Almost every cleaning system incorporates at least one pump. Understanding how that pump works and how to treat it with the gentle, loving care it deserves is critical to the successful operation and maintenance of a cleaning system. Pumps are, in general, devices which impart added pressure to a flow of liquid. Although there are a number of different …
There was an error in the chart showing cavitation bubble size vs. ultrasonic frequency in the blog published on December 14, 2011. The bubble size was incorrect by an order of magnitude. The correction can be seen at Ultrasonics – Number and Size of Cavitation Bubbles I apologize for the error and any mis-understandings it …
Today’s ultrasonic transducers utilize either the piezoelectric or magnetostrictive effect of materials to produce ultrasonic waves in liquids. This blog will concentrate on the magnetostrictive ultrasonic transducer. Magnetostrictive Transducers – Magnetostrictive ultrasonic transducers utilize the principle of magnetostriction exhibited by “ferromagnetic” materials which include iron, nickel and cobalt as well as many alloys of these …

Before we get into quantifying the particles we have harvested in the last few blogs, I would like to take a minute or two to talk about the specifications that define and govern the evaluation process. In upcoming blogs we will talk about the quantification of particles in general terms. In real life, there is …
The most challenging applications for filtration often involve either very small particles or huge volumes of particles – sometimes both. The filtration of buffing and lapping compound residues from solution is a good example of such an application. There are a number of “specialty” filters available which may answer the needs of the more challenging applications. …
Have a Happy and SAFE Fourth of July!
