Keep large industrial repairs in the Western Cape
Long-distance repairs add work at a time when your team already has a breakdown to manage. You may need to arrange specialist transport, cranes, packaging, insurance, loading, and unloading. Your engineers may struggle to inspect the dismantled equipment or discuss the findings with the repair team in person. Any additional work can delay approval while the unit sits hundreds of kilometres away.
CAW’s Cape Town facility has 3,000 m² of workshop space.
Overhead cranes can lift equipment weighing up to 40 tonnes.
Overhead cranes can lift equipment weighing up to 40 tonnes, while large workshop entrances provide access for substantial motors, generators, and alternators. Smaller cranes and crane trucks handle lighter equipment.
Keeping the work local gives you:
- Less long-distance transport
- Fewer equipment handovers
- Easier access to the repair team
- Faster approval of additional work
- Better visibility while the repair is under way
- One local contact for the complete job
This matters most when the equipment is large, specialised, difficult to replace, or holding up an essential part of your operation. Get it repaired by local teams to save time, money, and uptime.
One team can handle the electrical and mechanical work
A failed motor often has more than one problem. The winding may have burnt out, but the motor may also have worn bearings, a damaged shaft, poor balance, contaminated insulation, or misalignment. A pump may arrive with a failed motor, worn mechanical parts, damaged seals, and an impeller that needs attention. Repairing one fault and ignoring the rest can lead to another breakdown.
At CAW, our electrical and mechanical teams work on the same job. Depending on the condition of the equipment, the repair may include:
You deal with one repair partner throughout the process. You do not need to move the equipment between separate winding, engineering, balancing, and testing suppliers.
We find the cause before we repair the damage
A burnt winding tells you what failed. It does not always tell you why it failed. Overloading, poor ventilation, moisture, contamination, damaged bearings, voltage problems, misalignment, and vibration can all damage a motor. Problems in the driven equipment can also place extra strain on it.
Our technicians inspect the complete unit before they finalise the repair scope. They check the electrical condition, mechanical components, insulation system, rotor, stator, bearings, shaft, and signs of contamination or overheating.
This helps your team understand:
- What failed
- What caused the failure
- Which components need repair
- Which parts need replacement
- Whether the equipment remains worth repairing
- Which tests the unit needs before it returns to service
A clear assessment also helps you compare the repair cost with the price, availability, and lead time of replacement equipment.
Motor rewinding in Cape Town
A motor rewind can bring a specialised or expensive motor back to life, when replacement would take too long or be too expensive. The quality of the rewind depends on every stage of the job. The technicians must remove the old winding carefully, inspect the motor core, manufacture the correct coils, install them properly, apply insulation, treat the winding, and test the finished motor.
CAW completes this work in Cape Town.
Our facility includes:
- A burnout oven for removing old windings and varnish
- Baking ovens for drying and preparing larger stators and rotors
- A Vacuum Pressure Impregnation system
- Facilities for manufacturing field and interpole coils
- Sandblasting bays for removing rust, paint, grease, and corrosion
Vacuum Pressure Impregnation, or VPI, draws insulating varnish deep into the winding. This strengthens the insulation and helps protect the motor against moisture, dirt, and contamination.
If you need a Cape Town company that specialises in coil manufacture and rewinding services, you can easily bring the electrical repair, mechanical work, balancing, and testing to our one local facility.
Shaft repairs, machining, and balancing
Mechanical wear can shorten the life of a newly repaired motor. A bent shaft, worn bearing area, damaged housing, or unbalanced rotor can cause vibration, noise, heat, and further bearing damage. The vibration may also affect the pump, gearbox, fan, or machine connected to the motor.
300-ton press
CAW uses a 300-ton press to remove broken shafts from rotors.
Mechanical repairs
Our engineering team can assess and repair worn mechanical components within our workshop capacity.
Computerised balancing
We also use a computerised hard-bearing balancing machine for suitable rotors. The machine produces printed reports, giving your team a record of the balancing results.
Test the equipment before it returns to your site
You need to know that repaired equipment can do its job. A basic run test may confirm that a motor turns, but it may miss problems that only appear under load. Electrical weakness, vibration, core damage, excessive heat, and pump performance issues can remain hidden without the right tests.
CAW has the best electric motor testing facility in Cape Town. We test motors, generators, alternators, and pumps at our Cape Town facility and on client sites where required.
Available motor tests include:
- Load testing
- Core loss testing
- Motor circuit evaluation
- Winding analysis and surge testing
- Vibration analysis
- Thermography
- Polarisation index testing
- Locked-rotor testing
- Submersible pump testing
The load-testing facility can simulate working conditions and measure torque and power output. CAW can test suitable motors at 50 Hz and 60 Hz, with full-load testing up to 450 kW in both directions. Test reports give your engineers a clear record of the results. They also provide useful baseline information for future maintenance and condition monitoring.
Industrial pump repairs in Cape Town
A failed pump can stop production, drainage, cooling, water transfer, wastewater treatment, irrigation, or chemical processing. The problem may involve the pump, its motor, or both. Bearings, seals, shafts, impellers, casings, coatings, alignment, and electrical windings may all need inspection.
CAW repairs and refurbishes centrifugal, submersible, vacuum, and other industrial pumps within our local workshop capacity.
We coordinate the motor work, mechanical repairs, machining, balancing, reassembly, and testing.
Our submersible pump testing facility measures the performance of suitable pump and motor sets before they return to site.
This gives municipalities, treatment plants, and industrial operators evidence that the repaired pump can deliver the required output.
Repair support for Western Cape industries
Different industries place different demands on motors, pumps, generators, and alternators. We consider where the equipment works, what it drives, and what conditions it faces.
Manufacturing and processing
Motors keep conveyors, mixers, fans, compressors, pumps, and production lines moving. A small motor can stop a large part of the plant when it drives a critical process. Local repairs allow your maintenance team to inspect the equipment, speak directly to the repair team, and plan the return around production requirements. CAW also supports planned shutdown work, routine maintenance, testing, and fault finding before a breakdown stops production.
Mining
Mining equipment works under heavy loads and faces dust, dirt, heat, vibration, and abrasive material. CAW repairs motors used on conveyor drives, pumps, crushers, mills, and feeders. Our field service team can also inspect and work on fixed plant equipment at your site. This allows us to look beyond the failed motor and check whether the load, alignment, installation, or connected equipment contributed to the problem.
Marine and fishing
Large vessel motors, alternators, and generators can be costly and difficult to transport inland. CAW’s lifting capacity, large workshop access, and 60 Hz load-testing capability allow us to handle suitable marine equipment in Cape Town. We support fishing vessels, ships, rigs, and other maritime operations. We can also repair relevant flameproof and non-sparking motors within our approved certification scope.
Water and sanitation
Municipalities and industrial water users depend on pumps for water production, transfer, sewage collection, and treatment. These pumps often run for long hours in wet, dirty, or corrosive conditions. CAW is one of the best pump repair companies in Cape Town. We repair and rebuild motors and pumps used in water and sanitation systems. We also test suitable submersible pump sets before they return to service.
Petrochemical operations
Petrochemical plants rely on pumps, compressors, generators, turbines, and motors that often run continuously. CAW provides inspections, coil manufacturing, rotor and stator rewinds, mechanical repairs, and refurbishment for electrical rotating equipment used in these environments. Where hazardous-area certification applies, we confirm the motor type and required repair scope before work begins.
Defence and commercial maritime
CAW repairs and overhauls motors, generators, and alternators for defence and commercial maritime clients. Our services include workshop repairs, installation, maintenance, and on-site support.
Rail and renewable energy
Rail and renewable energy operations use specialised motors, generators, alternators, coils, and other rotating equipment. CAW handles traction motors and related equipment within its workshop capabilities. We also provide diagnostics, winding work, mechanical repairs, balancing, and testing for suitable renewable energy equipment.
On-site repairs and emergency breakdown support
Some jobs need to start at your plant, vessel, pump station, mine, or workshop. CAW provides on-site fault finding, motor circuit analysis, predictive maintenance, troubleshooting, and repairs through its field service team and mobile workshop.
We can assess the fault on-site, help with removal where required, complete the workshop repair, and support installation or commissioning.
