Mixer drives
Reducers for mixers and agitators, where the output shaft carries the agitator's axial thrust, radial load and bending moment on top of torque. STM specifies reinforced output bearing arrangements and can supply a dry-well / drywell shaft to protect against product ingress. SES holds the range as an authorised STM Team distributor, covering base units A helical / O bevel-helical; output bearings Reinforced for axial, radial and bending; mounting Vertical flange (top entry) or foot; sealing Reinforced / dry-well shaft option. Executions include vertical flange-mount, reinforced-bearing output, dry-well shaft, bevel-helical right-angle. It is specified most often into tank and vessel agitators and flocculators and clarifiers. Every part is genuine STM Team through official channels, with designation, specification and options confirmed against your duty before it ships — supplied from Kolkata and our branch network, with breakdown cover that does not sit in an inbox.

Where it runs.
You will find Mixer drives in the parts of a plant where this particular duty actually occurs. In practice that means tank and vessel agitators, flocculators and clarifiers, digesters, and equally process and chemical mixers, water-treatment mixers. What links them is the duty rather than the machine name — base: Helical / bevel-helical. If your installation is not on that list it matters less than you would think: the operating condition decides the specification. Send us the load, the speed, the running temperature and the environment it runs in, and we will match it to the right execution in the STM Team range and confirm what is in stock.
Specify it against the duty.
Specification here follows the operating condition, not the catalogue. Agitator overhung/axial load on the output shaft — Mixer-duty reducer with reinforced output bearings Product-ingress risk down the shaft — Dry-well shaft with seal arrangement Vertical top-entry mount — Flange-mounted vertical bevel-helical unit Where two of those apply at once, specify for the harsher of the two — under-specifying is what puts the part back on the bench a month later. Send us the duty and we will confirm the execution.
Ordering this from SES.
Give the agitator's axial thrust, radial load and bending moment, not just torque — output-bearing life is what sets the mixer-drive selection. Send the designation off the failed part and we will confirm the STM Team equivalent and stock position.
