MODEL 40AX BYPASS
HEAD PUMP, 40A SOLID HEAD PUMP
RATED 40 GPM @ 540 RPM (MAXIMUM RATING
42 GPM @ 600 RPM)
PUMP INTO SERVICE
When receiving pump, carefully check for
damage, broken port seals, and misalignment
incurred during shipping.
PIPING HOOK-UP: The series 40 pump
comes with two 2" N.P.T. ports (1
1/2" optional) designed for use with
schedule 40 steel pipe. Connect piping
based on direction of shaft rotation.
40 CW (CLOCKWISE) rotation pump has
the suction port on the right side and
discharge port on top (VIEWED WITH SHAFT
END TOWARDS YOU).
40 CCW (COUNTER CLOCKWISE) rotation
pump has the suction port on the left
side and discharge on top.
pump may be run in reverse temporarily
for such purposes as stripping lines
WARNING: CAVITATION COULD
following could cause misalignment:
base plate (correct by shimming pump
and drive components)
strain (correct by using hangers or
appropriate pipe supports)
pump is connected to drive member by couplings,
shim components until coupling halves
prevent misalignment of pump and drive
components, fasten base securely in place
using the foundation bolt holes provided.
SHOULD ALWAYS BE TURNABLE BY HAND
a last check before starting pump: remove
gland nuts and slide packing gland out
of housing. If gland does not slide
into housing without interference, pump
MOTOR DRIVE "(M and SM)" UNITS
and GEAR DRIVEN "(GR)" UNITS:
Abutting shafts must be at least 1/8 of
an inch apart and coupling inserts and/or
chains should be loose enough to prevent
end thrust on pump shaft. We recommend
couplings with metal inserts, not rubber
DRIVEN "(BD)" UNITS and OPEN
GEAR "(MO)" UNITS: An outboard
bearing must be used to prevent side thrust
on pump shaft. Pump shaft must be free
to slide longitudinally through outboard
bearing, so that rotor group will not
be forced against pump case components.
For BD units, align sheaves using straight
edge or stretched cord. For MO units,
proper alignment and engagement of gear
and pinion can be checked by passing foil
or cellophane through them. CAUTION: Use
gear and pinion set of same pressure angle
else fibre motor pinion life will be short.

OF OUR MANUFACTURE.
packing gland serves a dual function;
first as packing follower and second as
a bearing which, with the shaft housing
bushing, forms a support for the rotor
and shaft. As shipped from the factory
the gland is LOOSE ENOUGH TO BE ROCKED
BY HAND. At first startup DO NOT tighten
gland until pump has run long enough for
packing to expand from absorption of pumpage.
Thereafter, to adjust, tighten nuts evenly
one-quarter turn at a time and adjust
enough to reduce leakage - NO MORE - a
drop or two of the pumpage should normally
drip from the gland every few minutes
(except, of course, with mechanical seals
or external scavenging systems.) SHAFT
SHOULD ALWAYS BE TURNABLE BY HAND. LUBRICATE
SHAFT, THROUGH FITTING PROVIDED, WHILE
PUMP IS UNDER OPERATING PRESSURE A MINIMUM
OF EVERY 8 HOURS DURING NORMAL OPERATION.
This applies for pumps with Zero Leak
Packings or Mechanical Seals to prevent
forcing the lubricant back through the
packing or seal. For pumps with Food Grade
Packing, use only FDA approved lubricant.
