Viking

Viking Pump, Inc. has been a gear pump industry leader and innovator since its founding in 1911. They continue to build on their ever-growing experience to deliver innovative pumping solutions (including custom designs) to thousands of customers who use millions of Viking pumps in some of the world's toughest applications. The Viking range of gear pumps includes both internal gear pumps and external gear pumps. The internal gear pumping principle was invented by one of the founders of Viking Pump. It uses two rotating gears which un-mesh at the suction side of the pump to create a vacuum which pulls fluid into the pump. The spaces between the gear teeth transport the fluid on either side of a crescent to the discharge side, and then the gears re-mesh to discharge the fluid. The external gear pumping principle uses two rotating gears which unmesh at the suction side of the pump to create a vacuum which pulls fluid into the pump. The spaces between the gear teeth transport the fluid along the outer perimeter of the housing to the discharge side, and then the gears re-mesh at the center to discharge the fluid. The gears are supported by bearings on both sides, which allows high discharge pressure capabilities. Seal-less magnetic drive pump, versions are also available across some of the ranges of gear pumps.
