A new and innovative internal gear pump which can be driven by standard electric motors, without the need for a gearbox, is the latest addition to the established range of Viking pumps. The Viking Motor Speed pump (photo), available from this company, is designed to run at higher speeds and deliver increased flows, resulting in a more cost-effective pumping solution requiring less space and at reduced cost. The pumps can be driven by standard electric motors at either 720, 960 or 1,450 rpm, without the need for a reduction gearbox. For many applications, smaller pumps can be run faster, thereby providing higher flows. The range includes models that deliver flowrates up to 88 m³/h at standard motor speeds, or 132 m³/h with speed reducers or gearboxes. Other features include a pump head that incorporates idler and rotor speed grooves to improve axial feed, a liquid directing step to reduce turbulence, a modified crescent to boost radial feed and improved port geometry to optimize flow paths. — Michael Smith
