The sizing of the tank is critical to ensure pump efficiency and station functionality. To assist in fitting CDM components, we have developed the following compatibility chart as a guideline for tank selection. It is also important to consider the pump manufacturer's recommendation for the minimum distance between the pumps and between the pump(s) and the tank wall.
