Design
Features

 

The
Fybroc Series 5500 Vertical pump has been designed
to provide exceptional structural integrity, excellent
corrosion-resistance, and dependable service in
the most difficult chemical or waste sump environments.
The unique features described on these pages provide
the ultimate in operating life and ease of maintenance.

1.
FIBERGLASS CONSTRUCTION for all wetted
parts, except shaft and bolting, in either
vinyl ester or epoxy resins provides tough
corrosion resistance for a wide range of difficult
liquids.
2.
PRECISION-GROUND SHAFT and all wetted
bolting are selected to suit specific applications
and are
typically 316SS, Alloy-20, Titanium or Hastelloy-C.
3.
LARGE DIAMETER COLUMN, fitted with
heavy duty Class 150 flanges on each end,
stiffens the pump assembly to extend bearing
life. The column can be inverted end-for-end
thereby offsetting existing bearing ports
and extending shaft life.
4.
HEAVY-DUTY BEARING PEDESTAL is of
cast iron construction to rigidly support
the pump column, thrust bearing and motor,
and is protected from external corrosion by
a polyester thermosetting powder coating.
5.
SLEEVE BEARING FLUSH lines are arranged
to simplify field connection of external flush
liquid. When the process liquid is free of
solids, flush lines can be connected to the
pump discharge for lubrication. In addition,
short setting pumps can be configured with
an internal cover flush to supply lubrication
to the lower sleeve bearing.
6.
FIBERGLASS MOUNTING PLATE is of heavy
duty fiberglass and of appropriate thickness
and size to
support the pump and motor. Mounting plates
are available in both standard and custom
configurations.
7.
FIBERGLASS BASKET STRAINER, attached
to the casing by fiberglass studs and nuts,
protects the pump casing and impeller against
damage from trash or other debris.
8.
EXTERNAL IMPELLER ADJUSTMENT allows
field setting of impeller-to-casing operating
clearance from above the mounting plate.
9.
THRUST BEARING is easily replaceable
and carries the entire axial thrust load from
pump impeller, allowing use of flexible couplings
and standard, “off-the-shelf”
motors.
10.
VAPOR SEAL protects thrust bearing
from corrosive sump vapors.
11.
AXIALLY-SPLIT BEARINGS, made of Teflon®
and carbon-filled PPS, are grooved to ensure
even lubricant dispersion and are easily replaceable
while the pump (including the shaft) remains
completely assembled.
12.
SPLIT BEARING HOLDERS align the bearings
with the pump column. Molded in fiberglass,
the holders are drilled to supply flush to
the bearings.
13.
REPLACEABLE LOWER PUMP SLEEVE BEARING,
extra-long to reduce unit surface loading,
is grooved PPS like the upper sleeve bearings,
and is secured in the cover by a key and snap
ring.
14.
PUMP COVER is drilled for flush liquid
supply to the lower bearing. A fully-confined
Viton O-ring (optional elastomers available)
seals the cover to the casing.
15.
SEMI-OPEN IMPELLER utilizes rear
pump-out vanes and balance holes to reduce
the load on the axial thrust bearing.
Designed
for Optimum Bearing Life
Bearings
are a critical component in any sump pump. Fybroc
has focused on the design of bearings in the Series
5500 Vertical pump in order to optimize their performance,
while ensuring long life and trouble-free operation.
Fybroc’s unique design approach also incorporates
a number of key features which greatly simplify
maintenance.
  • Fybroc’s
    unique sleeve bearing is clamped to
    the column with fiberglass bolting
  • Bearings
    and holders are split to permit inspection without pump (including the
    shaft) disassembly
  • Bearings
    are easily removed from the fiberglass bearing holders

THRUST
BEARING
Fybroc Series 5500 Vertical pumps utilize a grease-lubricated
ball bearing designed to handle the axial thrust
load generated by the pump impeller. This bearing,
which is easily replaceable without removing the
installed pump, permits the use of standard, “off-the-shelf”
C-face motors.

SPLIT SLEEVE BEARINGS
One of the Series 5500 pump’s most innovative
features is its axially split sleeve bearings.
These Teflon® and carbon-filled polyphenylene
sulfide (PPS) bearings, which are held in place
by an externally mounted split fiberglass bearing
holder as shown in the photographs at left, can
be replaced conveniently without dismantling the
entire pump (including the shaft). The bearing
holders are drilled to provide necessary flush
liquid to the grooved bearings. Sleeve bearings
are mounted at a maximum spacing of 30 inches
(762 mm) to ensure that the pump operates well
below its first critical speed.

LOWER
SLEEVE BEARING
The pump sleeve bearing has received special attention
since it carries the greatest amount of radial
load in the pump. The Fybroc Series 5500 pump
utilizes a Teflon® and carbon-filled PPS lower
bearing that is grooved to ensure generous lubrication.
This bearing, which is locked into position in
the pump cover by a fiberglass key and a polypropylene
snap ring, is longer than the upper bearings for
increased surface area. The resulting lower unit
loading substantially improves bearing life.

PUMP
COLUMN
The Fybroc Series 5500 features a large diameter
column which, because of its moment of inertia,
stiffens the entire pump assembly and reduces
deflection loads on the column bearings. Another
aspect of the column’s unique design is
the location of the sleeve bearing holes in the
column. They are positioned so that in the event
of shaft wear, the column can be inverted end-for-end
to allow the bearings to run on unworn surfaces
of the existing shaft, thereby extending the useful
life of the shaft and reducing costly downtime.

DUAL
VOLUTE
Another important distinction of the Fybroc Series
5500 is the use of dual volute casings. Radial
thrust from the pump impeller, which can highly
load the lower bearing, is greatly reduced by
this feature. Fybroc uses double volute casings
in eleven of its larger pump sizes where, typically,
radial thrust loads are higher.
