Apart from the ingress of debris, the greatest danger to any design of a pump is cavitation. The phenomenon can be found in centrifugal (i.e. impeller) or positive displacement (i.e. gear, gerotor or vane) pumps, in both oil and coolant applications. Excessive cavitation can lead to erosion damage. It is important to understand how cavitation occurs as there are some misconceptions and confusion on this topic.
We started with two questions: Are automotive companies researching and testing additive manufacturing? If so, then what steps are they taking to implement this into their projects going forward? UW's Lisa Brock informed of the several industry-leading companies that are currently conducting case studies and even implementing additive manufacturing to their portfolio.
