The NFM Elastomer belt is the “heart” of the Horizontal Vacuum Belt Filter. With the filter cloth on top to capture the solids, the liquid passes through the filter cloth into the drainage grooves of the belt and through the vacuum holes in the belt into the vacuum pan and the piping to the vacuum receiver and filtrate pump for a continuous operation.
NFM makes vacuum boxes for the Horizontal Vacuum Belt Filters out of mild steel to the many exotic metals. Vacuum boxes can be rubber or urethane lined for maximum wear characteristics.
Turcon slide strips are a stock item at NFM.
Turcon slide strips come in 2 sizes – 1/4” wear surface and 3/8” wear surface.
This is the slide/guide for Horizontal Vacuum Belt Filters with wear belts that make the vacuum seal.
This is the slide/guide joint for the wear belt system.
This is the slide/guide end strip that is adjustable for the wear belt system.
Many of the older Horizontal Vacuum Belt Filters had deckles to prevent side leakage. The seal between the deckle and the filter cloth is the deckle seal material. To keep the water distribution even many wash boxes are equipped with a wash box seal.
