The innovative Armstrong Series 4600 hsc pump is designed
to allow easy maintenance. The pumps same level suction
and discharge permits easy-piping layout and pump installation.
Design features, such as bearing removal with no special
tools, will make the reliable hsc pump a trouble-free pump for
many years.
Armstrong series 4600 hsc pumps are thoroughly tested and
inspected before shipping, but should be carefully examined for
possible damage during transit. Contact your Armstrong repre-
sentative and the transport company immediately if there is any
evidence of mishandling.

1.0. installation
1.1 location and storage
• Locate the unit in a dry place as near the city water en-
trance as practical with a short, direct suction pipe
• Shaft should be rotated by hand 10 to 15 revolutions every
one to three months depending on storage conditions
1.2. foundation for hsc pump
• Foundation should be suciently substantial to absorb
any vibration and to form a permanent, rigid support for
the base plate
• Foundation bolts of suitable size should be embedded in
the concrete located by a drawing or template
• Place pumping unit on foundation with wedges under
base plate leaving approximately ¾"space for grouting
• Carefully level the unit by adjusting the wedges until
shafts of pump and driver are leveled, recreating factory
alignment
• Check coupling faces as well as suction and discharge
flanges of pump for horizontal or vertical position with
a level
• Slight misalignment at this point may be corrected by
adjusting the wedges
After unit has been in operation for about a week, check align-
ment. Any misalignment may be corrected by placing shims
between base and driver or pump feet.
1.3. pump mounting and piping
• Never connect a pump to piping, always start piping
from pump
• Use as few bends as possible and preferably long
radius piping
• Install good supports under suction and discharge piping
with anchors near but independent of the pump
• Make sure piping exerts no strain on pump as this would
throw the unit out of alignment or distort the casing

• Increase the size of both suction and discharge pipes
at pump nozzle to suit pump capacity and particular
conditions of installation
• Use eccentric reducers on suction
• Lay out the suction line with a continual rise towards the
pump without high points, thus eliminating possibility of
air pockets
• Test suction line for air leaks before starting; this becomes
essential with long suction line or high static lift
• Install, at pump suction, a straight pipe of a length equiva-
lent to 4or 6times its diameter
• Install gate valve close to pump in both suction and
discharge lines on flooded suction application; this is used
mainly to isolate the pump for inspection or repair
• Install a check valve in discharge line between pump and
gate valve
caution: Only the discharge valve must be used to
reduce the flow or shuto the pump

1.4. alignment
The flexible coupling compensates for temperature changes
and permits shafts end movement without interference; it will
not compensate for misalignment. Faulty alignment will result in
noisy pump operation, reduced bearing life, and excessive
coupling wear.
• Carefully verify the alignment after the foundation bolts
have been properly tightened
• Alignment should be again verified after piping is installed
and unit has operated under normal conditions at operat-
ing temperature
• To verify alignment, place a straight edge across the cou-
pling as shown; this must rest evenly on both rims at top,
bottom and both sides
• With a pair of inside calipers or thickness gauge, check
distance between coupling halves at points where straight
edge was used; distance must be equal at all points
1.5. minimum fittings
If minimum fittings recommended by n.f.p.a. 20 are supplied
loose, they should be installed as follows:
circulation relief valve (not supplied with diesel driven
pumps)
• Install Circulation Relief Valve at the casing discharge (al-
ways before the check valve)
• Set pressure at the minimum suction pressure plus the pump
rated pressure raised to the next higher 5 lb. increment
• Circulation relief valve and stung box should then be piped
to drain
automatic air release valve
• Install automatic air release valve on top of pump casing
to vent casing and suction piping of air and vapor before
start-up.
suction and discharge gauges
• The following gauges are required to measure both suction
and discharge pressures, and must be supplied with all fire
pumps to ensure close check on pump performance:
a3½" dial combination pressure and vacuum suction gauge
b3½" dial discharge pressure gauge
c¼"cocks with lever handle

entire bearing life
• If abnormal noises come from the bearing during normal
operation, replace bearings
3.3. stuffing box with packing
stuffing box dismantling
• Adjust pressure of packing gland to obtain a slight leak of 6
to 8drops per minute for suction pressures up to 20 psig (the
increase in suction pressure causes proportional increase in
leakage through the stung box)
• Remove flush line connection from stung box extension
• Remove gland plate from stung box
• Remove stung box extension
packing replacement
• When removing old packing, make sure bottom rings are
completely removed

4.3 removal of impeller ring
It is not necessary to remove impeller from shaft to replace
impeller rings
1. Remove rotating element
2. Remove locking set screws from rings
3. Rings may now be pulled from impeller, cut o with a chisel,
or turned o if a suitable lathe is available using original shaft
centers - do not cut into body of impeller
4. When new rings are installed, drill and tap new holes for locking
set screws - do not attempt to use old half holes in impeller hub
4.4 inspection
1. Visually inspect parts for damage aecting serviceability
2. Check o-rings and gaskets for cracks, nicks or tears
3. Check packing rings for excessive compression, fraying or
shredding and embedded particles
4. Replace if defective in any way
5. Mount shaft between the lathe centers to check eccentricity
throughout the entire length, runo should not exceed 0.002".
6. Bearing surface should be smooth and shoulders square and
free of nicks
7. Measure od of impeller hub or impeller wear rings and id of
casing wear ring
8. Compute diametrical clearance (id minus od) and compare
with original (0.0075" to 0.0085") radial clearance
9. Surfaces must be smooth and concentric
10. Examine impeller passages for cracks, dents or embedded
material
11. Examine shaft sleeves for wear
