Hydraulic hose SEMPERIT 4SH DN50 2" 250 bar – four-spiral

The SEMPERIT 4SH DN50 hydraulic hose is a high-pressure rubber hose designed for transport of oil in hydraulic power systems. It has an internal diameter of DN50 (2") and a maximum working pressure of 250 bar. The hose construction utilizes four spiral layers of steel wire, providing reinforcement adapted to high pressure loads. The hose is equipped with an oil-resistant inner layer of synthetic rubber and an outer cover resistant to abrasion, ozone, and the influence of atmospheric factors. The operating temperature range is from -40°C to +100°C, intermittently up to +120°C. The hose is offered by the running meter and can be used for manufacturing crimped hydraulic hose assemblies.

Application and technical characteristics

SEMPERIT DN50 4SH is used in high-pressure hydraulic installations requiring hoses with a large internal diameter. It can be used in appropriately selected systems of industrial machines, construction machinery, and heavy hydraulic equipment. When selecting the hose, working pressure, oil temperature, required flow, and installation conditions should be considered.

The nominal diameter DN50 corresponds to the 2" size. The large internal cross-section allows for selecting the hose for circuits with a significant oil flow rate. Proper diameter selection should take into account the flow velocity, hose length, and permissible pressure losses. The DN50 size itself does not determine the maximum flow possible for a specific installation.

The 4SH construction utilizes four spirally laid layers of steel wire. Unlike 1SN and 2SN hoses, which have braided reinforcement, the 4SH hose uses spiral reinforcement. This structure is designed to carry high pressure loads. The maximum working pressure of the offered SEMPERIT DN50 model is 250 bar.

The inner layer is made of oil-resistant synthetic rubber. Its task is to ensure contact with the transported hydraulic medium. The outer layer of synthetic rubber protects the hose from abrasion, the effects of ozone, and atmospheric conditions. In the product parameters, NBR rubber is indicated as the material, and the outer color is specified as black.

The hose is designed for operation at temperatures from -40°C to +100°C. The product data sheet also allows for a short-term temperature increase up to +120°C. The temporary value does not imply the possibility of continuous operation at such a temperature. When selecting the hose, the simultaneous influence of temperature, pressure, and the properties of the transported oil must be considered.

Manufacturing hydraulic hoses and selecting fittings

The SEMPERIT 4SH DN50 hose can be used to manufacture a complete hydraulic hose assembly by mounting appropriately selected fittings and ferrules. Due to the four-spiral reinforcement, components compatible with the 4SH construction must be used. Crimping parameters, including hose end preparation and crimp diameter, should result from the technical documentation of the specific assembly kit.

When designing the hose routing, the minimum bending radius provided by the manufacturer should be maintained, twisting the hose around its own axis should be avoided, and areas exposed to intense friction should be protected. Particular attention should be paid to the appropriate support and routing of large-diameter hoses, especially in moving parts of machines.

The allowable working pressure of the finished hydraulic hose assembly is determined by the component with the lowest pressure rating. The 250 bar pressure applies to the hose itself and does not automatically mean that every used fitting or connector can operate at an identical load. Before starting the installation, the compatibility of all components must be checked.

Frequently Asked Questions (FAQ)

What working pressure does the SEMPERIT 4SH DN50 hose have?

The maximum working pressure of the hose is 250 bar. When making a complete hose assembly, the allowable pressure of the used fittings and other hydraulic components should also be checked.

What is the difference between 4SH and 2SN construction?

The 4SH hose has four spiral reinforcement layers of steel wire, while the 2SN hose uses two steel braids. Structural differences affect the properties and the way the hose is selected for specific operating conditions.

Is SEMPERIT DN50 4SH sold by the meter?

Yes. The unit of sale is the running meter. The hose can be prepared in sections of a length corresponding to the requirements of the hydraulic assembly being made.

Can fittings be crimped on the SEMPERIT 4SH DN50 hose?

Yes. Fittings are mounted on a hydraulic press using appropriately selected crimp ferrules. Due to the 4SH construction, recommendations regarding the selection of components and crimping parameters must be followed.

At what temperatures can the SEMPERIT DN50 4SH hose operate?

The product data sheet specifies the operating temperature range from -40°C to +100°C, with an allowable intermittent temperature up to +120°C. When selecting, the properties of the transported medium and operating conditions should be taken into account.
