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.

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.
