Slide 3. The Functions of the Diaphragm Pump The overall function of the diaphragm pump is to “move fluid from a lower potential energy to a higher potential energy” Sub functions of this device are to Propel a fluid (sludge) Increase the relative pressure of a fluid Decrease the relative pressure of the fluid Quietly propel a fluid Efficiently propel a fluid Propel a fluid with minimal shear Propel a fluid containing large particles The “Macro” Device Diaphragm  pump 400L/min 1 Bar to 8.5 Bar 1 Bar to 0.5 Bar less than 90 Db not less than 20% 3 < mm Note that 1 bar = 1 x 10 5 Pa or N/m 2 A diaphragm pump is a positive displacement pump
