A centrifugal pump is the most commonly used wastewater pump. They are used most commonly for raw wastewater pumping; at lift stations, recirculation flows, for return activated sludge, waste activated sludge, and final effluent pumping.
The pumps used in small water systems can be divided into two general categories. The basic difference between the two types is their response to changes in discharge. pressure. â¢ Dynamic pumps1 â Dynamic pumps are used in conditions where high. volumes are required and a change in flow is not a problem. As the discharge. pressure on a dynamic pump is increased, the quantity of water pumped is. reduced. One type of dynamic pump, centrifugal pumps, are the most com-. mon pump used in water systems. Dynamic pumps can be operated for short. periods of time with the discharge valve closed.
