Avoid electrostatic charge: Do not rub non-metallic surfaces with a dry cloth for cleaning etc; ensure the
cloth is damp.
2.8 Preventing leakage
The pump must only be used to handle liquids for which it has been approved to have the correct
corrosion resistance.
Avoid entrapment of liquid in the pump and associated piping due to closing of suction and discharge
valves, which could cause dangerous excessive pressures to occur if there is heat input to the liquid.
This can occur particularly if the pump is stationary.
Bursting of liquid containing parts due to freezing, must be avoided by draining or protecting the pump
and ancillary systems.
If leakage of liquid to atmosphere can result in a hazard, the installation of a liquid detection device is
recommended.
2.9 Maintenance to the double diaphragm pump to avoid the hazard
CORRECT MAINTENANCE IS REQUIRED TO AVOID POTENTIAL HAZARDS WHICH GIVE A
RISK OF EXPLOSION
The responsibility for compliance with maintenance instructions is with the plant operator.
To avoid potential explosive hazards during maintenance, the tools, cleaning and painting materials used
must not give rise to sparking or adversely affect the ambient conditions. Where there is a risk from such
tools or materials, maintenance must be conducted in a safe area.
It is recommended that a maintenance plan and schedule is adopted, in line with the user instructions
provided, to include the following:-
a Any auxiliary systems installed must be monitored, if necessary, to ensure they function correctly.
Particular care must be paid to checking the Sentinel diaphragm protection system vacuum on a
daily basis.
b Check for any leaks from gaskets and seals. The condition of the divider seal must be checked
regularly to ensure correct functioning.
c Check that the duty condition is in the safe operating range for the pump.
d Check that dirt and dust is removed from operational areas of the pump.
e Check the free operation of the air valve spool.
f Renew the thrust tube bearings every 1000 running hours.
g Inspect the diaphragms at least every 1000 running hours and renew if any sign of damage is apparent.
