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 and Storage
Flush the pump often enough to prevent the fluid you are
pumping from drying or freezing in the pump and damaging
it. Flush with a fluid that is compatible with the fluid you are
pumping and with the wetted parts in your system. Check
with your fluid manufacturer or supplier for recommended
flushing fluids and flushing frequency.
Always flush the pump and relieve the pressure before
storing it for any length of time.
Tightening 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 Diaphragm Kits, page 29.
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.
Caution
Do not over-lubricate the pump. Oil is exhausted through the
muffler, which could contaminate your fluid supply or other
equipment. Excessive lubrication can also cause the pump
to malfunction.
Warning
To reduce the risk of serious injury whenever you are
instructed to relieve pressure, always follow the Pressure
Relief Procedure on page 13.
