A device used to increase the pressure of the pipeline. When the pressure at the dosing point is lower than the inlet pressure of the metering pump, the outlet of the metering pump must be installed with a backpressure valve to reduce siphonage and self-flowing caused by the overcurrent transport and to ensure that the metering accuracy of the metering pump is not affected.
Material: PVC, PVDF, 304, 316 and so on.
