Many components of LINCOLN Air-Operated 

Diaphragm  pumps  are  made  of  recyclable 

materials (see chart on page 9 for material 

specifications). We encourage pump users to 

recycle worn out parts and pumps whenever 

possible, after any hazardous pumped fluids 

are thoroughly flushed.

CE

Before  pump  operation, 
i n s p e c t   a l l   g a s k e t e d 
fasteners  for  looseness 
caused by gasket creep. Re-
torque  loose  fasteners  to 

prevent leakage. Follow recommended torques 
stated in this manual.

CaUtION

Before  maintenance  or 
repair,  shut  off  the  com-
pressed  air  line,  bleed  the 
pressure,  and  disconnect 
the air line from the pump. 
The discharge line may be 

pressurized and must be bled of its pressure. 

WarNINg

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.

WarNINg

When  used  for  toxic  or 
aggressive fluids, the pump 
should  always  be  flushed 
clean prior to disassembly.

WarNINg

WarNINg

Airborne particles and 
loud noise hazards.
Wear ear and eye 
protection.

Before  doing  any  main-
tenance  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 all times in the vicinity of the 
pump. Failure to follow these recommendations 
may result in serious injury or death.

WarNINg

WarNINg

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 hazardous or toxic, 
the air exhaust must be piped to an appropriate 
area for safe disposition.
