Relationship of Viscosity to Pump Efficiency

Hydraulic pumps convert mechanical energy from electric motors or internal combustion engines into fluid flow; however, some energy is always lost during this process. Mechanical losses occur due to fluid friction at higher viscosities, while volumetric losses due to internal fluid leakage occur at lower viscosities. Each hydraulic pump has an optimum operating viscosity range that will provide maximum pump efficiency by keeping mechanical and volumetric losses to a minimum.

Relationship of Viscosity to Pump Efficiency

A hydraulic pump manufacturer states that an operating fluid viscosity of 20-40 cSt provides optimal energy efficiency in a piston pump. They also state that the fluid viscosity at cold startup should not exceed 1,000 cSt, or fall below 14 cSt at any time during operation. The high viscosity index of LE’s Equipower Ultra HVI Hydraulic Oil enables the f luid to remain within the optimal operating viscosity range throughout a wider operating temperature range than non-HVI fluids. Ultimately, this helps increase the bottom line by increasing pump efficiency in the form of reduced mechanical and volumetric losses. Less energy consumption also yields a smaller carbon footprint by reducing greenhouse gas emissions.
