Stainless Steel Multilayer Filter
The stainless steel multi-layer filter is a stainless steel multi-layer Plate And Frame Filter Press, which is suitable for closed filtration of liquids with a concentration below 50% and low viscosity and less slag content to achieve purification, sterilization, clarification, etc. Filter requirements, direct selection of microporous membrane, can not filter through the microporous membrane filter to achieve the purpose of sterile filtration).
This machine has large filtration area, large flow rate and wide application range, so it is widely used in pharmaceutical, chemical, food and other industries. Structural features: Except for the motor, other parts of this machine are made of 1Cr18Ni9Ti or 316L high-quality corrosion-resistant stainless steel, which is suitable for filtering various pH acid and alkali solutions. Good filtration quality and high efficiency. The filtration part is composed of ten layers of filter plates, with large filtration area and large flow rate; and according to the requirements of different production processes (primary filtration, semi-fine filtration, fine filtration) of the filtered solution, different filter membranes can be replaced, and the production flow rate can be adjusted according to the user. The size of the Filter Plate can be appropriately reduced or increased to make it suitable for production needs, so this machine has the characteristics of a multi-purpose machine with a wide range of applications; the filter plate adopts a flat thread mesh shape, advanced structure, no deformation, easy to clean, It can effectively increase the service life of various filter membranes, thereby reducing and saving production costs. The stainless steel infusion pump equipped with this machine has a small motor and low power consumption. There are rubber wheels under the base, which is easy to operate and flexible to move.
