I need to select a Acid dosing pump (HCl 30%) for regenration of cation exchanger in demin plant. Capacity of the pump is 4300 LPH @ 5 barg discharge Pressure, we have checked for diaphragm pump with PVDF liquid end, but maximum flow per head is 2400 LPH & we need to consider double head pump, which is costly, hence please let me know if Non Metallic Sealless pump can give the desired discharge pressure as stated above. We dont want to go for metallic pump due to high cost as MOC will be Hastelloy for HCl.
