Operation
CAUTION
・ When the pump is shut down while pumping liquids containing slurry, particulate slurry matter contained in the liquid can settle
and become deposited inside the bottom of the liquid chambers. If the pump is started again in the condition, the diaphragm
may be damaged or the center disk may be overloaded, and this may cause damage such as bending or breaking of the center
disk or center rod. As a counter measure, after finishing work, it is recommended to purge the remaining fluid and slurry
particulate from the pump.
4.Releasing pressure
1) Make sure that the airline ball valve of the pump is closed.
2) Close the valve on the air-supply side of the peripheral equipment.
3) Close the flow valve on the discharge side, start opening the drain valve slowly, and discharge the pressurized fluid.
4) Open the airline ball valve of the pump, and run the pump until all the remaining pressurized air and liquid inside the pump is expelled.
CAUTION
・ Fluid under pressure will gush out as soon as you open the valve, so take extreme care.

5.Method of cleaning the pump
WARNING
・ Before starting operation, make sure that the pump is not pressurized.
!
!
・ Be careful when removing any piping from the pump as any remaining fluid may gush out.
1) Remove the inlet 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 opening the air pressure valve for a while
to discharge any fluid remaining inside the pump.
3) Remove the outlet hose from the discharge side, and attach different hoses to the suction side and the discharge side for cleaning
purposes.
4) Prepare a vessel with cleaning solution, select a cleaning solution which is appropriate for the type of fluid being pumped, and then
connect the suction-side and the discharge-side hoses to the pump.
5) Operate the pump by starting the air pressure slowly, and let the cleaning solution circulate for a sufficient period to thoroughly clean
the pump. （Finally, flush the pump with clean water.）
6) Remove the hose from the suction side of the pump, run the pump for a while and purge the pump of all remaining fluid.
7) After flushing with clean water, turn the pump upside-down to drain out any remaining water contained in the pump.
