Aeration vs Cavitation

Aeration vs Cavitation

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.

Exploring Additive Manufacturing

Exploring Additive Manufacturing

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.

Methods of Introducing Air into Oil

Methods of Introducing Air into Oil

There are a number of ways to introduce air into the oil to obtain a certain level of aeration. There are two predominant methods for achieving oil aeration: suction port t-fitting and direct injection.

Pump Testing Methodologies

Pump Testing Methodologies

Whether developing a new hydraulic pump design that has to closely match predefined specifications, or verifying the functionality of a production unit, an accurate and reliable test system is needed to confirm the functional parameters of those pumps.
