Ceramic Plunger & Cylinder for
Pumps
Plunger and cylinders are the wear and tear parts of the plunger
pumps. The metal ones can not meet the complex working condition
nowadays. OeMag ceramic plungers and cylinders have the advantages
of high hardness, wear-resistance, corrosion resisting and
low thermal expansion coefficient, which are widely used in
different types of pumps. The usage life of the ceramic plungers
and cylinders are 5 to 10 times longer than the other types
of material, which gives notable economic benefits. |
