DataTrak Operation
See DataTrak manual 313840 for all DataTrak
information and parts, including detailed operation

Maintenance
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 pump.
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 fasteners.
Tighten or retorque as necessary. Although pump use
varies, a general guideline is to retorque fasteners every
two months. See Torque Instructions, page 18.

Flushing and Storage
•
Flush before fluid can dry in the equipment, 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.
Flush the pump often enough to prevent the fluid you
are pumping from drying or freezing in the pump and
damaging it. Use a compatible solvent.
Always flush the pump and relieve the pressure before
storing it for any length of time.
