Our PU transport hoses transport solid, liquid or gaseous media by means of pressure, vacuum or gravitational force. Suction hoses made of PU transport solid, liquid or gaseous media by means of "vacuum". All hoses in our product group "Abrasion-resistant suction hoses and transport hoses made of PU / flame-retardant hoses" are the result of our special expertise in manufacturing hoses made of polyurethanes. In addition to profile-extruded hoses, you will also find film hoses and Miniflex hoses here. Thanks to our manufacturing expertise, you benefit from the advantages of polyurethane in every suction and delivery hose listed here.
MaterialsConstruction & production
A key property of polyurethanes is their high abrasion resistance. These robust material properties are measurably better than those of rubber raw materials and soft PVC. In combination with the design advantages resulting from the construction of the conveyor hoses, polyurethanes form the basis for conveyor hoses that are particularly suitable for suction and conveying with their optimised flow profile.
Our abrasion-resistant PU hoses are used in a wide range of industrial applications.
All of the hoses we manufacture from polyurethane have a number of properties in common. These include, for example, the significantly greater abrasion resistance of polyurethane compared to rubber or soft PVC, measured in accordance with DIN ISO 4649 (determination of abrasion resistance). Many delivery and suction hoses made of polyurethane also have a transparent hose wall, so you can keep an eye on the material flow in the hose at all times and recognise faults at an early stage. What's more, none of our polyurethane suction and delivery hoses contain halogens or plasticisers.
In addition to these more general properties, we equip the polyurethane material in many standard hoses with further customised properties by adding additives. For example, we use polyurethanes with specifically enhanced material properties to manufacture our Flamex hoses. These flame-retardant PU hoses are type-tested in accordance with DIN 4102-B1 and fulfil the safety requirements of the BGI 739-2.
Polyurethane is also one of the materials to which we add conductive carbon black or other additives. We use such electrically conductive materials to manufacture conductive hoses, some of which can also be found in this product group.
Profile extrusion: a flexible manufacturing process for light to (very) heavy conveyor hoses
In terms of design and construction, most suction hoses and conveyor hoses in this product group are profile extruded hoses. We manufacture abrasion-resistant hoses with different wall thicknesses on our extrusion lines:
- LF (light film hoses)
- L (light)
- H (heavy)
- HX (very heavy)
Our product range thus extends from light, highly flexible to heavy, vacuum-resistant hose qualities. The wall thickness makes a significant difference, particularly in the case of extruded spiral hoses, both in terms of compressive strength, bending flexibility and weight. Compared to more rigid conveyor hoses, our extruded conveyor hoses are generally light and easy to handle.
We are constantly working on improving the profile geometry of our extruded transport and suction hoses. For example, we specifically reinforce the zones below the spiral in individual heavy conveyor and suction hoses and thus at the points where wear is greatest during operation. We also equip our inline hoses with an inner wall made of application-optimised 60° Shore A polyurethane as standard. We also hold the patent for the production of these special hoses with their extremely abrasion-resistant and super-strong PU inliners.
Foil hoses as PU suction hoses
Thanks to their compliance with DIN 4102 B1, our film hoses are not only characterised by their many positive properties but are also flame-retardant hoses. They are ideal as extraction hoses for various applications. The design and manufacturing process also differ from profile extruded hoses.
Most of the products within this group fulfil the requirements of TRGS 727 or the ATEX standard. The technical rule for hazardous substances TRGS 727 reflects the current state of safety technology for the avoidance of ignition hazards due to electrostatic charges and the assessment of an ignition hazard of bulk materials.
It deals in detail with electrostatic charges when handling liquids (§ 4 ff.), gases (§ 5 ff) and bulk materials (§ 6 ff). In addition, the TRGS also provides information on which transport hoses may be used when handling the individual media. TRGS 727 distinguishes between aspiration (vacuum conveying) and pneumatic transport (pressurised conveying) of bulk materials.
You should ensure that electrostatic charges are prevented from the outset. For use in potentially explosive areas, you should use our conductive hose types. However, these suction hoses and transport hoses must be earthed via the metal support spiral. Please read our operating instructions.
F&A delivery hoses
A conveyor hose is a flexible hose designed to transport materials from one place to another. Conveyor hoses are often used in industrial and commercial applications to efficiently and safely move various types of solids, liquids or gases. Conveyor hoses can be made of different materials depending on the requirements of the application and the properties of the materials to be transported.
Masterflex offers a wide range of conveyor hoses for various applications and industries. These hoses are characterised by their quality, flexibility, durability and specific properties. Examples of conveying hoses from the Masterflex brand include
- Conveying hoses specially designed for transporting bulk goods, powders or other materials in industry
- Chemical-resistant transport hoses
- Conveying hoses compatible with foodstuffs
- Electrostatic dissipative transport hoses
Masterflex offers a wide range of suction hoses for different applications and industries. In an industrial context, Masterflex suction hoses are also used for the suction of solids. The suction hose can therefore fulfil similar functions to the transport hose. Many delivery hoses can therefore also be used as suction hoses and vice versa. Examples of suction hoses from the Masterflex brand include
- Suction hoses specially designed for transporting bulk goods, powders or other materials in industry
- Chemical-resistant suction hoses
- Microbe-resistant suction hoses
- Permanently antistatic suction hoses
Absolute customer favourites!
They are the absolute customer favourites when it comes to transport hoses: the suction and transport hoses Master-PUR Inline and Master-PUR Performance. They were developed for transporting extremely abrasive media and other problematic goods. These hose solutions are manufactured without internal weld seams and corrugated valleys and are therefore robust, efficient and economical.
Background knowledge: Dust explosion
In production facilities for powdery media, such as starch, unintentional electrostatic discharges can lead to devastating accidents in the form of explosions. Our "EL" type food hoses are ideally suited to minimising the risk of dust explosions - for example in grain mills.
We have written a white paper on the subject of dust explosions.
