CAUTIONS FOR OPERATION
Installation
Cautions for Piping
Item Caution
Applied
Type
Installed direction. Install pump with drive shaft horizontal in general. All types.
External load to
shaft end. Apply neither radial nor thrust load externally to the pump shaft
end. All types.
Removal of rust
preventing paint. Since the shaft end splined section has been coated with rust
preventing paint, remove it with cleaning liquid before using the
pump. Apply lubricant, such as molybdenum disulfide, before
installing this section on the coupling. When cleaning liquid is
used, be careful not to get liquid on oil seal sections. All types.
Coupling and
centering of pump. Couple the pump drive shaft with the prime mover shaft with a
flexible coupling in general. For centering between the coupling
and drive shaft, keep the alignment within
±
0.03mm.
All types.
Tightening of pump
mounting bolts. For the tightening torques of the pump mounting bolts, refer to
the values of their respective sizes shown in “Tightening
Torques” on page 26. All types.
Item Caution
Applied
Type
Rotating direction
and delivery
direction. For the variable pump, these indications depend on the
command method of the regulator. For each application of the
pump, refer to the indications shown in the outside dimension
drawing. All types.
Sanitation of
pipings. Carry out acid pickling and flushing of the suction / delivery
pipings and tank. Especially, thoroughly clean the suction piping. All types.
Installation of
suction / delivery
pipings. When installing pipings, prevent the suction and delivery ports of
the pump from being forcedly-stressed.
Also avoid sudden bending as much as possible. Refer to
attached list 1 tightening torque list in tightening the mounting
bolts.
All types.
Drain piping. Raise the drain pipe of the pump higher than the pump and
route it to the tank, as shown in the following figures.
For a tandem type double-pump, install the drain pipe on the
front pump first as far as possible. It is desirable to provide a
filter in the drain line.
All types.
Tandem type
pumps.
Drain pressure. Allowable internal case pressure for this pump is normally less
than 1 kg/cm
2
.(14 psi).
All types.
