Hydraulic hoses - types and applications

Hydraulic hoses are used wherever liquids need to be pumped at high pressure. They are an indispensable tool in many industries, such as construction, petrochemicals, agriculture, automotive, aviation, and many others. Their flexibility and durability allow for connecting hydraulic components in hard-to-reach places and transferring fluids under high pressure.

What types of hydraulic hoses are there?

The type of hose used in a given system depends on the pressure at which it operates and the conditions it must withstand. There are many types of hydraulic hoses, which differ in design, materials, and intended use. A different hose will work for a small bearing press, and a completely different one for a pump that drives heavy construction machinery. The basic classification of hoses is:

• Rubber hoses: made of synthetic rubber, reinforced with steel or fabric braiding. Used in medium- and high-pressure equipment
• Thermoplastic hoses: made of thermoplastic materials such as polyurethane or nylon. Lightweight, flexible, and chemical-resistant
• Teflon hoses: made of Teflon (PTFE), characterized by excellent chemical and thermal resistance. Often reinforced with steel braiding
• Steel hoses: made of stainless steel, durable and resistant to high temperatures and pressures. Used in extreme conditions
• Spiral hoses: feature an internal spiral construction, allowing them to be stretched and coiled without damage
• Articulated hoses: consist of segments connected by joints, allowing for free bending and twisting

Various materials for hydraulic hoses

Hydraulic hoses are key components of hydraulic systems, responsible for conveying fluids under high pressure. To withstand demanding operating conditions, they are made from various materials with special properties. The inner layer of the hose, which comes into direct contact with the working fluid, is most often made of synthetic rubber, such as nitrile (NBR) or EPDM. These materials provide excellent resistance to oils, chemicals, and abrasion. The outer layer, which protects the hose from mechanical damage and environmental factors, is also made of synthetic rubber or thermoplastic materials, such as nylon or polyurethane. Between these layers are reinforcing layers of steel wire or textile fibers, which give the hose strength and resistance to high pressures.

In high-temperature applications, hoses with an inner layer of Teflon (PTFE) are also used, which maintains excellent chemical resistance and flexibility across a wide temperature range. Thanks to the appropriate selection of materials, hydraulic hoses can operate reliably even under the most demanding conditions.

What are the applications of hydraulic hoses?

A hydraulic hose is one of the system components used to pump liquids under high pressure. It serves as a connector between the pump and the equipment that needs to be driven. They are made of durable and resistant materials designed for operation in harsh conditions. What’s more, the hoses are also flexible, allowing them to convey fluid throughout the entire system, reaching even the most obscure corners.

Hydraulic hoses are widely used in various industrial sectors. If you want to explore professional solutions and available models, check out the range of Enerpac hydraulic hoses, which stand out for their high quality and reliability.

• Construction: They are used in construction machinery, such as cranes, excavators, and bulldozers, to power hydraulic cylinders that control movement and lift heavy loads.
• Agriculture: used in tractors, combine harvesters, and other agricultural equipment to power hydraulic cylinders that control the movement of implements such as plows and sprayers.
• Mining: used in mining machinery, such as drilling rigs and excavators, to drive hydraulic motors and actuators that control movement.
• Manufacturing: used in manufacturing machines, such as presses and injection molding machines, to power hydraulic cylinders that control the movement of equipment.
• Aviation: used in aircraft to power hydraulic actuators that control the movement of the landing gear, brakes, and flaps.
• Automotive: used in vehicles to power braking systems, power steering, and suspension.

How to choose the right hydraulic hose?

Wondering how best to choose the right hydraulic hose? Consider a few basic factors:

• Type of fluid: the hose must be compatible with the fluid being transported (oil, water, chemicals)
• Operating pressure: the hose must withstand both internal and external pressure
• Operating temperature: the hose material should be resistant to the temperature range in which it will operate
• Hose diameter: it should be selected to match the required fluid flow
• Flexibility and durability: the hose should withstand bending, twisting, and external conditions such as abrasion or UV radiation

Regular inspection and maintenance of hydraulic hoses are essential for maintaining the performance and safety of the entire hydraulic system. Damaged or worn hoses should be replaced immediately to prevent failures and potential damage that could result in significant financial losses.
