Gear Pump Selection Filters

When choosing oil pump gear asked the selection filter, choose how to filter, gear pumps to be implemented by active and passive gear mutual occlusion operation, so when particles larger than 40um on gear pump life will be affected, plus filter is also necessary. Particle size in the lO/um effects of pollutants on gear oil pump not too obvious and greater than 10 TEM, particularly in more than 40/UM the use of gear pump life expectancy significantly, hydraulic oil solid contaminant particles in relative motion of the parts within the pump surface can be easily increased. For this you need to install filters to reduce oil pollution. Choose the choice of filter is filtering accuracy.
