NOTICE:
Maintenance shall be performed by qualified technicians
only. Follow the appropriate procedures and warnings
as presented in this manual.
SCHEDULED MAINTENANCE
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 GX 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.
STRAINERS
Strainers must be cleaned regularly to avoid pump starvation.
Schedule will depend upon the application and conditions.
