LIGHTNIN Series 80 Mixers - LIGHTNIN - #2

Thousands of LIGHTNIN mixers with hollow quill drives have been placed in service since we first created the design in the late 1960's to protect the gear train from severe flexures of the shaft.

The exclusive hollow quil! became part of Series 80 mixers at that time. Since then, the design has written a singular record for isolating shaft flexures and assuring long gear iife in some of the toughest applications imaginable.

Series 80 mixers are especially recommended for processes with high fluid forces on the impellers, and long impeller shaft applications.

Gearing is the same as used in our Series 70 and 90 mixers. Altogether there are tens of thou­sands of these drives at work every day around the world. It's our standard and the standard of the industry.

LIGHTNIN Series 80 mixers coverthe range from 1 Ed 200 hp. They are available in both double and triple reduction gearing, and come in a full range of standard AG MA speeds from 280 down to 16.5 rpm.

Series 80 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, mixerspeed, shaft iength and other specifications. And we guarantee performance results.

We employ a non-ioad test run on every Series 80 before it is shipped.

Hollow Quill Flex Protection.

A torsionally resilient coupling transmits power from quill to mixer shaft, while isolating gearing from shaft flexure. See the detailed drawings, and you'll see how this design protects against severe bending and shock.

Coupling Guards.

Coupling guards meet OSHA standards and protect people from moving parts.

Series 80 mechanical seals incorporate all the many significant improvements originated by LIGHTNIN over the years.

Each is tested 100% before shipment. No on-the-tank alignment, adjustment or run-in is needed. Seals are self-setting by means of springs that position the faces for equal compression.

Seal and bearing lubricants are completely separate. Each has its own inlet and outlet Ordi­nary tap water can be circulated around the seal housing for cooling.

Motor Mount,

Standard mount assures positive alignment for foot-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 mtxer 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.

Spiral Bevel Gears.

High-efficiency spiral bevel gear and pinion are quiet running They are precision generated, match lapped, individually mounted and micrometer checked.

Mechanical Seals.

The replaceable cartridge design, a LIGHTNIN original, is standard on Series 80 units. Light in weight. Easy to replace. No other design offers so much convenience. Integral stuffing box and open tank designs also available.
