Hydraulic Fluid for Hydraulic System Pumps 15## November 2019

Hydraulic systems are used for a variety of purposes, from simple manufacturing processes to fully integrated systems in the paper and steel industries. All systems, regardless of size or complexity, have several key components, including:

  • Valves
  • Reservoirs
  • Actuators
  • Pumps

Each of these components serves a specific purpose and require that the hydraulic fluid used in the circuit is a suitable lubricant as well as medium of power transmission. Each type of pump will give optimum performance using different oil specifications and viscosities. It is therefore important to identify the type of pump used, such as:

  • Gear Pumps
  • Vane Pumps
  • Piston Pumps

Once the pump has been identified, you need to select the correct hydraulic fluid. Two important aspects to choosing the correct hydraulic fluid or oil are the fluid/oil type and the viscosity grade. These factors are normally determined by the operating pressure of the system, the type of pump being used, and the operating environment.

Lastly, you need to decide whether you want to use synthetic, petroleum-based, water-based or mineral-based fluids. Each has its own benefits and specific purposes. For instance, water-based fluids are well-suited in environments where fire-resistance is important.
