Maintenance
Before any maintenance operation check:
The pump is stopped and disconnected from the power supply.
There is no pressure inside the head or in the discharge pipe. It is recommended to empty
the head before opening it.
Maintenance personnel should use the appropriate means of protection for handling the
liquid being dosed.
7.5. PERIODIC MAINTENANCE
Change the oil after the first 500 hours. Next changes will be every 2000 hours (minimum once a year).
Check the piston every 3 months or 1000 hours.
Check the seals every 3 months or 1000 hours.
Check the diaphragm every 3 months or 1000 hours.
Check the bellows every 3 months or 1000 hours.
Check the condition of the suction filter once a month.
Check the condition of the valves every 3 months or 1000 hours
We recommend periodically circulating clean water through the dosing pump (coinciding for example with
the emptying of the tank), in order to remove any precipitated remains from inside the cylinder or in the
suction and discharge pipes.
In the event of using highly corrosive liquids, it is recommended to double the frequency of the
checks.
