Filter cloth for filter presses
Our filter cloths are manufactured especially for horizontal chamber and membrane filter presses of all kinds, up to a plate width of 3 metres. The plastics, yarns and bonds used, and an innovative and perfect design, correspond with your production processes. This allows us to generate an excellent cake-release performance, a clear filtrate, a dry cake, maximum throughput and the longest service life for your applications. In addition, filter cloths have high chemical resistance and the best mechanical resistance with a low level of stretching.
We offer a vast range, from the finest to the coarsest separation performance, tailored to suit your specific requirements, and we can put it all together in the fastest time possible. Benefit from our specialists’ wealth of experience. Make use of the expertise we're gaining every day.

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