Pump selection
Thread Content
Q=3m3/h, H=15m, 30% salt acid dosing pump – should a metering pump or a centrifugal pump be chosen? ? Material requirement for overcurrent components: PVC
Are there metering pumps with such high flow rates? ? ? May I ask everyone
Centrifugal pumps work as well, and metering pumps work as well.
Although the largest one here is 2.7, I’m sure there must be a 3 as well
If the requirements are not precise, choose a centrifugal pump; metering pumps are also not cheap
If the requirements aren’t high, it’s fine to choose a fluoroplastic pump as long as its parameters meet the needs
Centrifugal pumps come with this parameter; vertical multi-stage stainless steel pumps can be chosen, such as Grundfoss’ CR, Sullair’s SV, and Nantong’s CDR, among others.
This is a natural selection magnetic pump or pneumatic diaphragm pump
See what requirements there are for measurement accuracy. . If no special requirements are there, a fluoroplastic centrifugal pump will suffice. . If there’s a requirement, go with a metering pump. .
A metering pump is essentially an electric diaphragm pump; choosing a diaphragm pump will suffice, with the control frequency being handled electrically and the volume of air flow being controlled via air.
Oh, and screw metering pumps, plunger metering pumps. :lol
