Ceramic pump components include pistons, plungers, wear plates, bushes, liners and sleeves and
mechanical and chemical seal rings. The material is such as super pure Allumina, Zirconia, etc.
These are typically used in jet pumps, water jetting pumps, high pressure pumps and high pressure
water supply pumps, which find tremendous applications in industries including automobiles, chemical
and petrochemicals, foundries, oil refineries, paper and pulp manufacture, cement manufacturing, food
processing, thermal power plants and steel plants etc.
