Vesconite Hilube Wear Rings Increase Pump Efficiency

Vesconite Hilube is a bearing material specially designed for long life, low maintenance bearings and bushes.

Vesconite Hilube is internally lubricated with advanced solid lubricants to give a very low friction, even without additional grease or other lubrication.

Vesconite Hilube Wear Ring Benefits:

  • No water swell
  • Superior performance
  • Extended wear life
  • Low friction
  • High load-bearing strength
  • Dimensional stability
  • Temperature limits
  • Shaft friendly
  • Chemical resistance

Vesconite Wear Rings Improve Pump Efficiency

Independent tests by a major pump manufacturer prove corrosion-free Vesconite Hilube wear rings safely allow reduced running clearances and improve pump efficiency.

Bronze casing wear rings with a clearance of 0.3 mm were tested against no-swell Vesconite Hilube at 0.1 mm.

Pump efficiency increased from 80.50 to 82.55%. Pumping head increased from 30.204 to 30.818 m.

Both these measures are important in the pump industry. In layman’s terms, pump efficiency indicates how much of the energy supplied to the pump is converted to pumping fluid.

Pump head, meanwhile, measures the pressure that the pump produces in terms of the height to which the pump can raise water.

Pump head is important where the water source is far from the pumping destination and is vital when users want to increase the pump output – think firefighters attempting to extinguish a fire from farther away.

Importantly, catastrophic failures can be avoided with Vesconite Hilube. With metal rings, if there is contact with the impeller, galling and seizures can quickly occur. But if a Vesconite Hilube wear ring contacts an impeller, it acts as a mechanical fuse and machines away safely, keeping the close clearance.

With a simple swop of the wear ring material, more efficient pumps can be achieved through closer clearances, and wear ring corrosion eliminated.
