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.
The air valve is designed to operate unlubricated. If
lubrication is desired, every 500 hours of operation (or
monthly) remove the line from the pump air inlet and
add two drops of machine oil to the air inlet.
NOTICE
Do not over-lubricate the pump. Lubricant is
exhausted through the muffler and could contaminate
your fluid supply or other equipment. Excessive
lubrication can also cause the pump to malfunction.
Flushing and Storage
•
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
connectors for leaks and tighten as necessary.
•
Flush with a sanitizing solution that is compatible
with the fluid being dispensed and the equipment
wetted parts.
•
Flushing schedule will vary based on particular
uses.
•
Always cycle the pump during the entire flushing
process.
Always perform the Pressure Relief Procedure, page
13, and flush the pump before storing it for any length of
time.
1. Insert suction tube into sanitizing solution.
2. Open air regulator (B) to supply low pressure air to
the pump.
3. Run the pump for enough time to thoroughly clean
the pump and lines.

4. Close the air regulator.
5. Remove the suction line from the sanitizing solution
and drain pump.
Routine Cleaning of Product
Contact Section of Pump
NOTE: The pump and the system should be cleaned in
accordance with your state sanitary standard codes and
local regulations.
1. Flush the system. See Flushing and Storage.
2. Follow the Pressure Relief Procedure, page 13.
3. If disassembly of the pump is required for cleaning,
refer to the appropriate repair manual.
4. Using a brush or other C.O.P. methods, wash all
product contact pump parts with a sanitizing
solution at the manufacturer's recommended
temperature and concentration.
5. Rinse these parts again with water and allow parts
to completely dry.
6. Inspect the parts and re-clean any soiled parts.
7. Immerse all product contact parts in an approved
sanitizer before assembly. Leave the parts in the
sanitizer, taking them out only one by one as
needed for assembly.
8. Lubricate the clamps, clamping surfaces, and
gaskets with waterproof sanitary lubricant.
9. Circulate the sanitizing solution through the pump
and the system prior to use. Cycle the pump as the
sanitizing solution is circulated.
Tightening Connections
Before each use, check and tighten all pump clamps
and fluid connections before operating the equipment.
Replace worn or damaged parts as necessary.
