Centrifugal Pump Repair

Expert restoration to full performance, minimizing downtime and cost.
Centrifugal pump repair by EKG Malaysia involves a systematic process to diagnose failures, restore hydraulic efficiency, and correct root causes—extending pump life and protecting your operations from unexpected stoppages. We repair all centrifugal pump types, from small HVAC circulators to large industrial process pumps.

Common Failures We Repair:

• Mechanical Seal & Bearing Failure: The most frequent repairs, often caused by misalignment, dry run, or cavitation.

• Cavitation Damage: Pitted impellers and volutes due to insufficient NPSH.

• Wear Ring & Impeller Erosion: From abrasive fluids or operation far from BEP.

• Shaft Deflection or Breakage: Due to hydraulic imbalance, corrosion fatigue, or bearing seizure.

• Casing Damage: Cracks or wear from corrosion, erosion, or water hammer.

Our Certified Repair Process:

1. Diagnosis & Disassembly

• On-site or workshop inspection to identify visible issues.

• Complete, careful disassembly, cataloging all components.

2. Cleaning & Detailed Inspection

• Ultrasonic cleaning of all parts.

• Dimensional inspection against OEM drawings (shaft runout, bore sizes, clearances).

• Non-Destructive Testing (NDT) like dye penetrant for cracks if needed.

3. Root Cause Analysis (RCA)

• We determine why the pump failed, not just what failed.

• Provide an RCA report with recommendations to prevent recurrence (e.g., system changes, alignment procedures).

4. Precision Repair & Reconditioning

• Shaft Work: Straightening, machining, metal spray (welding), grinding, or replacement.

• Hydraulic Component Repair: Impeller rebuilding (welding and dynamic balancing to ISO G6.3/G2.5), wear ring replacement, volute repair or metal stitching.

• Bearing Housing Restoration: Line boring or sleeving to restore perfect fits.

• Casing Repair: Welding, machining, or epoxy repair for castings.

5. Reassembly & Testing

• Precision Alignment of all internal components.

• Static Pressure Test: Hydrostatic test of casing.

• Mechanical Run Test: Vibration and temperature analysis under no-load conditions.

• Performance Test: When possible, we test to original pump curve to verify restored capacity and efficiency.

6. Re-installation & Commissioning

• Final laser alignment to the driver at your site.

• Start-up supervision and performance verification.

Repair vs. Replace Guidance:
We provide an honest assessment. If repair costs exceed ~65% of a new pump's price or the core is obsolete, we recommend replacement.
