8. Maintenance
To ensure perfect functioning, it is recommended to regularly check the gas precharge pressure and/or to control the
pointer deflection every month:
Maintenance intervals:
■
The gas precharge pressure must be checked and re-adjusted after each re-installation, or repairs. See Chapter
„Start-up“ for the precise procedure.
■
Generally, it is required to check the gas precharge pressure after each modification of the system parameters (filling
of the gas - / air cushion according to Chapter „Start-up“).
■
Check the filling device regularly for leaks.
■
Regular checks:
Yearly visual check
Every 2 years – a pressure check using water with the 1.43-fold of the nominal pressure. For this purpose,
disassemble the pulsation damper and test under pressure in a place which corresponds to the regulations
for prevention of accidents:
The operator is obliged to document these checks.
NOTE!
9. Spare- and wearing parts
Diaphragm pulsation dampers of type series 810.1 do not have replaceable wearing parts. In case of a diaphragm rupture
the complete pulsation damper is to be exchanged.
The following parts are considered as spare parts of the pulsation damper:
■
Filling- and pressure measuring device
10. Shut-down
■
Shut-down the pump/system and secure it against restarting!
■
Make sure that all pipes with pulsation dampers are pressureless!
■
Drain the pulsation dampers and the connected pipes using drain cocks!
■
Remove residues of the pumped medium from the pulsation damper by rinsing it with a compatible flushing agent!
■
Reduce gas- / air pressure (gas cushion).
■
The pulsation damper can then be removed from the pipe.
