Maintenance
Establish a Preventive
Maintenance Schedule
NOTICE
Regularly maintain the equipment to avoid pump
damage due to spills, leaks, or diaphragm failure.
Establish a preventive maintenance schedule based on
the equipment service history.
Inspect the Equipment
Regularly inspect the equipment for worn or damaged
parts. Replace as needed.
Tighten Fasteners
Regularly check and torque all fasteners. Follow
Torque Fasteners, page 39.
NOTICE
To avoid pump damage, do not over-torque the
fasteners on the equipment.
Tighten Connections
Check and tighten all fluid connections before operating
the equipment. Replace worn or damaged parts as
needed.
NOTICE
Firmly tighten all connections to avoid leaks and
damage to equipment parts.
Lubricate the Equipment
The equipment is lubricated at the factory. Re-lubricate
the equipment when replacing diaphragms.
Lubricate the motor rotor when replacing diaphragms.
See your related motor manual. See Related Manuals,
page 2.
NOTICE
Do not over-lubricate the equipment. Lubricant
exhaust could contaminate your fluid supply or other
equipment. Excessive lubrication can also cause the
equipment to malfunction.

Flush the Equipment
To avoid fire and explosion, always ground the
equipment and waste container. To avoid static
sparking and injury from splashing, always flush at
the lowest possible pressure.
•
Flush before fluid can dry or freeze in the
equipment, at the end of the day, before storing,
and before repairing equipment.
•
Flush at the lowest pressure possible. Check
connections for leaks and tighten as needed.
•
Flush with a solvent that is compatible with the fluid
being dispensed and the equipment wetted parts.
Use a sanitary solution for hygienic applications.
•
Flushing schedule varies based on particular uses.
•
Always cycle the equipment during the entire
flushing process.
1. Follow Pressure Relief Procedure, page 22.
2. Insert the suction end of the fluid supply line (F) into
a compatible solvent.
3. Close the fluid drain valve (G).
4. Ensure the control knob (K) is turned to off (0).
5. If the fluid outlet line (J) has a dispensing device,
place a metal part of the dispensing device to a
grounded metal container and hold the dispensing
valve open.
6. Ensure all fluid shutoff valves (H) are open.
7. Connect the equipment to a power source. See
Electrical Connections and Wiring, starting on
page 17.
8. Slowly increase the control knob (K) until the
equipment is operating at the set output level.
9. Run the equipment for enough time to thoroughly
clean the equipment and lines.
10. Turn the control knob (K) to off (0).
11. Follow Pressure Relief Procedure, page 22.
