Installation of Wear Plates

Most Liquiflo wear plates are manufactured
with cut-outs or grooves to provide liquid
relief paths to reduce hydraulically induced
gear separation forces that exist during pump
operation. These forces decrease pump life
by placing significant loads on the shafts and
bearings. To be effective, the relief grooves
must face toward the gears.
NOTE: Failure to orient the wear plates
properly will reduce the operating life of
the pump.
