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:

1. Complete disassembly of unit

2. Sandblast the upper and lower casing

3. Meticulously clean and dimensionally check the bearing housing

4. Glass bead the impeller

5. Manufacture and Install a new Stainless Steel Shaft

6. Manufacture and Install New Bronze Sleeves

7. Assemble rotor and check for “run-out” at the impeller O.D., the wear rings,
   the sleeves and at the coupling side

8. Dynamically balance rotor to operating speed (with the coupling hub installed
   whenever possible)

9. Restore wearing ring clearances to original specifications

10. Retrofit the casing rings with “O”-Rings so as eliminate water recirculation on
    the outside of the wear rings

11. Chase all the threaded holes in the casings including the threaded holes
    for the jacking screws

12. Assemble the pump with new high quality precision bearings, upgraded mechanical seals, properly sized gaskets, nuts, bolts and fittings

13. Hydro-Test pump to 1-1/2 times the operating pressure
