T H E TA S K Efficiency, profitability and environmental sustainability Efficiency, profitability and environmental sustainability are increasingly setting the requirements for liquid/solid separation filter technology in all areas of industry. The primary consideration is protecting high-value capital plant from damage caused by system contamination. This requires efficient technical solutions which minimise the capital, operational and maintenance costs. The duplex filter type BFD meets all these requirements optimally by unique flexible concepts for the filtration of water, machining...

THE CONCEPT An universal series - optimally variable The requirements laid down for a modern double filter With 60 variants and the available housing materials are optimised in the design of the new BFD as a result of (ductile iron, cast steel or stainless steel), the BFD the versatile concept. In addition, the BFD series combi- series provides a flexible filter solution. The flexibility of nes the utmost levels of economy with operational safe- the BFD series is enhanced by compliance with the • Innovative detailed solutions • Flexible, tailor-made modular construction • Functionality that...

THE SOLUTION Unique construction - perfect function Process safety by means of filtration is absolutely funda- loss, high dirt-absorbing capacity and high throughput. mental to filtration technology. On the other hand, the aim The standing or suspended design of the filter elements is also to achieve optimum economy of the process. For underlines the flexibility of the BFD Double Filter series. this purpose, in addition to a constant flow cross-section Depending upon the process requirement, disposable in the housing, which avoids unnecessary pressure losses, elements or filter media, which...
