tractor triple gear pump

Introduction of Multiple 3PF**

These series external gear pumps have a floating busing with automatic axial clearance compensation. The action makes gear pumps self-priming. Subject to physical constraints such as motor power, casing strength, shaft sealing and to hydraulic factors such as volumetric efficiency the discharge pressure of a gear pump can be very high. Centrifugal pumps have a Best Efficiency Point (BEP) which can be critical. This does not apply to gear pumps. Gear pumps is low versus centrifugal pump making them very useful where there is little net positive suction head available.
