PUMPS: INSTALLATION AND
OPERATING INSTRUCTIONS
Introduction:
This document contains specific information
regarding the safe installation, operating and
maintenance of Vertical In-Line pumps and
should be read and understood by installing,
operating and maintenance personnel. The
equipment supplied has been designed and
constructed to be safe and without risk to health
and safety when properly installed, operated and
maintained. The instructions following must be
strictly adhered to. If clarification is needed on
any point please contact Armstrong quoting the
equipment serial number.
Where under normal operating conditions the
limit of 68°C/155°F (Restricted Zone) for normal
touch, or 80°C/176°F (Unrestricted Zone) for
unintentional touch, may be experienced, steps
should be taken to minimize contact or warn
operators/users that normal operating conditions
will be exceeded. In certain cases where the
temperature of the pumped liquid exceeds the
above stated temperature levels, pump casing
temperatures may exceed 100°C/212°F and not
withstanding pump insulation techniques
appropriate measures must be taken to minimize
risk for operating personnel.
Storage:
Pumps removed from service and stored, must be
properly prepared to prevent excessive rusting.
Pump port protection plates must not be removed
until the pump is ready to connect to the piping.
Rotate the shaft periodically (At least monthly)
to keep rotating element free and bearings fully
functional.
For long term storage, the pump must be placed
in a vertical position in a dry environment.
Internal rusting can be prevented by removing
the plugs at the top and bottom of the casing and
drain or air blow out all water to prevent rust
buildup or the possibility of freezing. Be sure to
reinstall the plugs when the unit is made
operational. Rustproofing or packing the casing
with moisture absorbing material and covering
the flanges is acceptable. When returning to
service be sure to remove the drying agent from
the pump.
Handling Large VIL Units:
One effective way of lifting a large pumping unit
is to place lifting hooks through the motor lifting
rings or straps around the upper part of the
motor. The pump and motor unit will free-stand
on the casing ribs. Remove the coupling guard
and place (2) lifting straps through the
pump/motor pedestal, one on each side of the
motor shaft and secure to the lifting device.
With the straps in place, using a spacer bar if
necessary to protect the motor fan cover, the
whole assembly can now be lifted securely.
Note:
Handling, transportation and installation of
this equipment should only undertaken by trained
personnel with proper use of lifting equipment.
Remove coupling guard and place lifting straps
on each side of coupling, use spacer bar if
necessary to protect motor fan cover.
