Hydraulic External Gear Pumps 

Introduction of 2.5APF **  2.5APF** series external gear pumps have a floating busing with automatic axial clearance compensation. Gear Pumps are a type of Rotary Positive Displacement Pump.They consist of at least two separate and rotating gears with intermeshing teeth. As these meshed teeth separate, they create a partial vacuum which is filled by the fluid being pumped. As the gears then continue to rotate the fluid becomes trapped and is carried around the casing to the discharge side of the pump. Here as the gear teeth begin to re-mesh the fluid is ejected creating a pumping action. There are a number of different Gear Pump designs but ultimately they all employ this same pumping principle. Note that contrary to common belief, pumps do not suck! Instead they create a partial vacuum within them which becomes filled or partially by the fluid which must be at a higher pressure for it to work. Specifications Specifications…
