Guaranteed Performance: 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 that are backed up by our standard warranty.

Specifications

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.

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 CE and OSHA standards and protect people from moving parts.

Spiral Bevel Gears
High-efficiency spiral bevel gear and pinion are quiet running. They are precision generated, match lapped, individually mounted and micrometer checked to make sure.

Motor Mount
Standard mounting assures positive alignment for flange or foot mounted motors. A machine earth grounding point is provided as standard.

Pedestal Cover
Personnel are protected from rotating parts by a guard design that meets CE and OSHA requirements.

Oil Dam
Leakage down the mixer shaft is avoided 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.

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

MECHANICAL SEALS
The replaceable cartridge design, a Lightnin original, is standard on Series 70 units. Light in weight. Easy to replace. Our design offers unrivaled convenience. Integral stuffing box and open tank designs also available. Each Lightnin Cartridge seal is still tested 100% prior to shipment and offers the very best in reliability while our other seal selection meet performance. Additionally we continue to supply low and high pressure stuffing boxes. All fits are dowel or rabbet to assure alignment. You’ll find this Lightnin design makes for easy repacking.
