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.
Maintenance Schedule
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
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.
Tighten Threaded Connections
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.
See Torque Instructions, page 22 .
Flushing and 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 ofthe 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
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.
