Pressure Nutsche Filters

Nutsche ManualDurco Filters Pressure Nutsche Filters are a special type of pressure leaf filter. They have vertical vessels with one horizontal leaf. The single, horizontal leaf allows for fast and easy cake discharge and facilitates interrupted service flows. Multiple process steps such as washing and drying can be performed in the same vessel.

Pressure nutsches can handle a variety of flow rates and solids loading that can be discharged in dry or slurried form. They can be designed for pressures up to 300 psi (2068 kPa) or full vacuum. Pressure nutsches are ideal for lab, pilot or batch applications and for easily filtered material such as carbon particles, salts and other products where a cake thickness of 6 inches or more can be attained.

Special designs are available to meet your specific needs: hinged bottom and top-opening head, small units with hinged cover and stationary filter element, and a conical bottom and arrangements for internal sluicing.

These versatile filters can be constructed of a variety of materials including carbon steel, stainless steel, titanium and hastelloy. They can also be lined with rubber, Polypropylene and Kynar.
