NOTICE:
Some volume of bearing grease MAY ac-
cess the main chamber and contact the
pumping liquid. Any compatibility issues
between grease and liquid should be in-
vestigated prior to use of pump.
NOTICE:
To avoid possible injury or entanglement
with moving parts, do not lubricate pump
bearings, couplings or any other parts
while the pump is running.
NOTICE:
Any maintenance should follow the appro-
priate procedures and warnings presented
in this manual.

fittings which allow grease to lubricate the brass bushings. The pumps come fully lubricated with Metalon®

Tech EP 1.5 grease and are ready for use. This grease
’
s penetration rating bridges the NLGI #1 and #2
grades. Once your pump is in operation, it is absolutely critical that a regular lubrication program be fol-
lowed to allow the pump to operate as designed and to prevent premature failure.
We recommend the following lubrication

Best Practices
’:
•
Lubricant:
Select grease with the following properties: water resistance, rust and corrosion protec-
tion, extreme pressure protection and film strength and stability through temperatures ranging
from
-
40°C/F to 300°C/570°F.
•
Quantity and Time for Normal Operating Conditions:
Bowie recommends 2
-
4 ounces of grease
applied approximately every four (4) operating hours in the front drive neck of the pump. For all
other grease fitting locations, we recommend 1
-
2 ounces of grease applied every four (4) operating
hours. The actual amount of grease to be applied can be identified as the point when high re-
sistance to further greasing has been achieved. For operating conditions above those specified
refer to the above notice.
Normal operating conditions for greasing practices are:
•
Operating Temperature
≤
90° C (Progressive Helical Steel Gears) or
≤
50° C (Buna
-
N rubber Gears)
•
Rotation Speed
≤ 500
RPM
•
Discharge Pressure
≤ 70
PSI
NOTICE:
Strainers must be cleaned regularly to
avoid pump starvation. Schedule is de-
pendent upon the application and
conditions.
PREVENTATIVE MAINTENANCE
NOTICE:
For operating conditions ABOVE NORMAL, Bowie recommends 2
-
4 ounces of grease ap-
plied approximately every two (2) operating hours in the front drive neck of the pump. For
all other grease fitting locations, we recommend 1
-
2 ounces of grease applied every two (2)
operating hours. The actual amount of grease to be applied can be identified as the point
when high resistance to further greasing has been achieved.
Failure to set vehicle emergency
brake and chock wheels before
performing service can cause
severe personal injury or prop-
erty damage.
Failure to disconnect and lock-
out electrical power or engine
drive prior to performing ser-
vice can cause personal injury
or property damage.
Failure to relieve system pres-
sure prior to performing ser-
vice can cause personal injury
and property damage
If pumping hazardous or toxic
fluids, pump must be flushed
before service.
