Problem
Oxide dust in the environment was impregnating the sidewalls of the raw-edge V-belts, causing the belts to slip, heat up and crack. The vacuum pump was also subject to high shock loads, which polished and hardened the sides of the belts, inducing slip. Belt life was limited to 6 weeks.
Solution Description
Belt = 8 x SPC2500P Predator® V-belts
DriveR Pulley = 8/SPC400
DriveN Pulley = 8/SPC400
Idler = 8/SPC280 - inside
Benefits of Gates Product
Predator® belts are still running 12 months on – 9 times longer than the previous high capacity V-belts – due to the heavy-duty construction that reduces friction and heat build-up under shock loads at start up.
