Vacuum Pump offers variable frequency drive.

Press Release Summary:

VmaxVFD liquid ring, oil-sealed vacuum pump produces vacuum on CNC router to hold workpieces on router tool table. Variable speed technology allows equipment to respond precisely to different loads and varies motor speed to match changing machine and usage requirements. Soft start eliminates amperage spikes, reducing energy consumption. Pump operates below 70-80 dBa, depending on size, and is available in 35-5000 cfm.

New Energy Efficient Vacuum Pump Designed to Save Money

Vmax Liquid Ring Vacuum Pump Now Available With Variable Frequency Drive.

Michigan City, Ind. - June 3, 2004 - Rick Dekker, president of Dekker Vacuum Technologies, Inc. announced today that VmaxVFD, their liquid ring oil sealed vacuum pump system, is now available with a variable frequency drive, a VFD.

The Vmax produces vacuum on a CNC router to hold work pieces on the router tool table that can be held better by vacuum than by magnetic or clamp down methods. This applies to materials such as wood, plastic, aluminum, stainless steel, brass, stone and other non-magnetic materials that require machining such as routing, engraving, milling, drilling and polishing. The advantage of using vacuum is that the work pieces to be machined can be held down without damage or distortion.

Variable speed technology allows equipment to respond more precisely to different loads and varies motor speed to match changing machine and usage requirements. The VFD controls the Vmax capacity and automatically controls the desired suction pressure whether the router is working on a large 8' x 10' sheet of wood or on smaller, intricate pieces. By operating at as low as half the horsepower, a considerable energy savings can be seen by the user, often as early as the next utility bill.

The VmaxVFD begins operation with a soft start that eliminates the amperage spikes associated with across the line starters. The utility companies bill at peak amperage usage and the number of times those peak levels are reached. The VFD significantly reduces the peak amperage numbers, which results in less overall energy costs. For shops running in a continuous, 24-hour shift setting, users will benefit from overall energy savings and longer operational life of the pump. When running constantly the machine will have less start up and stop time - the Vmax motor slows down when demand is low and the overall amperage is lowered. The VFD provides up to a 50 percent turn down in power thus equating to similar energy savings. For example, a 40 horsepower pump will run at 20 Hp with the VFD but still provide the same vacuum level required. Without the VFD, a loss of system efficiency can usually be expected for most of the operation cycle.

A common concern with CNC router users is part slippage due to insufficient flow or vacuum. The VmaxVFD addresses this concern with several additional user benefits. By providing a consistent vacuum level and operating at approximately half the horsepower, a reduction in part scrap rates and material damage can be seen by the router user. Because of the reduced energy consumption, immediate cost savings are realized. This can equal a quick payback on the system investment. Because of its conservative speed, the VmaxVFD also has a very quiet operation, below 70-80 dBA depending on the pump size. VFDs are affordable and easy to install and are one of the most cost-effective ways to maximize efficiency and reduce operating costs. The VmaxVFD is available in 35-5000 CFM.
