Aqua Transmission Drives
Geared drives built for aquaculture aeration equipment, where the unit sits over brackish water and runs long hours in high humidity. Construction and sealing are aimed at corrosion and water ingress rather than heavy shock. SES holds the range as an authorised JK Fenner distributor, covering gear type Worm and helical reduction to suit paddle speeds; output speed Low rpm suited to paddle wheel aeration; protection Corrosion resistant finish and sealed shaft ends; mounting Float and frame mounting arrangements. Executions include paddle wheel aerator drives, aspirator aerator drives, long arm aerator drives, pond circulator drives. It is specified most often into paddle wheel aerators in shrimp and fish ponds and aspirator and injector aerators. Every part is genuine JK Fenner 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 Aqua Transmission Drives in the parts of a plant where this particular duty actually occurs. In practice that means paddle wheel aerators in shrimp and fish ponds, aspirator and injector aerators, pond water circulation units, and equally feed distribution machinery on farm sites, floating aerator platforms on large water bodies. What links them is the duty rather than the machine name — duty: Continuous aeration in ponds. 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 JK Fenner range and confirm what is in stock.
Specify it against the duty.
Specification here follows the operating condition, not the catalogue. Unit sits directly over saline water with constant splash — Protected external finish and shielded shaft seals. Bare cast iron and standard hardware bleed rust into the pond and the fasteners seize within a season. Aerator runs through the night with no attendance — A drive rated for continuous duty at that output speed, not an intermittent rating. Ponds lose oxygen fast when a drive stops, and unattended hours are exactly when it happens. Paddle wheel picks up weed or debris and stalls — Include an overload path such as a shear device or motor protection set to the actual stall current. Otherwise the gearbox takes the whole locked-rotor torque. 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.
Rinse the drive housing with fresh water at the end of each crop cycle before the unit goes into storage. Dried salt on a gearbox casing pulls moisture out of the air and corrodes it faster in the shed than it did in the pond.
