Alumina Ceramic Plunger Precision filling for Food and Cosmetics Industry

Product details

 Alumina ceramic filling pump is a precision fluid delivery device that uses high-performance ceramic materials (such as zirconia ceramic and alumina ceramic) as core components, specifically designed for the transfer and precise dosing of liquids with high hygiene, high corrosiveness, or high-precision requirements.

Compared with traditional metal or plastic pumps, its ceramic components offer excellent wear resistance, chemical inertness, and sterility, making them capable of withstanding corrosive media, particulate suspensions, and high-temperature sterilization.

The working principle of alumina ceramic pump is usually based on mechanical reciprocating motion or pneumatic drive, controlling the flow through the precise fit between the ceramic plunger and sleeve, and achieving closed-loop control with sensor feedback to ensure filling accuracy can reach micro-level precision.

The hardness of the ceramic material (HRA 88 or above) and low friction coefficient (0.02) allow it to operate for long periods without lubrication, avoiding leakage problems caused by wear in metal pumps. At the same time, its surface smoothness (Ra ≤ 0.1 μm) and high-temperature resistance (can withstand sterilization with steam above 140°C) perfectly meet the sterile requirements of industries such as pharmaceuticals, food and beverages, and cosmetics, ensuring no contamination, no leakage, and an error rate as low as ±0.5%, while its lifespan far exceeds that of traditional metal pumps. The commonality of these scenarios lies in the ultimate pursuit of 'precision, purity, and stability,' and ceramic pumps are the best technological carriers for this demand.

The core ceramic material of ceramic filling pumps must have ultra-high hardness, wear resistance, chemical inertness, and biocompatibility.

Aluminum oxide ceramic plungers are particularly suitable for conveying low to moderately corrosive media in the food and chemical industries.Ceramic filling pumps can be divided into various types based on working principle and structural design, each suitable for different viscosity, accuracy, and hygiene requirement scenarios.

The core operation involves the ceramic plunger performing reciprocating linear motion within the pump body, with liquid intake and discharge achieved by changing the volume of the pump chamber.

Wear-resistant ceramic plungers, as one of the main components of plunger pumps, work in conjunction with plunger sleeves.

Ceramic plunger is a shaft-type component with a regular shape, high dimensional accuracy, and high geometric precision.

Precision ceramic plungers are precision industrial components made from ceramic materials such as alumina, zirconia, and silicon nitride, and they possess characteristics such as wear resistance, high-temperature resistance, and corrosion resistance.

Precision ceramic plungers are piston components made of industrial ceramic materials. Aluminum oxide ceramic plungers use the ultra-hard and wear-resistant properties of modern engineering ceramics and can be assembled and formed through ceramic metallization bonding, welding, inlaying, and sleeve fitting techniques.

Alumina ceramic plunger is manufactured through high-temperature sintering and precision machining processes, can replace metal plungers, and is widely used in the Pharmaceutical manufacturing, new energy batteries, semiconductor manufacturing, food and beverages and cosmetics, chemical and petroleum industries.

Material and Process Characteristics of ceramic pump: Physical Properties: High hardness, good wear resistance, low thermal conductivity, good chemical stability, and high corrosion resistance.

Chemical Properties: After corrosion resistance and acid-base safety performance testing, all indicators have reached the level of comparable foreign products.

Processing Technology of alumina ceramic piston: Chemical ceramic plungers are made of high-performance technical materials, formed by cold isostatic pressing and sintered in an ultra-high-temperature furnace. Through high-temperature sintering at 1600°C and isostatic pressing techniques, the products are corrosion-resistant and high-temperature resistant.

During use, they do not soften, crack, or peel, and have a long service life. Alumina plungers can be used continuously at temperatures below 1600°C.

We strictly control every step from alumina ceramic materials to product processing, ensuring high processing accuracy.
