Jingjin Equipment Inc.
About
Jingjin Equipment Inc. is a Chinese manufacturer founded in 1988 that has grown into the world's largest filter press producer by production volume and sales, holding that position for over twelve consecutive years. The company operates from a 900,000-square-meter facility with approximately 4,000 employees, including 130 senior engineers and a 105-person process engineering team. As the primary drafter of China's national standards for filter presses and filter plates, Jingjin holds 136 patents (132 domestic, 4 international) and manufactures virtually all filter press components in-house, from filter plates and filter cloth to hydraulic systems and electrical control cabinets. Their filter press lineup spans chamber, membrane, and plate-and-frame configurations, including automatic fast-open models for rapid cake discharge, stainless steel sanitary-grade units for chemical and pharmaceutical use, PLC-controlled fully automated presses for unattended operation, and high-pressure membrane presses rated to 4.0 MPa. The multi-disk screw press provides continuous sludge thickening and dewatering for low-concentration sludges as an alternative to centrifuges. Jingjin's filter cloth is woven on 180 German DORNIER looms in a climate-controlled environment, and their plunger pumps deliver the high-pressure feed required for filter press operation. Additional products include high and low voltage electrical cabinets and ASME-compliant pressure vessels. With a global network of 150 domestic and 135 overseas service personnel, Jingjin serves mining, metallurgy, chemical, pharmaceutical, food, papermaking, electroplating, ceramics, and municipal wastewater sectors across more than 130 countries.
