Suction hoses for fuel, gasoline, oil

Suction and delivery hoses reinforced with internal wire. 

Reinforced suction hoses for petroleum products 

Inner layer: NBR rubber, anti-electrostatic, oil-resistant. Reinforcement: 2 textile braids, steel wire spiral, copper wire for static discharge. Outer layer: NBR rubber, resistant to oil and gasoline, seawater, ozone, and weather conditions. Temperature range: -35°C to +80°C. Materials: Hoses are produced from durable materials such as synthetic rubbers resistant to petroleum substances. In some models, additional reinforcing layers are used, e.g., a steel spiral wire that provides resistance to vacuum and crushing. Reinforcements: The design is based on a special internal spiral wire, which guarantees high mechanical strength and flexibility. Temperature range: Hoses designed for handling fuels and oils can operate in a wide range of temperatures, usually from -30°C to +80°C, which allows their use in various environmental conditions. Chemical resistance: These hoses are designed with resistance to chemicals in mind, including gasoline, heating oils, crude oil, and their derivatives. Working pressure: Depending on the model, hoses are characterized by different maximum working pressures, allowing the selection of the right product for specific installation requirements.

Where are suction and delivery hoses used? 

Application: suction-delivery hose for petroleum products with aromatic compound content up to 50%, wide spectrum of applications in the automotive, marine industry, and industrial machinery. Most commonly, this type of hose is used in construction machinery: excavators, bulldozers, and delivers hydraulic oil to the hydraulic pump. Mounting is most often done using GBS hose clamps. Delivery and suction-delivery hoses are used in many industries, including: Fuel handling: At gas stations, transshipment terminals, and transmission systems. Transport: In refueling and distribution systems for fuels and oils in tankers and tanks. Petrochemical industry: For the transfer of flammable liquids in chemical plants and refineries. Agriculture: Used in fuel and oil transshipment systems in agricultural machinery. Ports and shipping: These hoses are also used for fuel transfer on ships and in seaports.

Oil hoses according to SAE 100R4 standard

The SAE 100R4 standard applies to low-pressure hydraulic hoses used mainly in return systems of hydraulic oil and in suction lines. Hoses meeting this standard are characterized by a durable construction and are used in applications where resistance to oils is required, as well as flexibility at low pressures. SAE 100R4 specifies minimum requirements for hose construction, working pressure, and resistance to environmental conditions such as abrasion and chemical action. These hoses are often used in power hydraulics systems, but also in other installations where low-pressure lines are needed. Suction-delivery hose for fuel TM 30 SEMPERIT

Suction hose 

A suction hose is a special type of technical hose designed for suctioning liquids, air, or other media under negative pressure (vacuum). Unlike ordinary delivery hoses, which work at positive pressure (pushing the medium), a suction hose must be resistant to crushing and wall collapse, which is why it often has spiral reinforcement made of steel wire or plastic. Characteristic features of a suction hose: Construction: inner layer resistant to the medium (e.g., water, oil, fuel), outer layer resistant to abrasion and weather conditions, spiral reinforcement. Vacuum resistance: the hose does not collapse even under strong suction. Flexibility: ease of laying the hose, even in limited spaces. Diameters: available in a wide range, e.g., from 19 mm (¾ inch) to over 200 mm.

SAE 100 R4 Hoses 

SAE 100 R4 is a standard of the American organization SAE (Society of Automotive Engineers), which specifies technical requirements for hydraulic hoses suction-delivery. This standard refers to hoses intended primarily for work on the suction side of the hydraulic system, where vacuum occurs, but also allows limited work on the delivery side. The SAE 100 R4 standard defines the construction of the hose, its strength parameters, and the range of applications. Hoses of this type have an internal rubber layer resistant to hydraulic oils, textile reinforcement, and a wire or plastic spiral designed to protect the line from collapsing during medium suction. The external rubber layer protects the hose from mechanical and environmental factors.

Application of SAE 100 R4 suction hoses 

SAE 100 R4 primarily refers to suction applications, such as suction of hydraulic oil, fuel, oil emulsions, or other working fluids. This standard is not intended for high-pressure operating systems, which is why R4 hoses are characterized by low working pressure compared to SAE 100 R1 or R2 hoses. Their main function is to ensure a stable flow of medium without the risk of suction and deformation of the line. In practice, hoses compliant with the SAE 100 R4 standard are used in power hydraulics as suction lines for hydraulic pumps, in hydraulic units, agricultural and construction machinery, and in industrial installations. The SAE 100 R4 standard constitutes a reference point for manufacturers and users, clearly defining what type of work a given hose is intended for and what requirements it must meet to ensure safe and stable operation.

Wire-reinforced hose for fuels and oils

Reinforced hose wire-reinforced is a professional suction-delivery hose designed to work with fuel, diesel, gasoline, and hydraulic oils in demanding industrial conditions. Thanks to the spiral steel reinforcement embedded in the wall of the line, the wire-reinforced hose does not collapse during vacuum operation, maintains its full flow cross-section, and guarantees stable, safe operation of the installation. This solution is used in agriculture, construction, transport, and fuel distribution systems, where chemical resistance, mechanical strength, and long service life of the line are important. In Hydron's offer a wire-reinforced hose is available, resistant to oils mineral and fuels, adapted for operation in a wide temperature range and intensive use. The construction based on a mixture of oil-resistant rubber and steel spiral ensures high resistance to vacuum, abrasion, and atmospheric factors. If you are looking for a durable solution for pumping fuel or oil, reinforced hose wire-reinforced from the Hydron offer is a proven choice for professional applications.
