VKGH double cylinder high pressure filter series

The dual-cylinder filter element is mainly suitable for the filtration of oil in the hydraulic transmission system. It is used to remove particles and rubber debris in the hydraulic transmission system, to ensure the cleanliness of the lubricating oil, and to make the hydraulic transmission system operate normally.

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 150L/min, precision 10u, 46# hydraulic oil

Selection VKGH330

ΔP shell=0.84bar, ΔP filter element=0.46×(46mm²/S÷30mm²/S)=0.7

ΔP total==0.84+0.7=1.54bar
