Metering pump in the metering medium and working pressure to determine the case, by adjusting the stroke length L and stroke frequency F can be achieved on the two-dimensional adjustment of the metering pump output.

Attention should be paid to the calibration and calibration of the flow when the metering pump is used for the first time. The metering pump has passed the performance test of clean water at normal temperature when leaving the factory, and the test results and flow calibration curve are listed in the certificate.

The dosing device is configured in the mixing box according to the required concentration of the drug, and after being stirred evenly by the stirrer, it is put into the solution box, and the prepared solution is delivered to the dosing point or the designated system by the metering pump.
