High-Quality Filter Press Plates from China Suppliers | Various Sizes | Factory Direct
Shandong Hesper Rubber Plastic Co., Ltd. supplies various sizes of filter press plates, with sizes ranging from 400mm to 2000mm, suitable for many kinds of filter presses with filter areas from 0.6m² to 1000m². Our filter press plates' main material is reinforced polypropylene, which provides stable chemical properties, strong corrosion resistance, acid and alkali resistance, non-toxicity, odorlessness, lightweight, high strength, and labor-saving operation. These plates are widely used in chemical industry, sewage, light industry, petroleum, manufacturing pharmaceutical, food, metallurgical coal, environmental protection, and other fields.
Hesper’s filter press plates mainly feature two types: (recessed) chamber plates and membrane plates (diaphragm squeeze).
Chamber Filter Press Plate
Chamber filter press plates are utilized in various recessed chamber filter presses and represent the most commonly used plate. The recessed chamber filter plate features a solid structure where both sides of the filter plate are concave, and two adjacent filter plates combine to form a filter chamber.
There are grooves on the surface of the filter plate, and the protruding part is used to support the filter cloth. The main advantages include less loss when feeding, fast filtration speed, high temperature and high pressure resistance, good sealing performance, uniform filter cake washing, low water content, high pressure in each filter chamber, and resistance to damage.
Membrane Filter Press Plates
In order to reduce the moisture content of the filter residue, we also offer membrane filter plates. A single membrane filter plate is composed of two diaphragms and a core plate. The external medium (such as water or compressed air) enters the chamber between the core plate and the diaphragm to make the diaphragm bulge, compressing the filter cavity to achieve better separation and increase solid content.
Solid content can be squeezed a second time after the completion of filtration. This process improves the solid content of the cake, enhances life-span, and reduces energy consumption. They also improve the washing effect, shorten washing time, save washing liquid, and improve the overall quality of the products.
Q: What sizes of filter press plates do you supply?
Shandong Hesper supplies filter press plates in sizes from 400mm to 2000mm, which are suitable for filter presses with filter areas ranging from 0.6m² to 1000m².
Q: What is the main material of Hesper's filter press plates?
The main material is reinforced polypropylene, offering stable chemical properties, strong corrosion resistance, acid and alkali resistance, non-toxicity, odorlessness, lightweight handling, and high strength.
Q: What are the key advantages of Chamber Filter Press Plates?
Chamber plates minimize feeding loss, speed up filtration, resist high temperatures and high pressures, provide excellent sealing, ensure uniform cake washing, and yield low water content.
Q: How do Membrane Filter Press Plates reduce moisture content?
They utilize external media like water or compressed air to inflate the diaphragms against the core plate. This secondary squeeze compresses the filter cavity, significantly increasing the solid content of the cake.
Q: In what industries are these filter press plates used?
They are widely applied in the chemical industry, sewage treatment, light industry, petroleum, manufacturing pharmaceuticals, food processing, metallurgical coal, and environmental protection fields.
