Hydraulic pump efficiency comprises volumetric and mechanical efficiency. Volumetric efficiency compares actual to theoretical flow rate, primarily affected by internal leakage. Mechanical efficiency measures how much input power converts to hydraulic power, mainly influenced by frictional losses. Combined total efficiency can exceed 90% in quality piston pumps.
Though less visible than displacement or pressure, efficiency significantly impacts excavator fuel consumption. Efficient hydraulic pumps reduce energy loss, lowering engine load and saving fuel. This explains why high-end excavators invest more in high-efficiency piston pumps.
