About
ZK SEPARATION (Chengdu ZK Separation Technology Co., Ltd.) is a centrifuge manufacturer headquartered in Chengdu, China. Established in 2018 as a subsidiary of Chengdu West Petroleum Equipment Co., Ltd. (founded 1999), the company operates from a 65,000 m² production facility with over 200 employees including 30+ engineers. ZK has delivered more than 5,000 centrifuges across 30+ countries, producing approximately 400 units annually with bowl diameters from 250 mm to 1,000 mm. Their core product lines span decanter centrifuges for wastewater (DDE Series), industrial processing (I Series), and food applications (F Series); disc stack separators for dairy, food, industrial, and marine separation (D/I/F/M Series); and screen bowl decanters for mining and drilling. ZK’s proprietary BD Board technology improves cake dryness and solid recovery in wastewater decanters, while their turbo blowers achieve polytropic efficiency up to 84% for aeration. The company maintains in-house centrifugal casting, CNC machining (lathes up to 4,000 mm), and dynamic balancing to ISO 21940-11 G2.5/G6.3 standards. Applications cover municipal sewage dewatering, mining, chemical processing, food and beverage, palm oil extraction, oil sludge treatment, and pharmaceutical fermentation. A wholly-owned subsidiary, Mountain Processing Company Limited, provides local service from Dammam, Saudi Arabia.
