​In pharmaceutical aseptic production, proper cleaning and sterilization of a ceramic filling pump is critical for maintaining hygiene, product quality, and GMP compliance. The key processes used are Clean-in-Place (CIP) and Sterilize-in-Place (SIP), which eliminate residues and microorganisms from internal pump surfaces—especially from the ceramic piston pump components such as the ceramic plunger and pump sleeve.

eramic filling pumps are piston-type metering pumps widely used in aseptic filling equipment. A typical structure includes a ceramic plunger (piston rod), a ceramic pump chamber (cylinder sleeve), rotary or check valves for liquid control, and complementary stainless-steel components (usually 316L). During operation, the ceramic plunger reciprocates inside the pump chamber, drawing and dispensing fluids through precision valves to ensure accurate liquid filling.

Many users of Alumina Ceramics have observed that after prolonged exposure to sunlight, some components begin to show visible discoloration—often a yellowish or dull hue on the surface. While this change does not impair performance, it raises concerns about the long-term stability and appearance of the material.

Aluminum Nitride Ceramics (AlN ceramics) are widely used in high-performance applications due to their excellent thermal conductivity, electrical insulation, and high-temperature resistance. However, some users may notice slight color differences among different batches of AlN ceramics—such as light gray, off-white, or pale yellow shades. These variations are normal and do not affect the material's performance.
