1. Precautions for handling Warning ! 1) Operating environment When dangerous fluid or fluid possibly harmful to human is used, take measure to isolate human from • the pump. Should the external leakage of transported fluid come out, the serious damage to human could be caused.
2. Precaution for installation Caution ! 1) Mounting Only horizontal mounting is available. When the pump is not mounted horizontally with its bottom • faced down, it may cause sucking failure. • Use four M8 bolts to mount the pump. If the bolts are not tightened firmly, the pump could be exposed to the vibration and eventually damage.

Do not close valve suddenly, as it generates surge and remarkably shortens pump life.

7. Discharge capability 1) Flow characteristic With reference to flow characteristic graph (shown below), operating condition of the pump can be set. SUP=0.5MPa 0.4MPa 0.3MPa 0.2MPa Discharge rate (L/min) Recommended typical condition A: Obtain pilot air pressure when discharge rate is 20L/min and discharge pressure is 0.2MPa. <Assumption;...

2) Viscosity characteristic With reference to viscosity characteristic graph (shown below), discharge amount of transported fluid with higher viscosity can be calculated. 1000 Viscosity (mPa s) 粘 度(mPa・s) Recommended typical condition B: Calculate discharge amount of fluid with viscosity 100mPa s in case of discharge rate 9L/min and discharge pressure 0.2MPa.
8. Troubleshooting If any abnormality is found, perform check along with the following list. If the abnormality can’t be eliminated, return the pump to SMC. Warning ! Exhaust dangerous fluid out of the pump before check. • Do not return the pump with dangerous fluid left. Be sure to substitute it with DI water. Otherwise, the fluid could cause burn and other damages on human during transportation.
