The environmentally sensitive hydro-power industry requires components that last longer in the absence of contaminating lubricants. These two factors alone make Vesconite Hilube the ideal bushing and bearing material in these demanding conditions. Water serves as a natural lubricant for Vesconite Hilube, which in turn, ensures a clean and grease-free operating environment. Unlike many traditional materials, Vesconite Hilube does not swell in water, nor does it distort or creep under load within wet hydro-power settings. Therefore not only does Vesconite last longer, so do its metal counterparts.

Common Hydro Applications


  • Vesconite Hilube does not require external lubrication, avoiding water contamination.
  • Vesconite Hilube can run dry ‚Äď important for pump start-up and priming.
  • Water is a natural lubricant for Vesconite Hilube.
  • Vesconite Hilube does not swell in water, reducing risk of seizure and allowing for close tolerances.
  • Vesconite Hilube has a low friction coefficient, eliminating vibration and the stick-slip effect.
  • Vesconite Hilube‚Äôs unique combination of properties ensures long life and little downtime.


Traditional bushings require costly maintenance downtime time on pump turbines.

Metal or rubber bushes can degrade quickly in dirty and abrasive environments
e.g trash rake pivot points.

The low friction of Vesconite Hilube avoids stick slip on pressure relief valve guides.

Wicket gate bushing lubrication is often difficult due to the micro-oscillating movements associated with this application.
Vesconite Hilube’s self-lubricating properties avoids this entirely.
