Ceramic plunger pump FAQ
Date：2019-01-16 browse：575
Is the ceramic plunger fragile?
Ordinary ceramics are very sensitive to mechanical impact, in order to solve this problem, we have modified the ceramic material, which not only has high hardness,
high wear resistance but also has good toughness. It is a relatively hard and impact-resistant material, thus solving the defects of fragile ceramics.
Ceramic liquid injection pump production process?
Simply put, ceramic pump production is divided into three steps:
The first step: select the appropriate formula to produce the ceramic material that can meet its functional requirements, and burn it into wool embryo;
The second step: the use of special equipment, the ceramic embryo for preliminary processing and precision processing, to meet the requirements of geometric size;
The third step: Assemble the precision ceramic parts and stainless steel parts, and test their functionality and tightness.
What are the advantages of ceramic liquid injection pumps?
(1) Extremely inert metal oxides, acid and alkali corrosion resistance, high temperature resistance,
suitable for repeated disinfection and sterilization under high temperature conditions;
(2) Ultra-high material hardness: wear resistance, long service life (5-8 times of chrome-plated steel pump), minimal particle release;
(3) Crystal structure shows zero porosity, material density: the product surface is extremely smooth, minimal friction, minimal drug residue;
(4) Minimal thermal expansion: the plunger gap is smaller, the liquid can be continuously operated, the filling accuracy is higher,
and online cleaning and sterilization can be realized
Compatibility of ceramic material and product?
Ceramic materials are extremely inert inorganic oxide materials, which have a high surface finish after precision machining, higher than GMP standards.
We can provide ceramic sample suppliers for relevant tests.
Can ceramic pump replace the original stainless steel pump and glass pump?
Yes, when our ceramic pump replaces the original stainless steel pump and glass pump, there is no need to make any changes and adjustments to the filling machine.
How to choose the type of pump?
Different equipment manufacturers, the use of the driving method is not the same: the filling accuracy of the mechanical drive is worse than that of the servo motor drive,
in order to ensure the measurement accuracy, we recommend that the maximum measuring range of more than 3/4 of the use: such as the pump loading range of 1.5-6.9ml,
it is recommended to use above 2.0, higher measuring accuracy.
Can ceramic pumps be used for filling and metering of crystalline and suspended products?
For most crystallized and suspended products, our ceramic pumps can be used. However, we suggest that before ordering the pump,
provide a sample of the product and a description of the filling of the product, we will conduct a simulation test,
through the experiment to design and customize the solution suitable for the packaging and measurement of the product.
Can ceramic pump work at high temperature?
Yes, ceramic pumps can work at high temperatures. However, you must be informed of the working temperature when purchasing the product,
and we will choose the material and assembly parameters according to your requirements to meet your working conditions.
Our standard product is 15-40℃ operating temperature, ceramic pump out and cleaning must be at this temperature before the rod into the pump sleeve.
Can ceramic pumps be autoclaved?
Yes, ceramic pumps can be autoclaved, but the pump must be disassembled before autoclaving.
Why does the ceramic pump turn black after contact with stainless steel?
Because the ceramic material is harder than stainless steel, such as collision or contact between the two, stainless steel will adhere to the ceramic,
can not be removed! Non-metallic materials are recommended as cleaning and loading containers.
Ceramic pump service life?
Ceramic pump service life is affected by many factors:
(1) Materials used in the pump;
(2) the clearance of the pump when leaving the factory;
(3) Mechanical properties;
(4) the composition, particle size and hardness of the drug;
(5) sterilization methods and control parameters;
Due to the extremely high hardness of ceramic materials, it is difficult to wear, and the number of movements is only a small amount of wear (< 0.0002mm) within 10,000 million times;
However, as the number of sterilization increases, the impact resistance of the ceramic material decreases (the number of sterilization is less than 2000,
the impact resistance decreases). In addition, the performance of filling machines from different manufacturers is different, and the service life is greater than five years.
Ceramic pump hug dead, how to do?
Most of the reasons why the pump is locked are because there are large particles or liquid residue that are not removed in the pump. You can use heating, ultrasonic,
and cooling in the refrigerator to separate the locked parts; If the above can not be separated, you can use mechanical external force,
the use of copper rod, but pay attention to the strength.
Can ceramic pump be repaired?
Yes, the ceramic pump is repairable. The ceramic column and sleeve can be repaired or replaced, but the column and sleeve must be matched again and match the internal structure of the original pump.
How to clean ceramic pump?
Ceramic pump cleaning method is the same as other pumps (glass pump, stainless steel pump), the cleaners available on the market can be used to clean ceramic pumps,
and ultrasonic cleaning ceramic pumps can also be used.
Do ceramic pumps need special care during operation?
Like other high-precision products, ceramic pumps should also be taken care of during use! As long as your method is proper, the impact of the cleaning and sterilization process can not easily damage the pump, or cause it to malfunction during production and use. You can buy the heavy cleaning and sterilization rack produced by us to reduce the operation intensity during cleaning and sterilization. In our product manual, we provide instructions for the use of the pump, cleaning procedures, sterilization methods and conditions of use, and analysis of common faults.
How to buy ceramic pump and pump accessories?
Our pumps have been created before the factory information file, please provide the pump information according to the method on the manual, we can provide parts or new pumps within a week.
