Centrifugal Pump Mechanical Seal Replacement

Expert, precision replacement to restore leak-free operation and reliability.
Mechanical seal failure is a leading cause of pump downtime. EKG Malaysia provides professional seal replacement services for all centrifugal pump types, using quality parts, proper installation techniques, and root-cause analysis to ensure long seal life and prevent rapid recurrence.

Signs You Need Seal Replacement:

• Visible, continuous leakage at the pump shaft.

• Increased makeup fluid in closed-loop systems.

• Reduced pump performance due to air ingress.

• Seal alarm activation on monitored systems.

Our Professional Replacement Process:

1. Diagnosis & Preparation

• Identify seal type, size, and materials from existing pump/model.

• Conduct root-cause analysis of failure (e.g., dry run, cavitation, misalignment, chemical attack).

• Source the correct OEM-equivalent or upgraded seal.

2. Precision Removal & Inspection

• Safe pump isolation, drainage, and disassembly.

• Careful removal of old seal, noting installation orientation.

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

• Cleaning of seal chamber.

3. Correct Installation

• Verification of seal chamber dimensions and squareness.

• Laser shaft alignment prior to reassembly (critical for seal life).

• Careful installation following OEM procedures—ensuring no damage to seal faces, proper spring compression, and correct setting.

• Use of appropriate lubrication and installation tools.

4. Testing & Commissioning

• Pressure testing of the system if applicable.

• Soft start and monitoring for leaks, vibration, and temperature.

• Verification of proper operation under normal conditions.
