At Frontline Industries, pump overhaul
takes on a completely new meaning. When we
overhaul a pump,
we put our heart in every repair.A typical overhaul of
a Single Stage Horizontally Split Centrifugal Pump will
include:
- Complete disassembly of unit
- Sandblast the upper and lower casing
- Meticulously clean and dimensionally check the bearing
housing
- Glass bead the impeller
- Manufacture and Install a new Stainless Steel Shaft
- Manufacture and Install New Bronze Sleeves
- Assemble rotor and check for “run-out” at
the impeller O.D., the wear rings,
the sleeves and
at the coupling side
- Dynamically balance rotor to operating speed (with
the coupling hub installed
whenever possible)
- Restore wearing ring clearances to original specifications
- Retrofit the casing rings
with “O”-Rings
so as eliminate water recirculation on
the outside
of the wear rings
- Chase all the threaded holes in
the casings including the threaded holes
for the jacking screws
- Assemble the pump with new high
quality precision bearings, upgraded mechanical seals,
properly sized gaskets, nuts, bolts and fittings
- Hydro-Test pump to 1-1/2 times the operating pressure
