulics uses a working liquid to transmit energy, while pneumatics most commonly uses compressed air. Both areas include supply, control and actuating components, but parts must be selected for the specific medium and installation conditions. In the NERON catalogue, you can move from a component group to a specific variant and compare the parameters needed when building, upgrading or servicing a machine.

Hydraulic pumps, motors and power packs

When choosing hydraulic pumps, hydraulic motors or hydraulic power packs and mini power packs, start with the full unit code and system documentation. Compare the required flow, pressure range, drive parameters, mounting and connections. When assembling a unit, also check hydraulic power pack components. An identical group name does not confirm compatibility between two different variants.

Control valves, cylinder parts and cylinder materials

Hydraulic flow dividers and directional control valves are selected according to the system function and schematic. When comparing versions, consider the control method, number and function of ports and the manufacturer's specifications. In the cylinder components section, look for parts that match the design of the particular assembly. Hydraulic rods and tubes require their dimensions, tolerances, material and surface finish to be compared with the technical drawing.

Hydraulic fittings, quick couplings and connections

Hydraulic fittings and adapters, quick couplings, SAE flange connections and rotary unions must be identified by the complete connection. Thread type and size, sealing surface geometry, design series and permissible operating parameters are important. A similar diameter of BSP and NPT threads does not mean compatibility. Even matching threads are insufficient if the components use different sealing methods.

Pneumatics and compressed air preparation

The pneumatics section leads to tubing and hoses, cylinders, valves and solenoid valves, push-in fittings, filters, regulators and air preparation units. When selecting tubing and a fitting, compare the diameter required by the connection system, material, medium and pressure and temperature range. Tubing and connection parameters must be considered together. For a cylinder, specify details including bore, stroke, operating principle and mounting; for a solenoid valve, also specify coil voltage and valve function.

Filtration and hydraulic seals

In the filtration technology section, compare the filter element designation, dimensions, filter operating location and filtration parameters specified in the documentation. Selecting seals requires the profile, dimensions and material to be identified, as well as the medium and operating conditions. A photo helps identify the shape but does not replace the full part specification.

What should an enquiry for hydraulic and pneumatic parts include?

• The full manufacturer's code and a photo of the plate or component marking.
• Medium type, pressure, temperature and required flow, where applicable to the component.
• Connection type, installation dimensions and sealing method.
• A schematic or technical drawing and the required number of pieces.
• Whether you need an identical part or are looking for a replacement whose compatibility must be confirmed.

Questions about selecting hydraulic and pneumatic components

Can a fitting be selected by thread diameter alone?

No. The thread type and pitch and sealing geometry are also needed. Compare the designations and drawings of both components being connected.

Can pneumatic tubing be selected solely by colour?

No. Selection depends on dimensions, material and compatibility with the medium, temperature and pressure. Colour does not confirm technical parameters.

How can I find a replacement pump or cylinder?

Start with the full designation and equipment documentation. Compare operating parameters and installation dimensions. Similar appearance does not confirm interchangeability.

Are all catalogue items available immediately?

Availability depends on the specific product and variant. Check the information on its product page and confirm the delivery time for an unusual component in your enquiry.
