AJAX VERTICAL CENTRIFUGAL SUMP PUMP REPAIR

CASE STUDIES

CUSTOMER:

JOB OVERVIEW:

This AJAX sump pump was vibrating badly and significantly down on performance. The pump is critical to keep water levels from rising and flooding a switchroom.

CHALLENGES

  • Pump has never been overhauled so was in poor condition.

  • The issues have developed in the wet season so a quick turn around was needed.

  • Bearing housing bolts had broken, damaging the machined spigot. Coupling bolts were broken and obsolete.

  • Bottom journal bearing was worn and needed replacement.

  • Impeller to casing wear ring clearance was excessive.

  • Large solids were able to enter the impeller eye and get caught due to a damaged suction screen.

  • Motor bearings were noisy, casing was heavily corroded.

  • Lead time on replacement pump (8 weeks) was unacceptable and like for like replacements no longer available

SOLUTION:

  • Machine and balance impeller.

  • Machine and fit casing wear ring.

  • Weld repair of bearing lantern and re-machine spigot. 

  • Thordon journal bearing.

  • New high tensile coupling bolts to suit existing cone ring coupling.

  • New WEG EXD electric motor.

  • New 316 SS suction screen.

  • Epoxy ceramic internal coating.

  • 2Pack epoxy external coating.

 

RESULT:

  • Pump was repaired, re-installed and commissioned successfully within 2 weeks from removal.

  • Vibration is low and pump output is as good as new.

  • Pump was repaired for less than 50% of the cost of an equivalent replacement and in a 1/4 of the time.
