WINKLER Scraper: For Fast and Effective Removal of Filter Cake

When fine dust, dirt, and other particles are filtered from liquids, they gradually accumulate on the filter surface. Over time, this buildup forms a so-called filter cake. Initially, the filter cake can improve filtration performance. In the medium term, however, it also increases flow resistance. As a result, the volume of filtered liquid decreases while the energy consumption of the system rises.

To maintain efficient operation, the filter cake must be removed regularly. One of the fastest, most cost-effective, and most efficient methods is mechanically scraping off the deposited filter cake. And how is this best done? With one of the proven WINKLER Scrapers, of course.

Durable Scrapers for Industrial Applications

The scrapers in our product range are made from robust, high-quality plastic. This makes them particularly durable and versatile. In addition to removing filter cake, they are also well suited for stirring and cleaning tasks, for example in the food processing or coatings and paint industries. For many years, companies in the chemical and process engineering sectors have also relied on WINKLER scrapers with great success.

Not All Scrapers Are the Same

It’s true: scrapers used for removing filter cake are not highly complex technical products. Nevertheless, there are important differences you should be aware of. That’s why we offer our scrapers in two distinct versions, tailored to different applications.

• Blue Scrapers (PE-MD – medium density):
  Ideal for cleaning filter cloths in filter presses. Despite their firmness, they offer a certain degree of flexibility, which helps prevent damage to sensitive components of the filtration system during scraping.

• Red Scrapers (PE-HD – high density):
  Designed for cleaning tanks, system components, and filter cloths in filter presses. They are harder and less flexible than the blue version, but significantly more resistant to wear and therefore offer a longer service life.

No matter which version you choose, both scrapers are simple yet reliable and highly effective tools for removing filter cake from your filtration systems.
