Maintenance Maintenance Maintenance
To avoid injury from fire, explosion, or electric
shock, all electrical wiring must be done by a
qualified electrician and comply with all local codes
and regulations.
To avoid injury from fire, explosion, perform all
maintenance and repair outside of hazardous
location.

Maintenance Schedule
Schedule
Schedule
Items such as balls and seats, diaphragms, and other
seals will wear out from normal pump operation.
These items must be inspected periodically to ensure
that they are not worn. Replace them if they are worn
or damaged. Establish a preventive maintenance
schedule based on the pump’s service history.
Scheduled maintenance is especially important to
prevent spills or leakage due to diaphragm failure.
Lubrication Lubrication Lubrication
The pump is lubricated at the factory. It is designed
to require no further lubrication for the life of the
bearings. There is no need to add an inline lubricator
under normal operating conditions.

Before each use, check all hoses for wear or damage
and replace as necessary. Check to be sure all
threaded connections are tight and leak-free. Check
mounting bolts. Check fasteners. Tighten or retorque
as necessary. Although pump use varies, a general
guideline is to retorque fasteners every two months.

Storage
To avoid injury from fire, explosion, or electric
shock, always ground equipment and waste
container. To avoid static sparking and injury from
splashing, always flush at the lowest possible
pressure.
• Flush before first use.
• Flush at the end of the day, before storing, and
before repairing equipment.
• Flush at the lowest pressure possible. Check
connectors for leaks and tighten as necessary.
• Flush with a fluid that is compatible with the fluid
being dispensed and the equipment wetted parts.
• Always flush the pump and relieve the pressure
before storing it for any length of time.
NOTICE NOTICE NOTICE
Flush the pump often enough to prevent the
fluid you are pumping from drying or freezing in
the pump and damaging it. Store the pump at
0°C (32°F) or higher. Exposure to extreme low
temperatures may result in damage to plastic parts.
