Hydraulic Fluid Application

The cleanliness of your Hydraulic Fluid is critical to the trouble free and cost effective operation of your system. Hydraulic components are very expensive and need special consideration when selecting and filtering this fluid.

ISO 4406 code is a standard that is recognized in the industry. Certain recommended fluid cleanliness quantities are necessary to realize the best performance and cost saving operation of your hydraulic system.

Determine the required standard of filtration you require from the chart below:

Pumps <2000 PSI 2000-3000 PSI 3000+ PSI
Fixed Gear 18/15 17/15 N/A
Fixed Vane 18/15 17/14 16/13
Fixed Piston 17/15 16/14 15/13
Variable Vane 16/14 15/13 N/A
Variable Piston 16/14 15/13 14/12
Valves   2000 PSI 3000+ PSI
Directional (solenoid)   18/15 17/14
Pressure Control (modulating)   17/14 17/14
Flow Control (standard)   17/14 17/14
Check Valves   18/15 18/15
Cartridge Valves   16/13 15/12
Proportional Flow Controls   15/13 15/13
Servo Valves   14/11 13/10
Cylinders/Motors 1000 PSI 2000 PSI 3000 PSI
Vane Motors 18/15 17/14 16/13
Axial Piston Motors 17/14 16/13 15/12
Gear Motors 19/17 18/15 17/14
Radial Piston Motors 18/14 17/13 16/13
Suggested guidelines only! Precise oil sampling practices must be followed to ensure accurate tests.

Once you have determined the recommended cleanliness required, it is important to understand what the 16/14 number actually represents. (See ISO 4406 Particle count table below)

ISO 4406 establishes the amount of certain sized particles present in 1 milliliter of fluid.

The first ## refers to the count of particles > 5 micron in size.
The second ## refers to the count of particles > 15 micron in size.

The Lower you can get these two numbers; the less will be the internal damage created inside your Hydraulic System.

KLEENOIL FILTRATION will attain ISO 4406 to a standard of less than 14/9.

------Table of ISO 4406 Particle Counts------

More Than: Up To And Including: Number Scale:
5000 10000 20
2500 5000 19
1300 2500 18
640 1300 17
320 640 16
150 320 15
80 160 14
40 80 13
20 40 12
10 20 11
5 10 10
2.5 5 9

In the example: Particle count per 1 Milliliter of oil.
16/14 results in 480 average count of > 5 micron size and 120 average count of
> 15 micron size.

To ensure that you achieve the most efficient and relevant results, it is important to establish and maintain an oil analysis program.
