SMALLER, FASTER, EASIER PUMPING WITH VIKING MOTOR SPEED

Posted: Thursday 6th October 2016

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, available from MICHAEL SMITH ENGINEERS 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 name Motor Speed emphasises the ability of these pumps to be driven by standard electric motors at either 720, 960 or 1450 rpm, without the need for a reduction gearbox. Whilst the term motor speed is a generalisation and depends on the actual duty, for many applications it will enable smaller pumps to be run faster providing higher flows. The range includes models which provide flows up to 88 m3/h at standard motor speeds, or 132 m3/h with speed reducers or gearboxes.

Viking has unrivalled experience in positive displacement pumping and application expertise and this, combined with advances in the science of flow, has contributed to the innovative design of the Motor Speed pump head. For example, the pump head now 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 optimise flow paths.

The pump rotor's profile has also been increased and, on larger models, the standard idler material is hardened steel case hardened to 39 Rockwell C to reduce the effects of cavitation. The result of all these design improvements is that the pumps can be operated at higher speeds than before so you get a greater flow from a smaller pump than previously. Other features of the new Motor Speed Series include a pressure lubricated idler pin and bushing to enhance the pin and bushing life, sealed, anti-friction bearings eliminating the need for re-lubrication, a behind the rotor seal which means the drive shaft and bearings are not exposed to the pumped media and a threaded one-piece bearing housing which allows for easy end clearance adjustment.

Viking Motor Speed pumps are available in a close-coupled and long-coupled drive options for motor speed operation and with gearboxes, or speed reducers for reduced speed operation.

In common with the general characteristics of Viking Internal Gear pumps, the new Motor Speed pumps are designed to meet the demands of heavy-duty, industrial pumping applications, even in the most challenging environments. Typical applications will be transferring refined fuels such as diesel and biofuels, also crude oil, edible oils, lubrication and hydraulic oils as well as chemicals including solvents, glycols and refrigerants.
