Belzona Facts
The pump unit was identified for potential overhaul while still in service due to reduced output and overheating of the drive motor, a characteristic of reduced hydraulic performance. When the unit was removed and disassembled for inspection, considerable erosion had occurred on the diffuser bowls, which were also badly deteriorated from the effects of nodal growth and corrosion. By utilizing Belzona computer generated overhaul techniques specific to this pump type and its operating conditions, substantial savings in running costs - approximately $55,000/year, coupled with sustained high levels of performance, increased output and long term protection were achieved.
