general descriptiOn
Fybroc vertical (Series 5500) and cantilever (Series
7500) pumps are centrifugal wet pit type pumping
units for installation in a pit or a tank vented to
atmospheric pressure. All pump parts in contact
with the fluid are constructed of glass reinforced
vinyl ester (VR-1) or epoxy (EY-1) resin with the
exception of the shaft and hardware, which are of
an alloy selected for compatibility with the fluid
pumped. Vertical pumps contain one or more non-
metallic line bearings which require a source of fluid
flush to lubricate and cool the bearings. Cantilever
pumps are of the overhung shaft type and do not
contain any bearings below the mounting plate.
pump installatiOn
1) Inspect pump and any accessories packed
with the unit to assure no damage has
occurred during transit.
MOTORS ARE SHIPPED SEPARATELY
AND SHOULD ALSO BE INSPECTED.
Install the pump assembly in the pit before
mounting the motor to prevent damage.
2) WHEN HANDLING THE PUMP UNIT, IT IS
VERY IMPORTANT TO PICK UP THE UNIT
BY THE TOP.
A rope or sling should be attached to the
bearing pedestal (Item 81) or the mounting
plate (Item 89). Serious damage may result
if the unit is picked up by the column shaft
(Item 91) or discharge pipe (Item 95). The
pump assembly must be lowered carefully
into the pit. Care must be taken to guide the
pump as it is lowered into the pit to avoid
striking the sides.
3) When the mounting plate is resting in the
proper position, check the level of the plate,
and shim if necessary to level the unit. The
pump shaft must be vertical to avoid a
bending stress on the shaft column, and to
avoid bearing damage during operation.
Check the shaft column (Item 91) with a
level to be sure the unit is straight and
plumb.
4) Bolt down the mounting plate, and be sure it
is supported on all four sides.
there should
be a minimum of 4 to 12 inches between
INSTALLATION 5500 SERIES AND 7500 SERIES PUMPS
the bottom of the suction strainer, and
the bottom of the tank of pit.
For higher
flow pumps, this clearance may be specified
as greater; check your outline drawing.
5) Be sure the source of lubrication to the line
bearings on 5500 Series vertical pumps has
been connected if an external flush source
is required. Check all fittings at the line
bearings to be sure no damage has
occurred during shipment.
6) Connect level control, if the pump is so
equipped.
impeller adjustment - all mOdels
ALL MODELS ARE PREADJUSTED BEFORE
LEAVING THE FACTORY. CHECK TO SEE IF
SHAFT TURNS FREELY BY HAND. IF NO
BINDING IS NOTED, NO FURTHER ADJUST-
MENT IS NEEDED. IF BINDING IS NOTED,
FOLLOW ADJUSTMENT PROCEDURE BELOW.
NEVER ADJUST IMPELLER WITH COUPLING
CONNECTED.
The impeller must be adjusted with the pump
mounted in the vertical position.

1) Loosen bearing cap set screw (Item 12A).
2) Loosen clamping screw in adjusting collar
(Item 66).
3) Slowly rotate adjusting collar counterclock-
wise while pushing down on shaft, and rotate
shaft until you feel the impeller touch the
casing face.
4) Place a dial indicator on the end of the shaft.
Rotate the collar clockwise (CW), raising the
shaft to the clearance specified in Table 1.
NOTE: For “Quick Field” adjustment, rotate
the collar 90° clockwise, while securing the
shaft.
5) Re-lock adjusting collar clamping screw
(Item 66).
6) Tighten set screw (Item 12A).
