diaphragm rupture, we recommend you drain the pump crankcase of the mixed oil and
pumped liquid and then fill it with oil or diesel to prevent the formation of rust.
• The following are frequently the causes of diaphragm rupture:
- bottlenecks in the intake circuit (inadequate hose section, very dirty filter, very dense
liquid being pumped, etc)
- the use of very aggressive chemicals
6.3 SPECIAL MAINTENANCE
CAUTION
• Only Skilled Technicians are authorised to carry out special maintenance.
• Dispose of waste oil correctly; do not dump it in the environment
Follow the instructions in the table below for special maintenance.
For appliances fitted with a combustion engine, remember to follow the instructions for special
maintenance in the engine’s operating and maintenance instructions
(*) Check more frequently if liquids are used with suspended abrasive particles.
(**) Oil must also be changed when diaphragms are replaced.

(****) We recommend replacing diaphragms regardless of their condition if particularly
aggressive chemicals are used

of particularly heavy use.
