Hydraulic hose SEMPERIT DN50 2SN 2" 90 bar – double steel braid

Hydraulic hose SEMPERIT DN50 2SN is a rubber hose designed for transmitting hydraulic oil in power hydraulic systems. Internal diameter is 50 mm (2"), and the maximum working pressure is 90 bar. The hose construction is reinforced by two steel braids, ensuring adaptation for work in pressure installations. The hose is made using NBR rubber, and its operating temperature range is from -40°C to +100°C, momentarily up to +120°C. The product is intended for making complete hydraulic assemblies by crimping appropriately selected fittings on a hydraulic press.

Application and technical characteristics

SEMPERIT DN50 2SN is used in hydraulic installations requiring a hose with a large internal diameter. Size DN50 corresponds to a diameter of 2", allowing the selection of a hose for circuits where ensuring proper oil flow is essential. When designing the installation, the required flow rate, flow velocity, and pressure losses should be taken into account.

The hose has a 2SN type construction, meaning reinforcement consisting of two steel wire braids. The maximum working pressure for the offered DN50 diameter is 90 bar. This is a parameter for this specific hose and should not be identified with the working pressures of other 2SN hose diameters.

The product specification indicates NBR rubber and an operating temperature range from -40°C to +100°C, with the possibility of momentary temperatures up to +120°C. The hose has a black outer surface. When selecting a hose for an installation, the simultaneous influence of pressure, temperature, type of medium, and installation conditions must be considered.

The hose is adapted for mounting hydraulic fittings by crimping on a press. To create a complete assembly, fittings, crimp ferrules, and crimping parameters compatible with the hose construction must be selected. The working pressure of the finished assembly must not exceed the allowable pressure of its weakest component.

Why choose the SEMPERIT DN50 2SN hose?

Internal diameter DN50 – 50 mm (2").
Maximum working pressure 90 bar.
Double steel wire braid reinforcing the hose construction.
Operating temperature range from -40°C to +100°C, momentarily up to +120°C.
NBR material indicated in the product specification.
Possibility of crimping fittings to create a finished hydraulic hose assembly.

Frequently Asked Questions (FAQ)

What is the working pressure of the SEMPERIT DN50 2SN hose?

The maximum working pressure of the hose is 90 bar. This value is provided for the offered DN50 size. When assembling a complete hose, the allowable pressure of the fittings and crimp ferrules must also be taken into account.

What does the DN50 2SN designation mean?

DN50 means the nominal internal diameter of the hose is 50 mm (2"). The 2SN symbol defines the hose construction reinforced with two steel wire braids.

In what temperature range can the SEMPERIT DN50 hose operate?

According to the product sheet, the operating temperature range is from -40°C to +100°C. A momentary temperature up to +120°C is also allowed. The momentary value does not mean the possibility of continuous operation at such a temperature.

Can the SEMPERIT DN50 2SN hose be crimped?

Yes. The hose is designed for crimping fittings using a hydraulic press. Compatible ferrules and fittings should be selected, and crimping parameters provided for the given set of elements should be applied.
