Blagdon Pump B50 Metallic - Manual (Page 8)

HG-CF-1099 Rev. S – 01.05.14 Page 8
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 vibration, 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!
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!
Important Warnings and Safety Information
This pump is pressurized internally with air pressure during operation. Always make certain that all bolting is in good condition and that
all of the correct bolting is reinstalled during assembly. End-user must ensure correct fitting of Inlet / Outlet connections. Crossed
threads or over tightening of connections will result in leaks. Quick action/release connections are not recommended. If their use is
unavoidable, the levers must be locked to avoid them being forced apart in a hazardous manner.
WARNING!
Before doing any maintenance on the pump, be certain all pressure is completely vented from the pump, suction, discharge, piping, and
all other openings and connections. Be certain the air supply is locked out or made non-operational, so that it cannot be started while
work is being done on the pump. Be certain that approved eye protection and protective clothing are worn at all times in the vicinity of
the pump. Failure to follow these recommendations may result in serious injury or death.
WARNING!
Before maintenance or repair, shut off the compressed air line, bleed the pressure, and disconnect the air line from the pump. The dis-
charge line may be pressurized and must be bled of its pressure. End-user must ensure correct regulation of air supply pressure, as any
increase in air pressure results in a similar increase in product pressure if stalled-out.
WARNING!
Airborne particles and loud noise hazards. Wear ear and eye protection.
WARNING!
Take action 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. Refer to exhaust safety instructions on page 9.
WARNING!
Read these safety warnings and instructions in this manual completely, before installation and start-up of the pump. It
is the responsibility of the purchaser to retain this manual for reference. This manual must be kept with, and supplied
with the pump at all times. Failure to comply with the recommendations stated in this manual will damage the pump,
and void factory warranty. These instructions are available if required, in the language or languages of the country or
countries in which the equipment is used. Please refer to the manufacturer for details.
