9. MAINTENANCE PROCEDURE
To facilitate maintenance it is suggested that the pump be installed in an easily accessible location.
Provide users with the necessary personal protective clothing to avoid any contact with lubricant.
Once accurately set by Dropsa, the pump does not require any maintenance.
It is recommended the use of pure lubricants and a periodical accurate cleaning of pump components.
Dismantling has to be carried out as following:
1. There is a grease pushing spring. Before dismantling the reservoir, it has to be emptied of its content.
2. Discharge the supply pressure.
3. Disconnect fitting from the pump.
4. Unscrew fixing screws and then dismantle the reservoir keeping a lot of attention to the grease pushing
spring (the spring could be charged. If so, remove the residual lubricant).
5. Remove the pump and the filters.
6. Unscrew the pump pneumatic cylinder keeping a lot of attention to the charge of the spring. After this, it
is possible to slip off pumping group components.
In this way it is possible to free every pump component, remove and clean them.
Before mounting, each component has to be washed in oil and lubricate.
The following routine operations should be performed:
