Maintenance 

10. If you are flushing, run the pump long 

enough to thoroughly clean the pump and 
hoses.

11. Close the dispensing valve, if used.

12. Close the bleed-type master air valve.

13. Pumps with runaway protection: Disable 

the prime/flush function by pushing the 
prime/flush button on the DataTrak.

See DataTrak manual 313840 for all DataTrak 
information and parts, including detailed oper-
ation instructions.

At the end of the work shift and before you 
check, adjust, clean or repair the system, fol-
low Pressure Relief Procedure, page 15.

Establish a preventive maintenance schedule, 
based on the pump’s service history. Sched-
uled maintenance is especially important to 
prevent spills or leakage due to diaphragm
failure.

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.

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 17.

•

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 compati-
ble solvent. 

Always flush the pump and relieve the pres-
sure before storing it for any length of time.
