High temperature resistance: the maximum temperature resistance is 800°C, and the melting point is 2850°C
Advantages of ceramic plunger pumps:
1. The ceramic plunger pump adopts high-performance technical ceramic material, which has the properties of high hardness, wear resistance, high temperature resistance and corrosion resistance. To ensure reliable material performance.
2. The microporous structure obtained by the unique processing method on the working surface of the ceramic plunger pump has a self-lubricating effect, which changes the mechanism of sliding friction and lubrication of the traditional plunger pump.
3. The surface of the inner cavity adopts a fluid structure, without dead ends and grooves. The surface of the inner cavity and the surface of the plunger are processed to a mirror surface by an advanced high-precision inner and outer cylindrical grinder, and the outer surface is vibrated and polished, which is convenient for cleaning and disinfection.
4. The structure of the pump body is finely sealed with the product structure, which is convenient for disassembly.
5. These products have been tested for corrosion resistance, acid and alkali resistance and safety performance, and their various indicators have reached the level of similar foreign products.
