Determination of filter specifications
Shell pressure drop flow curve
VKCH30
VKCH60/110
Filter element pressure drop curve
The pressure drop characteristic curve of the filter element is suitable for mineral oil with a kinematic viscosity of 30mm²/s, and the pressure drop changes in proportion to the viscosity.
Selection example
formula
ΔP total = ΔP shell + ΔP filter element × (viscosity mm²/S÷30mm²/S)
For example:
Flow 40L/min, accuracy 10u, 46# hydraulic oil
Selection VKCH660
ΔP shell=2.0bar, ΔP filter element=0.35×(46mm²/S÷30mm²/S)=0.54
ΔP total==2.0+0.54=2.54bar
