By Dez Duran-Lamanilao Hydraulic power units (HPUs) are a great example of applications where variable frequency drives (VFDs) are used. A VFD uses power electronics to change the frequency of input power to the motor. This allows the VFD to control motor speed. Why is VFD important? When electric motors (e.g.: induction motors, permanent magnet […]

By Dez Duran-Lamanilao Lubricants usually tend to limit the high temperature operation of ball and roller bearings, which are mostly used on centrifugal pumps; larger size pumps require different bearing specifications. Optimizing your bearing lubrication increases the efficiency of your machinery. A chamber metering valve meters grease onto the break. Source: DOPAG Below are the […]

By Dez Duran-Lamanilao It is a natural expectation for hydraulic systems to have leaks. Most systems are designed that way to allow a fluid from a higher pressurized area to travel into a lower pressurized zone. The most common purposes for such are for the lubrication, cleaning and cooling of a specific area or component. […]
