WR® – Wear Resistant, WR® – Wear Resistant, WR® / AR®

WR® 300

Greene Tweed WR® 300 PEEK composite bushings and wear rings increased MTBF (mean time between failure) on pumps from less than 3 months to more than 24 months.

MFG Process: Compression molding
Chopped 30% carbon fiber filled PEEK for bearings, bushings and wear rings in centrifugal pumps.
Can be sold as finished components, rods, tubes and plates of material

Features & Benefits

Mature product

Reliability: Non-Seize / Non-Gall properties –WR® components will preferentially wear if contact occurs with rotating metal parts
Efficiency: Potential for up to 50% reduction in running clearances to maximize pump performance.
High corrosion and chemical resistance.
GT can supply a full turn key solution of a metal carrier with composite insert
API610 recognized material (stationary)
WRAS approved material.

Applications

Energy market
Downstream
Centrifugal pumps in refineries
Power generation
Chemical
Fertilizer
Reverse Osmosis (RO) plants

Configurations

Overall Material Envelope:
Rods: Outer Diameter 1-2″ (25 to 51mm) , Lengths 3″ to 6″ (76 to 152mm)

Tubes:

Outer Diameter up to 6″ (152mm), Lengths = 3″ to 8″ (76 to 203mm), Cross Section = 2″ (51mm) Max
Outer Diameter 8″ to 10″ (203 to 254mm), Lengths = 3″ to 6″ (76 to 152mm), Cross Section = 2″ (51mm) Max
Outer Diameter 12″ to 14” (305 to 356mm), Lengths = 4″ (102mm), Cross Section = 2″ (51mm) Max
To obtain maximum part size, subtract the following from the values above (this is the machining allowance): Length & diameter = 0.5″ (13mm), Cross Section = 0.250″ (6mm)
