Maintenance
Preventive Maintenance Schedule
The operating conditions of your particular system
determine how often maintenance is required. Estab-
lish a preventive maintenance schedule by recording
when and what kind of maintenance is needed, and
then determine a regular schedule for checking your
system.
1.
Purge and lubricate the packing area. There is a
grease cavity between the two “U” cup shaft
packings. This area should remain sealed with
grease fittings or pipe plugs during operation.
Periodically remove the plug from one side of the
housing and push the old grease and sealant out
from the other side with fresh grease. This should
be done every 50,000 cycles, or as required for
your sealant and process. A high quality synthetic
grease is recommended.
2.
Grease the ball screw at least every 30,000 to
40,000 cycles with a following recommended
grease or equivalent.

Keep rupture disc exhaust tube (51), see System
Parts, page 20, clear at all times.
Flushing the System
WARNING
Use fluids and solvents that are chemically compat-
ible with the equipment wetted parts. See the
Technical Data
sections of all the equipment
manuals. Always read the material manufacturer’s
literature before using fluid or solvent in this equip-
ment.
To avoid damaging the unit do not use fluids con-
taining halogenated hydrocarbons (HHC) to flush or
clean the system as HHC is not compatible with
aluminum. See technical data on page 24 for a list
of wetted parts.
Flush the pump:
D
Before the first use
D
When changing material or fluid part number or
brand
D
Before fluid can dry or settle out in a dormant pump
(check the shelf life or pot life of catalyzed fluids)
D
Before storing the unit.
Flush with a fluid that is compatible with the fluid you
are pumping and with the wetted parts in your system.
Check with your fluid manufacturer or supplier for
recommended flushing fluids and flushing frequency.
WARNING
FIRE AND EXPLOSION HAZARD
Be-
fore flushing, read the section
FIRE
AND EXPLOSION HAZARD
on page 4.
Be sure the entire system and flushing
pails are properly grounded. Refer to
Grounding
on page 7.
