Wilo Equipment We Repair — By Category
Wilo Product Lines We Repair
Our engineers are trained on the full Wilo product range. Below are the major product families we service.
Wilo Stratos
Electronically commutated (EC) motor-driven circulating pumps for heating and cooling circuits. Common issues include motor controller failures, impeller bearing seizure, and thermal sensor malfunction due to scale buildup in hard water regions.
Wilo Helix
Multi-stage centrifugal pumps for high-pressure domestic water supply and industrial applications. Repair focuses on mechanical seal wear, impeller damage from cavitation, and bearing housing corrosion in coastal and high-mineral-content water installations.
Wilo TopS
Single-stage centrifugal pumps for water supply, pressure boosting, and industrial circulation. Typical failures include motor burnout from dry-run operation, pump casing fractures under thermal stress, and suction-side cavitation damage.
Wilo SiBoost
Variable-speed pressure boosting pump systems with integrated EC motor and soft-start control. Common defects: pressure switch malfunction, non-return valve leakage, and EC controller PCB degradation from condensation in pump rooms.
Wilo MVIE / MVIL
Submersible sewage and wastewater pump systems for municipal and industrial treatment plants. Repair addresses motor winding insulation breakdown from chemical exposure, mechanical seal degradation, and stainless steel impeller corrosion.
Wilo Planar
In-line pump designs for compact installations in HVAC and industrial systems. Issues include bearing race spalling, shaft deflection under lateral load, and gasket failure in high-temperature applications above 65°C.

Common Wilo Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in Wilo equipment arriving at our workshop.
- ✓EC motor controller failure in Stratos pumps — Wilo's electronically commutated motors rely on solid-state power modules sensitive to thermal cycling and humidity. In Indian monsoon conditions and high-ambient-temperature pump rooms, capacitor degradation and MOSFET burnout occur within 5-7 years of operation.
- ✓Mechanical seal leakage and bearing seizure — Hard water deposits and mineral scaling on Helix and TopS pump seals reduce cooling flow to the seal chamber. Secondary ring stiction develops, shaft seal fails, and bearing races corrode rapidly. Common in Gujarat, Rajasthan, and North India water supplies with >500 ppm hardness.
- ✓Impeller cavitation damage and performance loss — Wilo centrifugal impellers cavitate when suction-side pressure drops below vapour pressure — common when pump suction strainers clog, inlet isolation valves throttle, or system flow exceeds rated capacity. Resulting erosion pits reduce head and efficiency by 15-30%.
- ✓Dry-run burnout and phase imbalance in TopS motor windings — In Indian food processing, pharmaceutical, and textile plants, operator error or failed level switches allow Wilo TopS pumps to run without suction pressure. Motor current rises 2-3x, insulation temperature reaches 180°C, and copper windings fail within minutes. Three-phase power imbalance (unequal voltage on R-Y-B) accelerates burnout.
- ✓Pressure switch and non-return valve malfunction in SiBoost systems — Wilo SiBoost integrated pressure switches use micro-switches exposed to moisture ingress and mineral deposits from water hammer events. Non-return valves become sticky or stuck open due to particulate fouling and scale accumulation, reducing pressure accuracy and system reliability.
- ✓Shaft deflection and bearing housing stress fracture — Planar in-line pumps experience lateral loads from rigid piping connections and thermal expansion stress. Over-torqued flanged connections or unsupported discharge piping induce bending stress on the pump shaft and bearing housings. Casing micro-fractures propagate, leaking water into motor windings.

Frequently Asked Questions — Wilo Repairs
Do you repair Wilo equipment anywhere in India?+
Yes. Synchronics repairs the full Wilo product range — Stratos, Helix, TopS, SiBoost, MVIE/MVIL submersible, and Planar pump systems. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, and all other cities. Repairs and testing are performed at our main facility in Vadodara, Gujarat. Average turnaround is 10-15 working days for standard motor and seal replacements.
How do you handle OEM Wilo spare parts and warranty on repairs?+
Synchronics stocks OEM Wilo mechanical seals, bearing kits, impellers, and EC motor controllers. We source directly from Wilo India and authorised distributors to guarantee compatibility with your specific pump model and serial number. All repaired units are backed by 12 months' warranty on labour and replaced components, excluding external damage or misuse.
What is the average repair cost for a Wilo Stratos or Helix pump?+
Repair costs depend on the fault — bearing and seal replacement typically runs INR 8,000–15,000; motor controller repair or replacement INR 12,000–20,000; full motor rewind INR 18,000–35,000. We provide a detailed quotation after inspection. Many customers find repair 40-60% cheaper than buying new Wilo units, with faster turnaround than OEM service centres.
Can Synchronics repair Wilo pumps with cavitation damage or corroded metal casings?+
Yes. For cavitation erosion on impeller blades, Synchronics uses ceramic composite welding and precision machining to restore aerodynamic surfaces. For external casing corrosion or minor pitting, we apply epoxy repair and stainless steel reinforcement sleeves. Pressure and vibration testing confirm structural integrity. Severe casing fractures may require OEM replacement.
Why do Wilo Stratos pumps fail in Indian climate and hard water?+
Wilo Stratos EC motor controllers are sensitive to monsoon humidity and thermal cycling — condensation corrodes PCB traces and capacitors fail. Hard water (>500 ppm) deposits scale on motor cooling fins, raising winding temperature 10-15°C above nominal. We recommend installing surge protectors on power supply, maintaining pump room ventilation at <80% RH, and descaling seals every 18-24 months. Synchronics provides post-repair descaling guidance for Indian water conditions.
How do I send my Wilo unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a Wilo drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on Wilo repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your Wilo unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
