Seek help regarding the material selection for metering pumps
Thread Content
I would like to ask the experts: how should the materials for the following components of a metering pump be selected? Thank you! Pump head: Which is better, PVC or PP? Safety valves, back pressure valves, Y-type filters: Which is better, PVC or PPH? Thank you!
I found it online – it seems that PPH is better than PVC. But when it comes to use in pump heads, safety valves, back pressure valves, and filters, which one is better? Why? Thank you!
It depends on the type of material; common plastics include PVC, PE, PP, PVDF, and PTFE. Their corrosion resistance is also gradually improving
Thank you for your kind reply. I found online that PPH is better than PVC, but the equipment manufacturers claim that PVC is superior to PPH, saying that PPH is too soft. I’m completely confused.
