Everyone can use a metering pump, but if you use it often, do you forget to clean it? If not, the application will be affected.

The metering pump manufacturer will tell you in detail how to clean the metering pump. When applying the metering pump, the connection between the pipeline and the valve should be regularly maintained, and the valve should be cleaned every 3 months to prevent obstruction (the cleaning time can be adjusted according to the characteristics of the drug, such as the application of grain size drugs must be cleaned once a month). When the metering pump does not operate for a long time, it should be cleaned before application.

Metering pump cleaning process: 

1, first clean with water for about ten minutes, and then evacuate it for about five minutes, it is significant that the water in the tube has been drained, and the disassembly posture has just begun to reduce the risk

2, turn off the switching power supply circuit of the metering pump, and remove all valves (when disassembling and assembling, it is necessary to pay special attention to the remnants of drugs and water to prevent damage or splashing on the switching power supply circuit and other related machinery and equipment and cause damage)

3, clean the valve and valve parts with water

4. Check whether the parts are damaged, deformed, split, etc. If so, please carry out disassembly and replacement

5. Install all valves again

6, according to spraying water five minutes to carry out the test (if there is crystallization, please apply crystal paint thinner for about ten minutes, then change to water for five minutes).

Friendly reminder from metering pump manufacturer: When carrying out cleaning posture, please wear safety protective clothing (goggles, rubber gloves, etc.); The valve of the metering pump is made of plastic. Avoid using common tools during disassembly and assembly to prevent damage to parts. Liquid in accurate measurement certification is very volatile; The proportion of accurate measurement certification liquid is relatively large
