Maintenance/Disassembly

Pumps are subject to wear. If the pump is blocked or grinding noises are audible, check
the pump and replace it if necessary. Procedure:
When replacing non-LOWARA motors, use the additionally included flat seal. The groove
for holding the flat seal in non-LOWARA pump housings has an additional ridge that can
cause leakage when used with an O-ring seal.
