Mechanism and Principle of Ceramic Plunger Pump
A. The ceramic plunger pump is composed of ceramic metering components (including ceramic plunger pump sleeve, plunger, slot valve metering rod), stainless steel inlet and outlet nozzles, and connecting components.
B. The working principle of zirconia ceramic plunger pump
1. The downward linear activity of the ceramic column breeds negative pressure and sucks in liquid;
2. The upward linear activity of ceramic columns breeds positive pressure and squeezes out liquids.
Good performance of ceramic plunger pumps
1. Extremely inert metal oxides, resistant to acid and alkali corrosion, high temperature resistance, and compliance with repeated disinfection and sterilization under high temperature conditions;
2. Ultra high material hardness: wear resistance, long service life (5-8 times that of chrome plated steel pumps), and minimal particle release.
3. The crystal layout exhibits zero porosity and dense material quality: the product appearance is extremely smooth, with minimal friction and minimal drug residue;
4. Minimal thermal expansion: The plunger gap is smaller, allowing for continuous operation without liquid, higher filling accuracy, and online washing and sterilization.
