Pump ED 101

In fact, one small centrifugal grinder pump will produce the same fluid velocity as five small positive displacement pumps. If we assume a minimum cleansing velocity of 2 feet per second, a single centrifugal grinder will maintain a 2.5” force main. In a positive displacement system, four pumps are required. For a 4”

Additionally, the fluid velocity must be between 3 to 9 ft/sec. This last constraint actually lends itself quite well to wastewater lift design because if the wastewater velocity is below 3 ft/sec., there will not be enough energy to scour the pipe of solids. Conversely, water flowing above 9 ft/sec. can scour the pipe material and damage the
