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 absorb-

ing material and covering the flanges is acceptable. When

returning to service be sure to remove the drying agent from

the pump.

uncr ating

Armstrong Vertical In-Line pumps are thoroughly inspected

before shipment to assure they meet with your order require-

ments. After removing the pump from the crate, make sure

the equipment is in good order and that all components are

received as called for on the packing list. Any shortages or

damage should be reported immediately. Use extreme care

in handling the unit, placing slings and hooks carefully so that

stress will not be imposed on the pump. Never Place Cable

Slings Around The Pump Shaft. The eye bolts or lifting lugs

on the motor are intended for lifting only the motor and not

the complete unit.

handling

large vil units

One effective way of lifting a large Series 430 0 unit from the

shipment pallet following uncovering the unit is to place lift-

ing hooks through the motor lifting rings or straps around the

upper part of the motor and carefully lift sufficiently to stand

the pump vertically. Lift only sufficiently to remove the pallet

then lower onto a flat surface. 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 neces-

sary to protect the motor fan cover, the whole assembly can

now be lifted securely and placed in position in the piping.

Secure pallet and lift pump vertical using motor eye-bolts lift

Vertical in–line pumps

Remove coupling guard and place lifting straps on each side

of coupling, use spacer bar if necessary to protect motor fan

cover.

important:

Do not run the pump for any length of time under

very low flow conditions or with the discharge valve

closed. To do so could cause the water in the casing

to reach super heated steam conditions and will cause

premature failure and could cause serious and dramatic

damage to the pump and surrounding area.

installation

location

• In open systems, locate the unit as close as practical to

the liquid being pumped, with a short, direct suction pipe.

Ensure adequate space is left above and around the unit

for operation, maintenance, service and inspection of

parts.

• In closed systems, where possible, the pumps should be

installed immediately downstream of the expansion tank

/ make-up connection. This is the point of zero pressure

change and is necessary for effective pump operation. Do

not install more than one expansion tank connection into

any closed hydronic system.

• Electric motor driven pumps should not be located in

damp or dusty location without special protection.

• Airflow into the motor and/or motor fan should not be

obstructed.

installation

• When installing vertical in-line pumps, an important

consideration to accrue full added-value from the pump

design is to ensure that the pump is pipe-mounted

and free to 'float' with any movement, expansion and

contraction of the piping. Should any vertical in-line pump

use supports to the structure it is imperative that no pipe
