Process Pump Replacement & Sizing — Food Processing Plant
Failed transfer pumps replaced with correctly sized units: duty analysis, NPSH checks, alignment supervision and commissioning.
Client: Confidential client — food manufacturer • Service: Mechanical Engineering
Project overview
A food processing plant at Thika suffered repeated failures of its hot-water and CIP transfer pumps — seal failures, cavitation damage and chronic underperformance that throttled production.
Ventron's investigation showed the installed pumps had been selected for a duty the plant had long outgrown, with suction conditions guaranteeing cavitation. We re-specified the full pump train for actual operating duties.
Client challenge
Production losses were being treated as a maintenance problem — new seals every quarter — when the root cause was hydraulic: pumps operating far off-curve with NPSH available below required at operating temperature.
Ventron solution
We measured actual flows and temperatures, rebuilt the system curves including fouling allowances, and selected end-suction units running near best efficiency with verified NPSH margins. Suction pipework was enlarged at two stations, strainers and air-release provisions corrected, and installation supervised through alignment, grouting and loop testing. Seal life moved from months to years.
Scope of work
- Duty measurement and system-curve reconstruction
- Pump selection with NPSH verification
- Suction pipework modifications
- Installation supervision and commissioning
Engineering deliverables
- Pump datasheets and selection report
- Modified piping isometrics
- Alignment and test records
- Operating envelope and spares list
