Pump efficiencies improve with bushings and wear rings

Several pump manufacturers have discovered that a combination of Vesconite Hilube bushings and wear rings can improve pump efficiencies more than using either the bushings or wear rings in isolation.

“One client introduced Vesconite Hilube bushings to their multi-stage pumps, but still had a stainless steel wear ring that needed bigger running clearances,” explains pump technical advisor at Vesconite, Phillip de Villiers.

Vesconite Bearings pump technical advisor, Phillip de Villiers, notes that many pump manufacturers are switching to Vesconite Hilube thermopolymer wear rings and bushings to achieve better efficiencies.

“The company has since switched to Vesconite Hilube wear rings, thereby reducing running clearances and improving efficiencies.”

Efficiencies are improved if thermopolymer wear rings and bushings are used together and their running clearances are matched to each other. This results in reduced leakage as well as electricity savings.

An additional benefit is that metal-on-metal wear is eliminated since polymer components that touch the metal are worn away themselves rather than having the metal wear away or become damaged.

“Every pump manufacturer is trying to achieve better efficiencies,” says De Villiers.

“This is why many are seriously considering using Vesconite Hilube bushings or wear rings and, increasingly, both in their multi-stage pumps.”
