Why repair your Series 70 Mixer Drive with us
Real numbers before teardown
Most shops quote only after your unit is in pieces on their bench. We publish the whole market — new, used, scrap, competitor repair — up front, so you negotiate from strength.
Cheaper and faster
Our network rate beats standard shop pricing by roughly 18–25% on the Series 70 Mixer Drive, with turnaround 2–3 days shorter — and 24–72 hour emergency rush when the line is down.
Two-way market maker
If repair isn't the smart move we say so, buy your unit for cash, and can supply a tested used replacement. No other gear shop gives you all three exits.
20+ years of industrial iron
Industrial Surplus World has bought, sold, and rebuilt Lightnin equipment for decades — chemical mixing drives are daily work, not an experiment.
About the Lightnin Series 70 Mixer Drive
The Lightnin Series 70 Mixer Drive is a turbine agitator gear drive from the Series 10, 70, 80 mixer drives line, rated 1–250 hp across ratios of case sizes 7-1 to 7-10, and most commonly found on chemical mixing. Lightnin (SPX Flow) mixer drives are the chemical-plant standard; Series 10/70/80 gearboxes take constant thrust loads and need specialist rebuilds.
When a Series 70 Mixer Drive fails, the real decision is economic: a new unit lists at $9,500–$32,000 with a 16–30 week factory queue, a tested used unit trades at $3,800–$23,000 when you can find one, and a standard shop rebuild runs $4,400–$19,200 over 10–15 business days. Our in-house network rate of $3,400–$15,700 in 8–12 business days beats all of those paths on total cost of downtime — and if the unit is beyond economic repair, its scrap weight alone is worth $76–$187, while we'll pay $460–$5,500 for the core as-is.
Typical failure modes on this family are bearing wear, shaft-seal leakage, and tooth-surface distress from degraded or contaminated oil. A correct rebuild means full teardown, hot-tank cleaning, magnetic-particle inspection of all gearing, verification of bearing-bore tolerances, all-new bearings, seals, shims and gaskets, reassembly to factory clearances, and a loaded run-test with warranty up to 24 months. Done right, it restores full service life at a fraction of replacement cost.
