Vesconite announces successful wear ring testing
Independent tests have shown that corrosion-free Vesconite Hilube wear rings safely allow reduced running clearances and improve pump efficiency.

Independent tests by a major pump manufacturer have shown that 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 and results showed that pump efficiency increased from 80.50 to 82.55%, while pumping head increased from 30.204 to 30.818 m, both important measures within the industry.

Pump efficiency indicates how much of the energy supplied to the pump is converted to pumping fluid, while pump head measures the pressure that the pump produces in terms of the height to which the pump can raise water. Head is important where the water source is far from the pumping destination and is vital when users want to increase the pump output.

The company says that catastrophic failures can be avoided with Vesconite Hilube. If metal rings touch the impeller, galling and seizures can quickly occur. However, if this happens with a Vesconite Hilube wear ring, it acts as a mechanical fuse and machines away safely, keeping the close clearance.
