plunger ceramic pump is a type of positive-displacement pump where the plunger is made from wear-resistant ceramic (alumina or zirconia), offering high precision and durability.

icro Ceramic Pumps equipped with plunger ceramic components are gaining widespread popularity in modern precision dosing systems. Their compact structure, chemical stability, and extended lifespan make them ideal for high-accuracy fluid control across pharmaceutical, cosmetic, and laboratory applications.

​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.
