MAINTENANCE
Failure to disconnect and lockout
electrical power before attempting
maintenance can cause shock, burns or
death
Hazardous voltage.
Can shock, burn or
cause death.
Failure to disconnect and lockout
electrical power or engine drive before
attempting maintenance can cause
shock, burns or death
Hazardous
machinery can
cause serious
personal injury.
Failure to relieve system pressure prior
to performing pump service or
maintenance can cause serious
personal injury or property damage.
Systems with meters will still be
pressurized even after the hose is
emptied
Hazardous pressure
can cause serious
personal injury or
property damage
Disconnecting fluid or pressure
containment components during pump
operation can cause serious personal
injury, death or major property damage
Hazardous pressure
can cause personal
injury or property
damage
If pumping hazardous or toxic fluids,
system must be flushed and
decontaminated, inside and out, prior
to performing service or maintenance
Hazardous or toxic
fluids can cause
serious injury.
Always use a lifting device capable of
supporting the full weight of the pump
assemblies.
Heavy assemblies
can cause personal
injury or porperty
damage.
NOTICE:
Maintenance shall be performed by qualified technicians
only, following the appropriate procedures and warnings
as presented in this manual.

SCHEDULED MAINTENANCE
STRAINERS
Strainers must be cleaned regularly to avoid pump starvation.
Schedule will depend upon the application and conditions.
LUBRICATION
NOTICE:
To avoid possible entanglement in moving parts do not
lubricate pump bearings, gear reducer or any other parts
while the pump is running
.
NOTICE:
If pumps are repainted in the field, ensure that the grease
relief fittings (76A) are functioning properly after
painting. Do NOT paint them closed. Remove any
excess paint from the fittings.
Ball bearings must be lubricated every three months at
minimum. More frequent lubrication may be required
depending on the application and operating conditions.
Recommended Grease:
Dow Corning
® -
MOLYKOTE 44
DuPont
® -
KRYTOX GPL 203
NOTICE
:
Use ONLY recommended grease.
Using petroleum based
grease or oil to lubricate seal O-rings WILL cause seal O-ring
damage and subsequent product leakage.
Greasing Procedure:
1. Remove the grease relief fittings (76A) from the bearing
covers (27 and 27A).
2. SLOWLY apply grease with a hand gun until grease
begins to escape from the grease relief fitting port.
Discard excess grease in accordance with proper codes
and regulations.
3. Replace the grease relief fittings (76A).
DO NOT overgrease pump bearings. While it is normal
for some grease to escape from the grease tell-tale hole
after lubrication, excessive grease can cause mechanical
seal failure. The tell-tale hole is located in the head or
hub between the bearing and the seal.
Lubricate the ball bearings, and hydraulic motor
couplings (if equipped), every three months at a
minimum
