12.0 Method of cleaning
Caution
• Before starting operation, make sure that compressed air is not supplied to the pump.
• Before starting operation, make sure that the pump is not pressurised.
1) Remove the hose from the suction side of the pump.
2) Close the flow valve on the discharge side, open the drain valve, and then operate a pump
by starting air pressure for a while to discharge any fluid remaining inside the pump as much
as possible.
3) Remove the hose from the discharge side, and attach different hoses to the suction side and
the discharge side for cleaning.
4) Be ready with a vessel with cleaning solution, select cleaning solution appropriate for the
type of fluid pumped, and then connect the suction-side and the discharge-side hoses of the
pump.
5) Operate a pump by starting air pressure slowly, and let the cleaning solution circulate for
sufficient cleaning.
6) Finally, flush with clean water.
7) Remove the hose from the suction side of the pump, run the pump for a while and purge the
pump of remaining fluid as much as possible.
Caution
• Be careful when removing piping. Fluid will gush out.
• After cleaning with clean water, turn the pump upside-down to drain out the water.
13.0 Daily check
• Before starting pump operation, be sure to conduct the following check every day. If any
irregularity is found, do NOT start running the pump until the cause of the irregularity has
been found and corrective measures have been taken.
a) Verify the drain flow through the air filter.
b) In the case of using a lubricator, verify the quantity of lubricating oil.
c) Make sure that there is no leakage of fluid from any connection part or the pump.
d) Make sure that there are no cracks in the pump casing or piping.
e) Check the tightness of every bolt of the pump.
f) Make sure that the connection parts of the piping and peripheral equipment are not
loose.
g) Make sure that the time has not elapsed for replacing any parts of the pump that are to
be replaced at regular intervals.
