Alumina is a most commonly used ceramic material for pump components for its low cost and striking durability. Usually pistons made from 99% alumina ceramic are used as an important components in heating, dosing and high pressure pumps used in industrial, food and agricultural applications where corrosion and abrasion resistance are required and service longevity is needed.
Suzhou Jingci Super Hard Materials Co., Ltd, (here after referred to as Jingci and whose website is www.fineceram.com) has been working on production of ceramic piston and piston for more than nearly 20 years and has rich experience in producing and quality control, and can produce pistons and plungers with diameters from 3mm to 240mm and Ra0.25 surface. Jingci has been an outstanding supplier for famous international customers like Karcher, Wilo and AR pump these years.
Jingci is always developing new thoughts and ways on the production of ceramic parts so as to provide qualified and economic products for customers’ critical-service application.
