to prevent static sparking. Fire or explosion can result, 
especially when handling flammable liquids. The 
pump, piping, valves, containers or other 
miscellaneous equipment must be grounded. 
WARNING!
When used for toxic or aggressive fluids, the pump 
should always be flushed clean prior to disassembly. 
User must ensure chemical compatibility, and any 
pressure / temperature limits are not exceeded. These 
instructions include all the information for relevant 
diaphragm temperature limits. Pump temperature range can also be found on 
data-plate attached to the pump. 
If pump is not used for more than 5 days, care must be taken when restarting. 
If in any doubt, remove pump from line and flush with a suitable cleaner. 
Solidified deposits within the pump may cause damage to the diaphragms. 
WARNING!
Before pump operation, inspect all gasketed fasteners for 
looseness caused by gasket creep. Re-torque loose 
fasteners to prevent leakage. Follow recommended 
torques stated in this manual. In cases of excess vibra-
tion, Blagdon recommend fitting a Pulsation Dampener to 
remove effects of pulse actions from pump operation. Flexible connections 
can be used, but must be kept to a minimum length necessary to avoid sharp 
flexing or straining movements. 
CAUTION!
In the event of diaphragm rupture, pumped material may 
enter the air end of the pump, and be discharged into 
the atmosphere. If pumping a product which is hazard-
ous or toxic, the air exhaust must be piped to an appro-
priate area for safe disposition.
WARNING!
Grounding the pump :-
All models are certified as shown on page 1 of this manual. 
Maximum temperature of fluid to be handled must be specified at time 
of order. Pump must be marked with this information. For grounding 
details see below. 
This unit is supplied with a natural earth ground cable. This cable is 2 
meters in length and permanently connected through a stud at one 
end to the pump centre casting. The other end is free to connect to 
the nearest available suitable point to provide a natural earth ground. 
This must be done to reduce the risk of electro-static sparking. 
 
Refer to table on Page 8 for details and relevant Part Numbers.
