Centrifugal Pump Mechanical Seal Repair

Expert restoration of leak-free, reliable sealing performance.
Mechanical seal failure is a primary cause of pump downtime. EKG Malaysia provides professional seal repair services that go beyond simple replacement, focusing on root cause analysis and precision workmanship to prevent recurring failures and extend the service life of your centrifugal pumps.

Common Seal Failure Symptoms We Address:

• Visible, persistent leakage at the pump shaft.

• High water or chemical loss from the system.

• Seal alarm activation on monitored equipment.

• Reduced pump performance due to air ingress.

Our Comprehensive Seal Repair Process:

1. Diagnosis & Root Cause Analysis (RCA)

• On-site or workshop inspection to identify failure mode.

• Determine underlying cause: dry running, cavitation, misalignment, improper installation, chemical attack, or worn bearings.

2. Precision Disassembly & Inspection

• Careful removal of the seal, noting orientation and condition.

• Inspection of shaft/sleeve for scoring, wear, or corrosion. Machining or replacement if required.

• Measurement of seal chamber dimensions for correct fit.

3. Expert Repair & Reconditioning

• Seal Refurbishment: Where possible, regrinding of seal faces (carbon, ceramic, silicon carbide).

• Component Replacement: Supply and fitment of new OEM or high-quality aftermarket seals, O-rings, gaskets, and springs.

• Shaft/Sleeve Restoration: Machining, polishing, or applying protective coatings to restore sealing surfaces.

4. Correct Reassembly & Installation

• Precision Alignment: Laser alignment of pump and motor is performed before seal installation (critical for seal life).

• Clean, Controlled Environment: To prevent contamination of seal faces.

• Proper Setting: Following OEM procedures for spring compression and installation depth.

5. Testing & Commissioning

• Pressure Test: If applicable, to check for leaks.

• Run-in & Monitoring: Supervised start-up to verify leak-free operation and check for abnormal heat/vibration.
