There are several variations of gear pumps as well as many manufacturers including Viking®. The simple gear pump shown in the illustration here, consists of two spur gears meshing together and revolving in opposite directions within a casing. Any liquid that fills the space bounded by two successive gear teeth and the case must follow along with the teeth as they revolve.
When the gear teeth mesh with the teeth of the other gear, the space between the teeth is reduced, and the entrapped liquid is forced out the pump discharge pipe. As the gears revolve and the teeth disengage, the space again opens on the suction side of the pump, trapping new quantities of liquid and carrying it around the pump case to the discharge. As liquid is carried away from the suction side, a lower pressure is created, which draws liquid in through the suction line.
There are no valves in the gear pump to cause friction losses as in the reciprocating pump. The high impeller velocities, with resultant friction losses, are not required as in the centrifugal pump. Therefore, the gear pump is well suited for handling viscous fluids such as fuel and lubricating oils.
