Abrasion-resistant PU hoses (PUR spiral hoses) for sand, gravel, and rock
Where Sand, Gravel, and Stone Put Conveyor Hoses to the Test
In sand and gravel pits, quarries, and conveying systems, abrasion-resistant PU conveyor hoses are constantly put to the test. In feldspar processing, approximately 3-meter-long hoses extract moisture from the raw material. The Master-PUR Performance remains stable even with fluctuations in negative pressure; its smooth inner surface helps flush particles out with the water. The result: fewer deposits and a stable extraction process.
PU Hoses for Bulk Materials (PUR Spiral Hoses) for Plaster, Mortar, and Dry Mixes
Fine grain size, high friction during continuous operation
In plaster and mortar plants, abrasive quartz sand places particularly heavy demands on conveyor lines. In one real-world case, sand up to 0.4 mm in size had severely worn down a metal pipe after a bend. A Master-PUR Inline spans the 2.8-meter-long conveying section. The smooth inner lining provides protection within the material flow, and the precisely fitted loose flange facilitates installation.
Abrasion-resistant PU hoses (PUR spiral hoses) for construction debris and concrete dust
Abrasive Material = Severe Wear?
In construction debris processing, both the suction hose and the connection must be wear-resistant and easy to maintain. In a concrete dust extraction system, a MASTER-PUR L TRIVOLUTION in DN 80 with a screw-on Combiflex PU conical flange replaced a hose that was wearing out too quickly. In this application, significantly better durability, easier installation, and a considerably longer service life have been documented.
PU Hoses for Bulk Materials (PUR Spiral Hoses) for Suctioning Bulk Materials at Construction Sites Using Mobile Suction Excavators
Full suction power under the toughest conditions
On construction sites and in road and civil engineering projects, hoses for suction excavators transport soil, gravel, stones, sludge, and water under high vacuum pressure. When exposing water, gas, or electrical lines, a PUR-HX hose system ensures the moving suction line remains abrasion- and vacuum-resistant. This allows for targeted soil extraction—with minimal disruption and a reduced risk of damaging existing lines.
Abrasion-resistant and microbe-resistant PU hoses (PUR spiral hoses) for municipal cleaning
Flexible in use, easy to handle, robust in material flow
In street sweepers, abrasion-resistant PUR suction hoses transport leaves and dust as well as gravel, glass, and stones. Typical diameters ranging from 200 to 400 mm ensure a free flow of material; high compressibility allows the hoses to conform to brush systems, lifting mechanisms, and suction arms. The lightweight design of the hose systems makes them easy to handle in daily use. Their resistance to microbes and hydrolysis ensures that the extraction of damp residues is safe and poses no health risks.

PU Hoses (PUR Spiral Hoses) for Asbestos Disposal
PU hoses (PUR spiral hoses) are used in specialized vacuum systems for asbestos removal. These hoses are subject to strict regulations and are manufactured to ensure they do not leak or tear. Masterflex Group offers a wide selection of different material variants that are flexible, robust, and abrasion-resistant. They are therefore suitable for most extraction systems on construction sites, in production environments, or in remediation projects.
PU Hoses (PUR Spiral Hoses) for Construction Sites, Bulk Materials, and Construction
Wherever sand, gravel, crushed stone, cement, minerals, and rock are extracted or extracted by suction, specialized bulk-material PU hoses (PUR spiral hoses and connection systems) are subjected to extreme stresses. Highly flexible, abrasion-resistant PU suction and conveying hoses (PUR spiral hoses) offer high resistance to abrasion and vacuum and ensure a reliable material flow and the necessary flexibility in demanding continuous operation in the construction industry, the aggregates industry, and in suction and vacuum excavation technology, a reliable material flow and the necessary flexibility for demanding continuous operation.
PU Hoses (PUR Spiral Hoses) for Glass and Ceramics Manufacturing
Specially designed, abrasion-resistant PU suction and conveyor hoses (PUR spiral hoses) are used for transporting glass and ceramics, particularly in the form of shards, sand, beads, or powders. The PU hoses are designed to withstand the high levels of abrasion (wear caused by friction) resulting from contact with hard materials. Our specially developed, abrasion-resistant PU hoses therefore play a crucial role in the reliable transport of glass and ceramic materials.
PU Hoses (PUR Spiral Hoses) for Municipal Cleaning
High-performance hose solutions featuring PU hoses (PUR spiral hoses) for municipal, environmental, and industrial cleaning from the Masterflex Group: Our PU hoses are designed to withstand constant movement, abrasion, and moisture, offering maximum reliability and flexibility for street cleaning, grass or leaf vacuuming, and the disposal of green waste. They are made of high-quality polyurethane (PU/PUR), are flexible and durable, and help reduce downtime and maintenance costs.
Our hoses, made of polyurethane, share one common characteristic: significantly greater abrasion resistance than rubber or soft PVC—measured in accordance with DIN ISO 4649 (Determination of Abrasion Resistance). Many polyurethane conveying and suction hoses also feature a transparent wall—allowing you to keep an eye on the material flow inside the hose at all times and detect malfunctions early on. All of our polyurethane suction and conveying hoses are also free of halogens and plasticizers.
In addition to these more general properties, we enhance the polyurethane material in many standard hoses with additives to provide further, customized properties. 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 meet the safety requirements of the Holz-BG (BGI 739-2).
Polyurethane is also one of the materials to which we add conductive carbon black or other additives. From such electrically conductive materials, we manufacture conductive hoses, some of which you can also find in this product group.

Do you have questions about our PU hoses (PUR spiral hoses) and connection systems? You'll find the answers here!
Can bulk-handling PU hoses (PUR spiral hoses) be adapted to a specific application?
Yes. Masterflex combines suitable hose types, connection technology, and application-specific engineering to tailor solutions to the medium, process, and installation conditions. PUR HX and PUR Performance are highlighted as key products for the campaign.
What connection method is suitable for bulk PU hoses (PUR spiral hoses)?
The appropriate connection depends, among other factors, on the medium, vacuum pressure, installation situation, and mounting requirements. Depending on the application, options may include, for example, Camlock, flange, screw, or custom connection solutions.
When are antistatic or electrically conductive bulk material PU hoses (PUR spiral hoses) required?
In applications where electrostatic charges can build up during material transport, appropriately designed hoses are required. The appropriate type depends on the material being conveyed and the specific process requirements.
Why are bulk PU hoses (PUR spiral hoses) often used for abrasive media?
Polyurethane combines high resistance to abrasion and wear with flexibility and a comparatively low weight. As a result, PU hoses are particularly well-suited for demanding conveying and suction applications involving abrasive media.
Which bulk material PU hoses (PUR spiral hoses) are suitable for dredgers and vacuum systems?
Suction dredgers require flexible, abrasion-resistant, and vacuum-resistant suction hoses. They must reliably extract soil, gravel, sand, and stones while withstanding movement and varying installation conditions.
Which PU hoses (PUR spiral hoses) are suitable for abrasive bulk materials such as sand, gravel, and stone?
Highly abrasion-resistant PU suction and delivery hoses are particularly well-suited for highly abrasive media. Depending on the load and application, heavy-duty or super-heavy-duty hose types such as Master-PUR Performance or Master-PUR HX are used.
