MODEL 80BV VARIABLE VOLUME PUMP, 80BX
BYPASS HEAD PUMP, 80B SOLID HEAD PUMP RATED
80 GPM @ 540RPM (MAXIMUM RATING 88 GPM @ 600 RPM)
PUMP INTO SERVICE
When receiving pump, carefully check for damage,
broken port seals, and misalignment incurred during
PIPING HOOK-UP: The series 80 pump comes with
four 2" N.P.T. ports designed for use with
schedule 40 steel pipe. Connect piping based on
direction of shaft rotation.
80 CW (CLOCKWISE) rotation pump has two suction
port on the right side and two discharge ports
on left (VIEWED WITH SHAFT END TOWARDS YOU), and
indicated by arrows cast into body.
80CCW (COUNTER CLOCKWISE) rotation pump has
two suction ports on the left side and two discharge
ports on right side.
pump may be run in reverse temporarily for such
purposes as stripping lines etc.
WARNING: CAVITATION COULD ENSUE
following could cause misalignment:
base plate (correct by shimming pump and drive
strain (correct by using hangers or appropriate
pump is connected to drive member by couplings,
shim components until coupling halves are aligned.
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 and drive shafts are misaligned.
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 or plastic.
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 otherwise
fibre motor pinion life will be short.
WE ARE NOT RESPONSIBLE FOR ANY ITEM NOT OF OUR
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.
