In a condition-based maintenance environment, the decision to change out a hydraulic pump or motor is usually based on remaining bearing life or deteriorating efficiency, whichever occurs first.
Hydraulic Pumps and Motors: Considering Efficiency

Oil Clotting and the Adrenaline Effect
We are all familiar with blood clotting and its role in constricting blood flow after injury. Clotting depends on the coagulation of platelets and blood cells aided by fibrin molecules to trap and bind them together. This coagulated mass effectively plugs capillaries to stop uncontrolled hemorrhaging and bleeding. Read -
Hydrodynamic Cleaning and Flushing of Turbine Oil Systems
One of the most important but underestimated factors impacting the operation of turbines (both steam and gas) and other machinery is the condition of the oil, especially its “mechanical” cleanliness (presence of solid particles). Although the need for appropriate oil care is commonly accepted among power plants with regular maintenance -
Distinguishing Regulators and Reducing Valves
We have seen a lot of confusion about pressure reducing valves and regulators in fluid power systems. This confusion is largely due to the nomenclature and partly because the schematic symbols are not always as intuitive as they could be. Read more
