Benefits of Gates Product

The Poly Chain® GT Carbon™ belt drive ran for 24 months. Maintenance and downtime have been eliminated. The new drive weighs 59% less resulting in a much lower overhung load on shafts. An efficiency increase and power consumption reduction of 5% was achieved, which translates to $2000 per year savings. This site has 50 Warman pump drives so overall savings potential is significant. Drive reduced in width from 213 to 106mm.
