Over the years, fluid technology has been widely used in industrial and mobile applications, such as in forestry, construction, mining and agriculture machinery. In a hydraulic pump two types of displacement pumps are used, namely, fixed and variable displacement pump. Variable displacement pumps are comparatively more expensive and complex, but they’re more efficient. Variable displacement pumps are largely used in the construction industry so as to provide better control of machinery. ... Read more

A variable displacement pump is a device used to convert mechanical energy into hydraulic energy. Displacement refers to the amount of fluid pumped per revolution of the pump’s input shaft. This can vary as per the requirement. Variable displacement pump is one of the two types of hydraulic pumps; fixed displacement pump is the other one. Fixed displacement pump has a fixed flow rate, while the flow rate of a variable displacement pump can vary even during the operation of the pump. The ... Read more
