DESIGNED FOR OPTIMUM BEARING LIFEBearings are a critical component in any sump pump. Fybrochas focused on the design of bearings in the Series 5500Vertical pump in order to optimize their performance, whileensuring long life and trouble-free operation. Fybroc’s uniquedesign approach also incorporates a number of key featureswhich greatly simplify maintenance.THRUST BEARINGFybroc Series 5500 Vertical pumps utilize a grease-lubricatedball 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 ofstandard, “off-the-shelf” C-face motors.SPLIT SLEEVE BEARINGSFybroc’s unique sleeve bearing is clamped to the column withfiberglass boltingOne of the Series 5500 pump’s most innovative featuresis its axially split sleeve bearings. These Teflon and carbonfilled polyphenylene sulfide (PPS) bearings, which are held inplace by an externally mounted split fiberglass bearing holderas shown in the photographs at left, can be replaced conveniently without dismantling the entire pump (including theshaft). The bearing holders are drilled to provide necessaryflush liquid to the grooved bearings. Sleeve bearings aremounted at a maximum spacing of 30 inches (762 mm) toensure that the pump operates well below its first critical speed.LOWER SLEEVE BEARINGThe pump sleeve bearing has received special attention sinceit carries the greatest amount of radial load in the pump. TheFybroc Series 5500 pump utilizes a Teflon and carbon-filledPPS lower bearing that is grooved to ensure generous lubrication. This bearing, which is locked into position in the pumpcover by a fiberglass key and a polypropylene snap ring, islonger than the upper bearings for increased surface area. Theresulting lower unit loading substantially improves bearing life.PUMP COLUMN Bearings and holders are split to permitinspection without pump (including the shaft)disassembly Bearings are easily removed from the fiberglass bearing holdersThe Fybroc Series 5500 features a large diameter columnwhich, because of its moment of inertia, stiffens the entirepump assembly and reduces deflection loads on the columnbearings. Another aspect of the column’s unique design is thelocation of the sleeve bearing holes in the column. They arepositioned so that in the event of shaft wear, the column canbe inverted end-for-end to allow the bearings to run on unwornsurfaces of the existing shaft, thereby extending the useful lifeof the shaft and reducing costly downtime.DUAL VOLUTEAnother important distinction of the Fybroc Series 5500 is theuse of dual volute casings. Radial thrust from the pumpimpeller, which can highly load the lower bearing, is greatlyreduced by this feature. Fybroc uses double volute casings ineleven of its larger pump sizes where, typically, radial thrustloads are higher. See chart on page 9, Casing Data Volute.3

DESIGN FEATURES OF THE SERIES 5500 VERTICAL PUMPThe Fybroc Series 5500 Vertical pump has been designedto provide exceptional structural integrity, excellentcorrosion-resistance, and dependable service in the mostdifficult chemical or waste sump environments. The uniquefeatures described on these pages provide the ultimate inoperating life and ease of maintenance.45632174

LARGE DIAMETER COLUMN, fitted with heavy dutyClass 150 flanges on each end, stiffens the pumpassembly to extend bearing life. The column can beinverted end-for-end thereby offsetting existing bearingports and extending shaft life.4. HEAVY-DUTY BEARING PEDESTAL is of cast ironconstruction to rigidly support the pump column, thrustbearing and motor, and is protected from externalcorrosion by a polyester thermosetting powder coating.5. SLEEVE BEARING FLUSH lines are arranged to simplifyfield connection of external flush liquid. When theprocess liquid is free of solids, flush lines can beconnected to the pump discharge for lubrication. Inaddition, short setting pumps can be configured with aninternal cover flush to supply lubrication to the lowersleeve bearing.11126. FIBERGLASS MOUNTING PLATE is of heavy dutyfiberglass and of appropriate thickness and size tosupport the pump and motor. Mounting plates areavailable in both standard and custom configurations.7.
