Comprehensive workshop machinery and testing standards.
Our Lusaka workshop is fully outfitted with digital temperature-controlled ovens, VPI systems, dynamic balancing rigs, laser alignment gear, and specialized core testing equipment.
Electric Induction Motor Rewinding & Overhaul
Winding failure due to thermal overload, voltage surges, or VFD (Variable Frequency Drive) spikes is the leading cause of induction motor breakdown. We rebuild your electrical stator from the inside out with controlled insulation burn-off, inverter-duty wire, VPI varnishing, and micrometric mechanical overhauling.
- Controlled Burn-Off Pyrolysis
- Vacuum Pressure Impregnation (VPI)
- Dynamic Balancing (ISO Standards)
- Micrometric Journal & End-Bell Machining
- Full-Load & Surge Comparison Testing
Industrial Pump Motor Rewinding & Repair
We provide comprehensive, engineering-grade industrial pump motor rewinding and repair services designed to withstand the demanding conditions of water treatment, chemical processing, manufacturing, and HVAC infrastructure. Our certified technicians restore submersible, centrifugal, vertical turbine, and positive displacement pump motors to OEM or better specifications—delivering up to 50% cost savings over buying new equipment while heavily reducing plant downtime.
- Waterproof & Submersible Insulation
- Dynamic Impeller & Rotor Balancing
- Shaft Re-sleeving & Journal Machining
- Tungsten/Silicon Carbide Seal Lapping
- Pressure & Hydrostatic Chamber Testing
Transformer Rewinding & Refurbishment
Dielectric breakdown, thermal aging, and short-circuit mechanical stresses degrade internal windings over time. We completely reconstruct your transformer's electrical core with oxygen-free copper, Class H/Nomex insulation, deep vacuum dehydration, and complete mechanical gasket/seal overhauling.
- Core Loss & Hot-Spot Electromagnetic Testing
- Vacuum Thermal Dehydration Oven Baking
- Insulation Resistance & Turns Ratio Testing
- Buchholz & Protection Calibration
- Radiator Chemical Flushing & Bushing Upgrades
Diesel Generator Rewinding & Service
From emergency standby generators to continuous baseload units, our engineering team executes core loss testing, main rotor and exciter stator rebuilding, laser shaft alignment, and AVR calibration ensuring seamless instantaneous voltage response.
- Exciter Diode & Varistor Testing
- Laser Coupling Alignment
- Full Stepped Load-Bank Testing
- AVR Voltage Regulation Tuning
- Bearing Clearance & Anti-Friction Overhaul
Precision testing before machine dispatch.
Every unit restored in our Lusaka facility is subjected to rigorous electrical and mechanical verification protocols.
Class H & VPI Impregnation
Inverter-duty spike-resistant magnet wire paired with Class H Nomex insulation and deep vacuum varnishing eliminates internal air pockets, resisting moisture and thermal surges.
Dynamic Rotor Balancing
Precision 2-plane dynamic balancing on all rotors, impellers, and slip-ring assemblies to prevent structural resonance, premature bearing wear, and mechanical fatigue.
Laser Couplings & Regulation
High-precision laser alignment for engine-to-alternator couplings and sub-second AVR calibration ensuring ±0.5% voltage regulation under stepped load.
