small peristaltic pump  is required to drive pressure, and air pressure is also part of the cost, for the gas source of the diaphragm pump consumption is much more than the peristaltic pump.
Diaphragm pump is driven by air pressure, then there is pressure on the export limit, when the pressure to the limit when the pump will stop working, and the peristaltic pump is not this.
When the diaphragm pump damage can cause some of the fluid outflow, and peristaltic pump is to avoid this phenomenon.
Diaphragm pump will have a ball valve, when the system contains a back pressure to close the whole pump within the loop, otherwise there will be no way to work properly.
Diaphragm pump Although the cost of pre-investment than the peristaltic pump to be much less, but in the late use of the input is greater than the peristaltic pump, so we must understand this point.
