Buried Service Gearbox
Acrogears buried service gearboxes are a perfect solution for buried butterfly valves.
Our standard Acrogears gearbox is subject to a number of additional features that make is suitable for permanent buried applications, generally in compacted dirt.
The existing gearbox has significant sealing as standard, O-rings on both ends of the drive sleeve, sealed input shaft bearing, lip seal on the input shaft, seals on the end-of-travel end stop adjustments, fully gasketed surfaces and an O-ring seal at the top of the drive sleeve cover.
The gearbox then receives 316SS fixing hardware with thread sealer to all bolts, indicator is replaced with a sealed static cover, grease is replaced with waterproof marine grade grease and finished with significant protective coatings.
We also incorporate an input adaptor to allow a sealed torque tube to be adapted minimising disturbance to the surrounding compacted dirt.
