Introduction of 3BPF** 

3BPF** series external Gear Pumps have a floating busing with automatic axial clearance compensation. These pumps have been around the longest and are also the simplest. They employ two parallel gears mounted on shafts and can have single or double rows of teeth. The simplest version has straight cut `spur` gears of involute form but `herring bone` and also `helical form` teeth are also available. These latter designs are quieter and slightly more efficient than simple spur teeth but also more difficult to manufacture. All gear pumps rely in fine clearances especially when handling thin fluids to prevent internal leakage around the gears also known as `slip` For this reason gear pumps become less efficient with thin fluids especially when differential pressures are high.
