Centrifugal Pump Versus Air-Operated Diaphragm Pump

We have an old wastewater pretreatment system for our metal finishing operation. The system contains two large air diaphragm pumps that transfer the wastewater from a holding tank to the flocculation tank before the clarifier. Since we are renovating the pretreatment system to extend its life, our team is arguing over whether to replace or keep these pumps.
