The challenge with vacuum disc filters is that the steel sectors corrode significantly due to the suspension of magnesium chloride after one year of service. This means that they have to be replaced frequently.
Sectors made of polypropylene (thermoplastic resin) were suggested for optimisation since they are corrosion-resistant. The project started with the casting of a blank to check the accuracy of fit in the system. Then production started.For two years now, the segments have been working without any problems with a scheduled service life of four to five years.
Another advantage of the plastic is weight reduction since the density of polypropylene is <1. This has made our customers’ work much easier and has led to valuable progress regarding occupational safety. Thanks to the lower weight, it was also possible to further reduce the wear and energy consumption of the system.
Accurately designed filter bags with lateral zip fastener which fit the plastic sectors were created. The advantage of this is that the sectors no longer have to be removed to change the filter bags.
A special cooling hose needed to be developed in order to protect rubberised metal hoses with internal wiring harnesses and sensors against exterior radiant heat.
The hose can be retrofitted and manufactured in any length desired.
The cooling hose was designed for use in a hot ambient atmosphere (e.g. desert regions, underground mining, mechanical and plant engineering).n.
In addition, wall supports for holding hoses in the pharmaceuticals industry and stainless steel transport trolleys for pharmaceuticals hoses were developed.
In order to handle aggressive media easily and flexibly, you need lightweight, durable hose lines with the lowest possible bending radius. A solid inliner is ideal for keeping interior soiling to a minimum.
The marsoflex® PTFE hose line with diagonally corrugated inliner has a PTFE tube which passes through the fitting and is folded back onto the coupling surface. For one customer, 90% of defective PTFE lines were traced back to damage to the flange. Our fixed PTFE connection can drastically reduce this source of error without needing to forego the benefits of the flexible folded back PTFE line as a result. The significantly increased lifespan of the marsoflex® PTFE lines with PTFE connection ensures an immense cost saving.
We are pleased to inform you that together with the Campagna family we will establish the Markert Italia Srl, with registered office in Milan, on 1 November 2016. All the industrial activities of Perfabrics and FPN will be contributed to the new Company.
The Campagna family is an excellent partner that has considerable experience in the field of filtration. We welcome the entire team around Perfabrics and FPN, and look forward to good cooperation.
Task: Damaged barrel-neck after short period of use + insufficient dewatering properties of cloth.
Markert solution: Polyamide cloth type marsyntex® NKD 2394 combined with a backing/support cloth type marsyntex® PP 2486 gave improved filtration result. EPDM rubber neck eliminated problem in the feeding zone area.
Task: Cake blowing step in the process which can cause serious cloth damage.
Markert solution: impermeable wear protection considerably extends life time of cloth.
