10. MAINTENANCE AND CLEANING

No maintenance is necessary during the normal operation of the pump. It may be necessary to clean some hydraulic
parts which have lost a little of their initial characteristics. Only specialised and qualified personnel, who comply with
the requirements established by the specific regulations, can disassemble the pump. We recommend disassembly by
technicians specialising in the brand. All repair and maintenance work must be performed after disconnecting the
pump from the electrical current.
11. MODIFICATIONS AND PARTS
BOMBAS SACI, S.A. shall not be responsible in the case of modifications without previous authorisation. All the parts
used for repairs must be original ones and all the accessories must be authorised by the manufacturer in order to
guarantee maximum safety of the machines and of the facilities in which they are assembled.
