Maintenance
Lubrication
The air valve is designed to operate unlubricated,
however if lubrication is desired, every 500 hours of
operation (or monthly) remove the hose from the pump
air inlet and add two drops of machine oil to the air inlet.
Flushing
Insert suction tube into cleaning solution. Open air
regulator to supply low pressure air to the pump. Run
the pump long enough to thoroughly clean the pump
and hoses. Close the air regulator. Remove the suction
tube from the cleaning solution and drain pump. Place
suction tube in the fluid to be pumped.
Flush the pump often enough to prevent the fluid you
are pumping from drying or freezing in the pump and
damaging it. Flushing schedule will be based on what
the pump is being used for. Use a compatible cleaning
solution and always cycle the pump during the entire
flushing process.
Always flush the pump and relieve the pressure before
storing it for any length of time.
Tightening Connections
Before each use, check all hoses for wear or damage,
and replace as necessary. Check to be sure all
connections are tight and leak-free.
Preventive Maintenance Schedule
Establish a preventive maintenance schedule, based on
the pump’s service history. This is especially important
for prevention of spills or leakage due to diaphragm
failure.
NOTICE
Do not over-lubricate the pump. Oil is exhausted
through the muffler and could contaminate your fluid
supply or other equipment. Excessive lubrication can
also cause the pump to malfunction.
