Abstract: zirconia ceramic filling pump is composed of ceramic measuring parts (ceramic pump sleeve, rotary valve, measuring rod), stainless steel inlet and outlet nozzles and connectors.
Zirconia ceramic filling pump has the characteristics of no pollution to the filling medium, no chemical reaction with drugs, accurate measurement, long service life, etc.
it is widely used in the filling measurement of water injection, freeze-dried powder injection, oral and external liquid preparations.
Next, we will introduce what is the filling pump, the advantages of ceramic materials and the precautions for choosing zirconia ceramic filling pump.
What is a filling pump?
The filling pump is a high-precision liquid filling pump, which is composed of measuring parts (ceramic pump sleeve, rotary valve, measuring rod), stainless steel inlet and outlet nozzles and connecting parts, etc.
the measuring parts of its products are made of new sealed zirconia ceramic materials with wear resistance, corrosion resistance and high temperature resistance.
The port of rotary valve of zirconia ceramic filling pump is aligned with the liquid inlet and the downward linear movement of Tao Cizhu to generate negative pressure, liquid suction,
the port of rotary valve is aligned with the liquid outlet and the upward linear movement of Tao Cizhu to generate positive pressure and liquid discharge.
Precautions for selecting zirconia ceramic filling pump
1. Zirconia ceramic filling pump capacity range: 0.1 ~ 1.5ml, can be customized.
2. The temperature of zirconia ceramic filling pump is 10 ~ 40 ℃, and different materials can be selected according to the specific temperature.
3. Filling accuracy standard of zirconia ceramic filling pump: when the filling volume is less than 1ml, the upper and lower deviation shall not exceed ± 1%;
when the filling volume is more than 1ml, the upper and lower deviation shall not exceed ± 0.5%.
4. The product has been air tight tested before leaving the factory and filling accuracy test has been carried out on the filling machine:
the accuracy test method uses drinking pure water as the medium and adopts the weight measurement method to calculate the average value, upper deviation and lower deviation.
Advantages of ceramic materials
Compared with metal materials, ceramic materials have the following advantages:
1. Ceramic materials belong to environmental protection materials, and their properties fully meet the requirements of hygienic grade of food and drug production standards.
2. The ceramic material has high hardness, good wear resistance, and the ceramic filling pump has little wear in the use process.
3. The ceramic material has high resistance to temperature and acid and alkali, ensuring no damage to the pump itself in the process of cleaning and high-temperature sterilization.
4. With the rapid development of Chinese pharmaceutical enterprises and the increasing demand of pharmaceutical quality, the advanced filling scheme can meet the increasing demand.
