Industrial Applications of Positive Displacement Pumps Positive displacement pumps are widely used in various industries for their ability to provide a consistent flow rate, regardless of changes in pressure or viscosity. These pumps work by trapping a fixed amount of...
What is Cavitation? Cavitation occurs when the pressure in a liquid drops below its vapor pressure, causing the liquid to form vapor bubbles. These bubbles can then collapse violently, creating shock waves that can damage the pump’s internal components....
Understanding Positive Displacement Pumps: An Overview Positive displacement pumps (PDPs) are a type of mechanical device that are essential for moving fluids in a variety of industrial applications, including on ships. These pumps work by trapping a fixed amount of...
Yes, positive displacement pumps can cavitate, although it’s less common compared to centrifugal pumps due to their different operational principles. Cavitation in positive displacement pumps usually occurs when the liquid being pumped vaporizes due to a drop in...
ic speed. Each of these parameters provides valuable information about the performance of the pump and can be used to optimize its design. 1. Volumetric Efficiency: The volumetric efficiency of a hydraulic gear pump is a measure of the actual volume of fluid displaced...
Understanding the Basics of Positive Displacement Pumps What are Positive Displacement Pumps? Positive displacement pumps, also known as PD pumps, are a category of pumps that transfer fluids by confining a fixed volume and forcing it through the system. Unlike...
