Vacuum disc filters

Task:
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.

The solution: 
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.

Special feature:
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.

Innovative cooling hose

Task:
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.

Special feature:
The hose can be retrofitted and manufactured in any length desired.

Application:
The cooling hose was designed for use in a hot ambient atmosphere (e.g. desert regions, underground mining, mechanical and plant engineering).n.

Pharma

Special project:
In addition, wall supports for holding hoses in the pharmaceuticals industry and stainless steel transport trolleys for pharmaceuticals hoses were developed. 

Long service life thanks to PTFE connection

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 solution:
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.

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.

Minerals & Mining: Specific examples of mining applications

Tailings

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.

Copper Ore Concentrate

Task: Cake blowing step in the process which can cause serious cloth damage.

Markert solution: impermeable wear protection considerably extends life time of cloth.
