CNC Machining 99.5% Alumina Ceramic Ring
Description:
Alumina Ceramic Baffle Ring Seal Ring Thrust Ring Alumina Zirconia Anti-friction Pump Components Circulating Pumps ceramic baffle ring made from 95%, 96% or 99% alumina. The ceramic baffles are anti-abrasive, anti-corrosive, high temperature resistant, can resist shock and heat, so they are often used in circulationg pumps, fountain pumps, as well as other kinds of pumps.
