• By drawing up a maintenance plan, costly repairs can be avoided
with a minimum of maintenance expense and fault-free pump
operation obtained. Salmson Service is available for all initial
commissioning and maintenance work.
• A record is to be kept of any maintenance.
Before carrying out any maintenance work, switch off the
pump and ensure that it cannot be switched on again in an
unauthorised manner. Never carry out work on a running
pump.
7.1 Decommissioning
After long periods out of use we recommend checking the pump for
impurities and if necessary cleaning it.
7.2 Disassembly and assembly
- Disassembly and assembly should only be carried out by qualified
personnel !
- Disconnect power supply !
- Close gate valve (inlet and pressure piping).
- Drain collecting vessel (e.g. using manual diaphragm pump).
- Then screw on inspection cover for cleaning.
If a used unit or parts thereof are to be returned for repairs,
they must be drained and cleaned prior to transport for
reasons of hygiene. In addition, all parts which may be
touched are to be disinfected (spray disinfection). The parts must be
tightly sealed in tearproof, sufficiently large plastic bags and
packed in leakproof packaging. They must be returned
