How high can the metering pump pump pump

How high the metering pump can pump depends on the performance of the pump type. Users can determine the head and suction of the pump type when selecting the type to ensure compliance with the transportation standard. At present, the theoretical suction of the metering pump is less than 3m, which can meet the needs of most projects. If there are special process transportation needs, you can also contact the manufacturer in advance to customize the non-standard pump type. For details, please refer to the following contents. As for how high the metering pump can pump, there are different suction and head performances according to the pump type specifications. The higher the theoretical parameters, the higher the pump can be pumped. Generally speaking, the higher the head can be achieved under low flow and the higher the suction can be achieved under the condition of single medium composition. If the suction is poor and the lift is not up to standard when using the pump, the following problems can be considered. 1. The viscosity or solid content of the transported medium exceeds the transportation standard, which will cause part of the medium to adsorb on the pipe wall, or particles to block at the one-way valve, thus affecting the suction range of the metering pump. The corresponding treatment method is to check and clean the one-way valve and pipeline, and replace the metering pump with a higher standard or dilute the viscosity of the medium according to the actual situation; 2. The installation is too careless and the installation position is not selected correctly. For example, the height of the metering pump is too high and exceeds the suction range. Therefore, it is necessary to adjust the installation height and leave a certain space on the side of the pump. In addition, consider whether the suction range is affected due to excessive pipe bending; 3. Air enters the body fluid cylinder of the pump, which makes the pressure in the pump unable to form effectively and affects the normal startup. Not only the suction lift, but also the parameters such as flow and head will decrease significantly, and occasionally there may be abnormal noise. This problem can be solved only after exhaust.
