USFilter JWI Products technical representatives will recommend the proper J-Press for your specific needs, based upon prior experience oractual testing of the material.
A filter press utilizing sidebar construction features has several advantages that distinguish it from the other common style of construction known as overhead suspension. Both styles offer certain advantages to the user. In either case the term sidebar or overhead refers to the method of supporting the filter plates.
When a filter press is built as a sidebar design, the filter plates, which are usually plastic or steel, are suspended from the side rails that form the connecting members of the press. The side rails are often capped with a smooth, non-corrosive material such as stainless steel or plastic and provide a smooth surface for the filter plates to slide on. The ability of a plate to move freely makes it easier for the operator to discharge material from the press. These rails connect the head end of the press (the end where the liquid slurry enters and exits the press) and the cylinder bracket end (the end that contains a hydraulic cylinder to keep the press closed when subjected to the high pressures produced by the feed slurry pump). Side rails may be of tubular material, either rectangular or round, and are often produced from solid steel, usually with a rectangular cross section.
Sidebar construction is typically used to manufacture smaller size presses. The cost of manufacturing is usually less and many pieces of optional equipment such as plate shifters, cloth washers, or safety devices may easily be mounted to the side rails. On automatic style presses the space between the support legs is often utilized to house a hydraulic control cabinet. Oil reservoirs, hoses, pumps and filters are conveniently located for service but are also protected from accidental damage.
USFilter JWI Products offers a 250mm, .15 ft3 (2.8L) portable, pilot filter press for field testing purposes. These units include a double diaphragm feed pump, interconnecting piping and air blowdown manifold, all mounted on a skid with casters. Tests can be performed to produce different cake thicknesses, utilizing a variety of filter cloth types and feed pressures. When testing is completed a complete report is provided that shows what a J-Press can accomplish for you.
Lightweight polypropylene plates are standard on most sidebar J-Presses. They are generally accepted by the industry as the worldwide material of choice for most applications because they exhibit good chemical resistance, and provide long service life under a broad range of temperatures and pressures.
Filter cloths are made of polypropylene, polyester, cotton and other materials and come with a variety of weave patterns depending on application and desired results.
