6.1 Periodic maintenance
The APP pump is designed so that lubrication
follows from the water itself and there is thus no
oil in the pump.
The pump requires no periodic replacements of
seals and valve parts.
6.2 Repair
In case of irregular function in the pump, please
contact the Danfoss Sales Organisation.
