Vesconite in Pumps

Vesconite has been used for decades in a wide range of specialized pump bushing applications.

The material thrives in water and exhibits excellent dimensional stability, with zero delamination. The result is low downtime and associated hassle factor.

Its friction coefficient range of 0.1 – 0.2 allows for dry starting – an issue commonly associated with high wear rates in traditional bushing materials. Corrosion of the bushing is entirely eliminated with Vesconite.

Vesconite Hilube is recommended for many pump applications.

Benefits for Pumps

Vesconite does not swell or distort in water.

Vesconite does not delaminate.

Vesconite does not corrode.

Vesconite requires no lubrication for up to 1 minute after start-up.

Vesconite is resistant to oils and fuels.

Vesconite bushings are easy to fit and remove.

Vesconite prolongs shaft life.

Material Comparison

Between the pump impeller and casing wear rings, tight clearances are required. Swelling and corrosion can be an issue with traditional materials.

This is not the case with Vesconite due to its virtually zero water absorption rate and dimensional stability, and no bimetallic corrosion.

Unlike bronze or rubber bushings, fresh and saltwater serves as an effective  lubricant for Vesconite Hilube. This makes it an ideal material for pump bowl bushings and stuffing box bushings.
