Service Kits; Contaminated Pumps - Grundfos AP80 Vortex Montage- Und Betriebsanleitung

• Pump parts
Check the impeller, pump housing, etc. for possible wear. Re-
place defective parts.
• Ball bearings
Check the shaft for noisy or heavy operation (turn the shaft by
hand). Replace defective ball bearings.
A general overhaul of the pump is usually required in case of
defective ball bearings or poor motor function. This work must
be carried out by an authorized GRUNDFOS service work-
shop.
