          • HOSES TECHNOLOGY

          • Markert offers Hoses and hose assemblies for industrial use in the chemical, petrochemical, pharmaceutical and food industries, as well as in plant engineering, by freight carriers or tank terminals.

            Hose assemblies are omnipresent in industrial applications, whether in a refinery or in high-purity pharmaceutical processes: Industrial hose assemblies are used universally. It should be noted, however, that hose assemblies are pressurised components that often carry critical media and vary enormously:

            • PTFE liner material
            • Cover material
            • Vacuum resistance of the hose
            • Abrasion properties of the cover
            • Integration of the fittings
            • Conductivity
            • Approvals for materials used

            In order to reliably rule out any risk to people, the environment and the plant, expert advice is absolutely essential. As the manufacturer, we are your expert and at your side to assist you with advice and action.

            Markert has decades of expertise and offers the widest range of products on the market. Coupled with our large central warehouse and quick response times, we are your contact when it comes to industrial hose assemblies.

            • Hoses

            • From the correct PTFE liner for the medium to be transported, the correct pressure carrier for the operating pressure, the suitable hose cover for the intended application and a stainless steel spiral for vacuum use, we make you the best possible product for your conditions of use – always with the required conductivity. Whether it’s for loading and unloading tankers or for blood plasma applications in a pharmaceutical industry clean room, we will find the perfect hose for you.

              • Hose couplings & hose fittings

              • If a hose is integrated with fittings, this creates what is known as a hose assembly. The variety of materials and designs for hoses is immense, but is dwarfed by the greater variety when it comes to fittings and connections.

                The correct binding technology must be used to connect the hose and fitting. Regardless of whether it's clamp collars, press fittings or PTFE lining: as a manufacturer of hose assemblies, Markert has decades of experience so that every connection proves safe and reliable in use.

                In addition to the fittings and connections listed below, Markert offers a wide range of special connections that can be used to reproduce any plant situation. If necessary, we also manufacture fittings from Hastelloy, for example, or we can create customised designs: we will be happy to advise you.

                • Accessories

                • Due to the wide range of applications for industrial hose assemblies, there are many requirements when it comes to design and handling.

                  Harsher operating conditions such as:

                  • Chafing on floors and edges
                  • "Running over" the hose assembly
                  • Kinking
                  • Lacking the minimum bending radius
                  • Frequent pressure and load changes
                  • High bending cycles
                  • Torsion of the hose assembly
                  • Tensile and compressive loads
                  • Abrasion
                  • High exposure to UV radiation
                  • Excessive temperature load

                  can drastically reduce durability.

                  Appropriate additional equipment can increase the durability of the hose assembly and make handling significantly easier.

                  Kink protection, which provides reliable reinforcement for the hose assembly at the insertion point, and heat protection (Pyro), which provides protection against several hundred degrees Celsius, are common additional features. There are also a wide range of other tools and product features, such as:

                  • Hose reel
                  • Hose suspension
                  • Balancer
                  • Abrasion protection
                  • Hose holder
                  • Protection against over run
                  • Impact ring
                  • Swivel joints

                  We will be happy to advise you so that you can get the right additional equipment for your hose assembly.

                    • Rubber Kink Protection Plus
