Metering pump flow
Thread Content
The flow rate of the alkali metering pump in our factory is directly proportional to the liquid level of the alkali tank. Under the premise of the same opening, the higher the liquid level, the greater the flow rate. Is the pump broken?
There should be a problem with the pump. Generally, metering pumps are diaphragm-type positive displacement pumps. Their measurement is generally constant, and the flow rate will not increase due to an increase in the inlet pressure head.
Is the pump inlet clogged? The flow meter should have nothing to do with the static pressure head!
Check your metering pump check valve to see if there is any problem
