¡á Mount the pump with the shaft directed
horizontally as shown in the right figure.
¡á The drain line must be arranged
above the top of the pump case before reaching the tank.
¡á The upper drain port should be
used, and the drain pipe size must be equal to or larger than
the drain port size so that the drain
pressure in the casing does not exceed 0.2MPa(2kgf/§²)

¡á For satisfactory service life of
these pumps in application, the operating
fluid should be continuously filtered to
the minimum cleanliness level of NAS1638
Class 9.
¡á A 10§ filter must be used in the
return line and an 80~150mesh strainer,
in the suction line.

¡á Use a flexible coupling for connection
of the pump
drive shaft with an engline flywheel or an
electric
motor shaft.
¡á Alignment should be so carried
out that the parallel
error may be held within ¡¾0.025§®
¡á Do not put radial or thrust load
at the shaft end.
¡á The standard of alignment :
¡á Æí- Parallel misalignment ¥ä<=0.025mm
¡á Æí -(Dial gage reading b>=0.05mm)
¡á Æí- Angular misalignment ¥á<=0.025deg

¡á Before starting-up, fill the pump
casing with the system fluid through the case drain connection
because
the casing must remain full of fluid to porvide
internal lubrication
|
|
| |
 |
| |
¡á Please be careful so that the drain
pressure in
the casing does not exceed 0.2Mpa(2kgf/§²)
normally and 0.6Mpa(6.kgf/§²) at its peak
