Finding the Best Chemical Dosing Pump Technology for Your Application

Often two types of chemical dosing pumps are considered when treating water or wastewater, Diaphragm or Peristaltic.
In these critical applications the chemical feed unit must be able to measure the precise amounts of chemical to meet, but not exceed, chemical demand.
The question is posed, which of these pump types will be most effective and reliable, the diaphragm pump or the peristaltic pump? Both are positive displacement pumps but work in very different ways.

This article discusses the advantage and challenges with both types of chemical feed pump.
