PERFORMANCE CURVE :

DIMENSIONS :

IV. INSTALLATIONS :
1.	Adopt foot stand 53 gallon tank covered with wall mounted & mobile car.
2.	The air inlet must be installed with the air cleaner to prevent dirt from entering into the air pilot valve and damaging components.
3.	Employ single pipe and prevent dead angles in order to maintain smooth transporting.
4.	The piping length should not exceed more than 10m to ensure proper pressure in transporting.

V. HOW TO OPERATE :
1.	Adjust the operating pressure accordingly to the transporting range.
2.	The operating pressure cannot be less than 1.5kg/cm²^.^{If there is a shortage of air pressure, the pump will not be operated smoothly and it can possibly cause pump to be clogged.}
3.	Everyday, the piping system must be cleaned after the work. Especially, when the pump is used for heavy viscosity painting. It is highly recommended that pumps should be cleaned completely for clog-free operation afterward.

VI. TROUBLE SHOOTING :
