Zirconia ceramic plunger pump is a pump made of high-purity zirconia ceramics, with the main features including:

1. Material characteristics: zirconia ceramic plunger pump has the characteristics of high hardness, wear resistance, corrosion resistance, high temperature resistance, low friction, aging resistance, light weight and biocompatibility. These characteristics make it suitable for fluid transport in various harsh environments. However, it should be noted that zirconia ceramics have brittleness.

2. Application areas: Zirconia ceramic plunger pumps are widely used in the filling and metering of liquid formulations such as water injections, freeze-dried powder injections, oral and external applications. Its measuring components are made of new precision ceramic materials that are wear-resistant, corrosion-resistant, and high-temperature resistant. They have the characteristics of not adsorbing drugs, not reacting chemically with drugs, accurate measurement, and long service life.

3. Structure and principle: The ceramic plunger pump is mainly composed of ceramic measuring components (including ceramic plunger pump sleeve, plunger, slot valve measuring rod), stainless steel inlet and outlet nozzles, and connecting components. Its working principle is to use the linear motion of ceramic columns to generate negative and positive pressure, thereby inhaling and discharging liquids.

4. Performance characteristics: Ceramic plunger pumps have extremely inert metal oxide properties, acid and alkali corrosion resistance, high temperature resistance, and are suitable for repeated disinfection and sterilization under high temperature conditions. Its material has ultra-high hardness, wear resistance, long service life (5-8 times that of chrome plated steel pumps), and has extremely small particle release. In addition, its crystal structure exhibits zero porosity, dense material quality, extremely smooth product surface, low friction, and minimal drug residue.

5. Technical parameters: The filling measurement range and measurement accuracy of ceramic plunger pumps are based on standard products, with a maximum stroke of 6mm to 45mm and a measurement accuracy of 0.1% to 0.5%. Its working temperature is usually divided into 10-45 ℃, and can also be customized according to special requirements.

Manufacturers of zirconia ceramic plunger pumps, such as Dongguan Jundro Ceramics Technology Co., Ltd.股票里怎么用杠杆, provide precision machining and customization services for such products.
