Manufacture of a wide range of technological products, mainly made of PP, PVDF, TPE, NBR and EPDM, complete with an extensive list of accessories, intended for the most diverse applications related to solid-liquid separation: Press filters, tank filters , thickening equipment, etc …

LENSER is the world leader since 1969 in manufacturing filtration elements for solid-liquid separation. As experts, LENSER has an excellent reputation in this field. Today, polypropylene membrane filter elements, developed by LENSER in 1977, represent the optimal solid-liquid separation technology in press filters. The LENSER Research and Development department builds on these years of experience and continuously improves the LENSER filter elements to meet the new requirements. The wide range of products and extensive knowledge of the industry allows you to be a valuable partner worldwide in solid-liquid separation.

LENSER exclusively manufactures filtration elements by using pressing methods with a controlled program. This allows high repeatability, consistent quality and deformation-free elements. Unlike other manufacturing methods, pressing prevents the orientation of linear molecular chains and therefore does not produce breakage lines with high fragility, which can cause problems in the filter elements. The manufacture of thin membranes with sufficient flexibility is only possible using pressing methods.

The LENSER filter elements are made of different materials, by polypropylene membranes, the company uses specifically developed polypropylenes.

Application areas:

Chemical industry: aluminum oxide, battan earth, dyes, enzymes, phosphates, pigments, silicates, titanium dioxide, zeolite, etc.
Food: Agar-agar, beer, bio-fuels, fats, gelatin, oils, palm oil, proteins, starches, wine, sugar, etc.
Mining: Aluminum, lead, iron, earth, gold, coal, copper, nickel, pyrite, noble land, silver, uranium, zinc, etc.
Minerals: battan earth, gypsum, potassium salts, kaolin, gypsum, lithium chlorite, phosphate, porcelain and ceramic materials, clay, etc.
Dehydration of biological sludge from industrial or urban treatment plants.
The LENSER membrane filter elements facilitate the mechanical compression of the filter cake after the filtration process.

The chamber and membrane filter elements allow the washing and / or blowing of cake according to the circuitry configuration of the filter package.

Below is an animation of the cake washing process of the LENSER membrane plates.

The high pressure membrane filtration elements KM, HD (HD = high pressure) are extremely resistant. These filter elements withstand compression pressures of up to 30 bar thanks to their special feed channel and material combinations.

Interchangeable membrane filter elements facilitate membrane exchange. This means that you only have to change the membrane instead of changing the entire filter element when the filter elements are worn. The body of the plate is preserved.

The chamber filtration elements represent efficient standard equipment for filtration processes of low dry solids content requirements. LENSER supplies them in different sizes and materials for open and closed discharge.

Plates and frames are a popular solution for special processes. LENSER manufactures them according to your requirements in different sizes and designs.

LENSER accessories by filter elements are continuously manufactured and optimized according to the daily experience of LENSER.
