Hydrovac ejector

RULA design, manufacture and supply greas lubricators on belt conveyors for a wide range of Bulk Materials handling applications


The RULA HydroVac and Jet Pumps are used to convey and mix various slurry products. The conveying is initiated by a high speed/pressure water stream that creates a vacuum below a hopper. The primary and secondary materials then mix and is conveyed together via pipelines and slurries.

The flow of the material to be transported may be controlled either specifically with a manual or automatic valve or relatively controlled using the inherent design of the system depending on the user requirements.


May either be multi nozzle or single in-line systems transporting various powdery or granular material in slurry form.
