Dredge Pump Overhauling & Refurbishment

We restore the efficiency of heavy-duty slurry and sand pumps through precision reconditioning of high-wear components.

• Impeller & Volute Repair: Inspection of impeller wear every 500 hours; gas-shielded welding and self-fluxing alloy powder spraying are performed to rebuild worn profiles.
• Casing Maintenance: Repairing single and double-shell pump casings using wear-resistant alloy casting blocks or specialized volute coatings.
• Bearing & Shaft Protection: Reconditioning of pump and thrust bearings, and electroplating of shafts to resolve corrosion or fretting.
• Seal Integrity: Upgrading to double mechanical seals or packed glands with pressurized clean water flush systems for maximum reliability in harsh slurry conditions.

Coupling & Drive Train Services

The connection between the motor/engine and the pump is critical for torque transfer and vibration management.

• Coupling Overhaul: Dismantling and overhauling claw couplings, including marking flanges for correct reassembly and replacing worn elastic elements.
• Precision Alignment: Using laser alignment tools to ensure perfect pump-to-driver alignment, reducing bearing heat and preventing premature shaft failure.
• Balancing: Dynamic balancing of the entire rotor assembly (ISO 1940 G6.3 grade) to eliminate harmful vibrations during operation.
