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.
