Vesconite wear rings offer pump operating advantage
Vesconite Bearings’ casing wear rings are proving
so popular that they are currently the company’s
most important wear component for the pump
industry.
The wear rings are used to restrict the pressure
leakage of the fluid between the inlet of the impeller
and the pump casing in centrifugal pumps.
The wear rings are made from the thermoplastic
Vesconite Hilube, which is a low-friction, wear-
resistant polymer that replaces traditional metals
such as bronze and stainless steel as well as other
thermopolymers.
Here are the benefits:
• They replace metal components that require
large running clearances to avoid metal-on-
metal contact. Metal-on-metal can result in
galling and unwanted pump vibration, as well
as severe damage to the pump;
• They improve efficiency since tighter running
clearances can be applied;
• They do not require pump redesigns, since they
can fit into the same housings used by metal
wear rings and, because they are press fitted,
do not require mechanical fitment or glue;
• They can be easily machined from a variety
of tube stock or they can be machined for
use using Vesconite Bearings’ machining
capability;
The casing wear rings.
• They are impervious to salt-water corrosion and
thus are ideal for sea water and reverse osmosis
pumps where galvanic corrosion may destroy
stainless steel wear rings;
• They resist cavitation, a problem often
encountered with metal wear rings; and
• Vesconite Hilube is approved, including
by NSF61 and WRAS, for drinking water
applications. PA
