8.7. DISASSEMBLY AND ASSEMBLY OF THE PUMP
The assembly and disassembly of the pumps should be done by qualified personnel. Make sure that the
personnel read carefully this instruction manual and, in particular, those instructions which refer to the work they
will perform.
Incorrect assembly or disassembly may cause damage to
the pump’s operation and lead to high
repair costs and a long period of downtime.
INOXPA is not responsible for accidents or damages caused by a failure to comply with the
instructions in this manual.
Preparation
Provide for a clean working environment so some parts, including the mechanical seal, require very careful
handling and others have close tolerances.
Check that the parts which are used are not damaged during transport. When doing this, you need to inspect
the adjustment edge, the butted faces, the tight fit, burrs, etc.
After each disassembly, carefully clean the parts and check for any damage. Replace all damaged parts.
Tools
Use the proper tools for assembly and disassembly operations. Use them correctly.
Cleaning
Before disassembling the pump, clean it outside and inside.
NEVER clean the pump by hand when it is running.
