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.
Operation without guards in place can
cause serious personal injury, major
property damage, or death.
Do not operate
without guard
in place
NOTICE:
Maintenance shall be performed by qualified technicians
only. Follow the appropriate procedures and warnings
as presented in this manual.
SCHEDULED MAINTENANCE
PUMP 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:
The inboard bearings of GNX(H) models shipped without
the gear reducer attached are NOT greased at the
factory. The inboard bearing MUST be greased after
installation of the gear reducer and prior to initial pump
start up.
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.
Pump bearings should be lubricated every three months at
minimum. More frequent lubrication may be required,
depending on the application and operating conditions.
Recommended Grease:
Mobil® - Mobilgrease XHP222,
Exxon® - RONNEX MP Grease,
or equivalent Lithium grease..
Greasing Procedure:
1. Remove the grease relief fittings (76A) from the bearing
covers (27, 27A).
2.
SLOWLY
apply grease with a hand gun until grease
begins to escape from the grease relief fitting port. (76)
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 on pumps equipped with
mechanical seals can cause seal failure.
If equipped with a Blackmer gear reducer, refer to the ‘Gear
Reducer Lubrication’ section of this manual.
PUMP SHAFT/GEARBOX COUPLING
An Anti-Seize compound should be applied to the end of the
pump shaft to help minimize fretting wear between the
gearbox coupling and pump shaft.
Recommended Anti-Seize Compound:
Loctite ® 39901 or equivalent
STRAINERS
Strainers must be cleaned regularly to avoid pump starvation.
Schedule will depend upon the application and conditions.
