99% Alumina Ceramic Pistons for High Pressure Plunger Pumps
Description:
The ceramic plunger adopts the ultra-hard wear resistance of modern engineering ceramic materials, and can be assembled by ceramic metallization bonding, welding, inlay and socket technology. It is an ideal substitute for similar metal pumps and has been widely used in medical equipment, environmental engineering, petroleum, chemical and other industries.
