VOITH Equipment We Repair — By Category
VOITH Product Lines We Repair
Our engineers are trained on the full VOITH product range. Below are the major product families we service.
VOITH Hydraulic Couplings (VH-Series)
Hydrodynamic transmission systems for soft-start and load isolation in conveyor belts, crushers, and fans. Common faults include fluid pressure loss, internal wear causing slip, temperature sensor failures, and electronic control module malfunction under high-load cyclic operation.
VOITH Torque Converters (VOITHMATIC)
Fluid coupling systems for cement mills, sugar crushers, and mining conveyors requiring vibration damping and gradual acceleration. Typical failures include fluid degradation codes, solenoid valve stiction, pressure regulator drift, and PLC communication loss with pump speed sensors.
VOITH Gearbox Electronic Control Units (ECU-G)
Integrated drive controllers for helical and planetary gearboxes in cement kiln drives, sugar mills, and mine hoists. Common repair issues include encoder failure, load-sharing imbalance, thermal shutdown false alarms, and CAN-bus communication faults between drive units.
VOITH Turbo Converter Electronic Module (TVEC)
Advanced electronic control for torque converter lock-up and bypass regulation in heavy-duty mills and crushers. Repair demands include analog input signal conditioning failures, solenoid driver transistor breakdown, firmware corruption, and proportional valve drift compensation issues.
VOITH DIWA Gearbox Drive Interface
Electronic interface unit connecting VOITH automatic gearboxes to industrial machinery and PLC systems. Typical faults include J1939 network timeout, shift solenoid coil failure, pressure sensor signal loss, and temperature compensation algorithm errors under ambient extremes.
VOITH VoFluid Pump Speed Control (VSC-Module)
Closed-loop pump speed and pressure regulation for variable-displacement hydraulic circuits in mills, crushers, and compressors. Common failures include proportional spool valve hysteresis, pressure transducer calibration drift, temperature compensation errors, and closed-loop oscillation under load transients.

All-India Service
Couriered repairs accepted from any city in India — Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common VOITH Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in VOITH equipment arriving at our workshop.
- ✓VOITH Hydraulic Coupling Temperature Runaway — Internal fluid bypass leakage or worn internal piston causes uncontrolled slip and friction-generated heat exceeding sensor threshold. Thermal cutoff relay fails to trip due to corroded contacts or faulty temperature compensation logic in the control PCB.
- ✓VOITH Torque Converter Solenoid Valve Stiction — Hydraulic fluid degradation (common in tropical Indian climates) causes varnish and sludge accumulation on solenoid spool. Proportional valve becomes sluggish, causing erratic pressure modulation and delayed load response in cement mills running 24/7 cycles.
- ✓VOITH ECU-G Encoder Signal Dropout — Incremental rotary encoder on gearbox output shaft experiences bearing wear or connector corrosion in wet or vibration-prone installations. Signal loss causes load-sharing imbalance between parallel motor drives and false fault codes E04, E12 on the display.
- ✓VOITH TVEC Solenoid Driver MOSFET Failure — High-current solenoid coils in harsh mill environments cause inductive kick transients that degrade the gate-oxide of power MOSFET devices over 3-5 years. Single transistor failure cascades to converter lock-up failure, leaving gearbox in neutral or uncontrolled slip.
- ✓VOITH DIWA J1939 Network Timeout Error — CAN-bus termination resistance degradation, loose connectors in plant vibration environment, or firmware version mismatch between gearbox ECU and plant PLC cause communication dropouts. Gearbox enters limp-home mode or refuses to shift under load.
- ✓VOITH VSC Proportional Pump Control Oscillation — Proportional valve spool hysteresis and closed-loop PID gain settings optimized for cold-start conditions cause hunting oscillations at steady-state under warm ambient. Plant pressure gauge fluctuates ±20 bar, causing product flow variations in sugar mills and mineral crushers.

Yes. Synchronics stocks genuine VOITH internal seals, piston rings, bearing assemblies, and spring kits for VH-Series and VOITHMATIC coupling repair. We also supply compatible non-OEM alternatives certified for Indian operating temperatures (up to 50°C ambient). All internal components are replaced during major overhaul; we provide fluid analysis and recommend complete fluid replacement to restore performance and thermal stability.
How do I send my VOITH 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.
What is the cost of repairing a VOITH 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 VOITH 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 VOITH 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.
