LIGHTNIN 700/800 Mixers - LIGHTNIN - #2

We gave this series the capacity to drive long overhung mixer shalts without steady bearings. We gave it the stamina to withstand severe bending and high-torque loads imposed by fluid forces in the tank-Arid that's something you can't expect from the large general purpose drives not designed for mixing, which others, use.

We make shafts for 700/800 mixers larger and stronger. We size the bearings far in excess of AGMA requirements. We conduct extensive research to docu­ment the limits of shaft and impeller performance under all service conditions.

As a result, you get longer service life with less maintenance. You get our performance guarantee. You get a mixer with an enviable track record, written by the thousands of 700/800 mixers produced in our sratprbf-the-art plant at Wytheville, Virginia.

You'll find 7OGf8O0 mixers atop huge fermentation tanks in pharmaceutical production and in all manner of large-scale chemical processing. You'll also find them in the dust and rock of minerals processing, as well as in the heavy sludge of waste treatment.

Series 700/800 come in five case sizes, covering the range from 25 through 1250 hp. Both double and triple reduction drives are available, covering the full range of standard AGMA speeds from 230 rpm down to 11.4 rpm

Included are the A310 for flow-controlled applica rjons, the A320 for high viscosity requirements, the A315 for handling gas alone or gas and solids together, as well as the A6000 for applications requiring the special bene­fits of composite construction.

Every large LIGHTNIN mixer drive Is tested under load on an advanced dynamometer. Tests check gear contact patterns, noise readings, thermal data and lubrication. We welcome you to watch us tesl your mixer.

Our goal always: Deliver factory-assembled, ready-to go packaged units with interchangeable parts that will provide youlbe most efficient performance at the best possible cost.

Together, we design your rugged 700/800 mixer, selecting impeller type, shaft length and other specifica­tions to optimize process results.

Then, we guarantee your LIGHTNIN Mixer to perform¹ the job for which it is recommended.

Quiet-running Gears.

All helical gears are carburized and ground. The highly efficient spiral bevel gear and pinion are match-Sapped as a set to assure smooth, quiet operation.

Flex Protection.

Gears in all 800 series units like this one are protected from mixer shaft bending loads by the LIGHTNIN hol­low quill flex protection. Quill and mixer shaft are mounted on separate bearings. A torslonaliy resilient cou­pling transmits power from quill to mixer shaft, while isolating gearing from shaft flexure.

Beyond AGMA.

Bearings are sized lar beyond AGMA requirements to minimize mainte­nance and provide long service life.

Splash Lubrication.

On sizes up to 783/883, gears dipping in an oil sump provide a constant flaw of oil to all surfaces.

Covered For Safely.

Personnel are protected from rotat­ing parts by guards that meet OSHA requirements. All mounting flanges are designed to ASME (Jnfired Pres­sure Vessel Code

Large Series 700/800 mixers are optimally supported indepen­dently from the mixing tank. Mixers of closed tank configuration can be mounted on their own beams or on the plant floor above the tank, Either way, only a separate seal or stuffing box need be mounted on the tank and supported by it.

Mounling on upper lloor. Note how J hydraulic lilts can simplify servicing

Oil Dam.

Leakage down the mixer shaft is positively prevented by an oil dam around the quill shaft.

Rugged Motor Mount.

A heavy-duty channel base is the standard motor mount for Series 700/800.
