Why does my Westfalia Water Filtration Systems bowl not come up to rated speed?
- J
  Jennifer RiosAug 5, 2025
  Several factors can cause the bowl of your Westfalia Water Filtration System to not reach its rated speed. It could be due to the brake being applied—release it by turning the handle clockwise. Alternatively, oil on the spindle might be causing the drive belt to slip; clean the belt contact surface and consider replacing the drive belt. Other potential causes include an incorrectly connected motor (check the connection), an insufficient number of clutch shoes (increase their number), a stretched drive belt (replace it), an incorrectly fitted drive belt (check its position), or liquid/dirt accumulation in the upper frame section (check the operating water discharge and clean the frame).

What to do if my Westfalia Water Filtration Systems centrifuge has an uneven run?
- G
  George GonzalezAug 15, 2025
  An uneven run in your Westfalia Water Filtration Systems centrifuge can stem from several causes. The bowl might be out of balance due to uneven dirt deposits, incorrect assembly, slack disk stack tension, or damaged bowl parts. In such cases, shut down the separator, apply the brake, and close the product feed and discharge. If the bowl leaks, fully open the water supply and clean the bowl. Ensure proper assembly and check the bowl lock ring's tightness. Also, worn ball bearings can cause this issue; replace them, using only specified bearings. Do not attempt to weld or solder the bowl!

Why does the bowl speed drop during operation of Westfalia Water Filtration Systems?
- R
  Ronnie HunterAug 25, 2025
  If the bowl speed drops during the operation of your Westfalia Water Filtration Systems, it could be because the friction surfaces of the clutch shoes are oily. If so, wipe the friction surfaces dry, but do not use benzene, tri-chlorethylene, or any other solvent. Another possible reason is that the motor speed is dropping, so you should check the motor and line voltage.
