LIGHTNIN 70 Series Mixers - LIGHTNIN - #2

Positive Direct Drive.

Mixer shaft slides directly into the quill, where it is rigidly coupled by a key and keyway. This design is the veteran of millions of hours of mixing.

Coupling Guards.

Coupling guards meet 0SHA standards and protect people from moving parts.

The standard Series 70 stuffing box combines a split lantern ring, split packing gland and seven rings of packing with separators.

The lantern ring distributes lubricant for better sealing performance. All fits are dowel or rabbet to assure alignment. You'll find this UGHTNIN design makes for easy repacking.

Over 30.000 UGHTNIN Series 70 mixers have been placed in service since we began making them in 1970,

Ttie same design technology is used in UGHTNIN Series 90 mixers, as well as in RMX and most CMX replacement drives for older mixers. The geartrain isthe same as in our Series 80 mixers.

That makes The Series 70 mechanical design technology the most specified, most used, most proven mixer technology in the world. It's our standard and the standard of the industry.

UGHTNIN Series 70 mixers coverthe range from 1 to 200 hp. They are available in both double and triple reduction gearing, and come in a full range of standard AGMA speeds Irom 280 down to 16.5 rpm.

Series 70 mixers offer a full choice of impellers in order to optimize your process results. Included are the high-flow A310, as well as other high performance and more traditional impellers, so we can match shear and flow to your process requirements exactly.

Together we decide what mixing should do to optimize your process. Then we recommend the impeller, mixer speed, shaft length and other specifications. And we guarantee performance results.

We employ a non-load test run on every Series 70 and Series 80 before they are shipped.

Motor Mount.

Standard mount assures positive alignment forfoot mounted motors.

Change Gears.

Easily replaceable, helical gears are standard, so speed changes are easily made to meet new process requirements. No special tools. No need to dismantle the mixer or remove it from the tank. Heavy wall pinions provide maximum protection against damage from acci­dental overloads.

Oil Dam.

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

Splash Lubrication.

Rotating gears dip into the oil sump and assure a constant flow of oil to all surfaces. No need for pumps or piping.

Mechanical Seals.

The replaceable cartridge design. aLlGHTNIN original, is standard on Series 70 units. Light in weight. Easy to replace. No other design offers so much convenience. Integral stuffing box and open tank designs also available.

Spiral Bevel Gears.

Hign-eff iciency spiral bevel gear and pinion are quiet running, they are precision generated, match lapped, individually mounted and micrometer checked to make sure.
