FL Product Lines We Repair
Our engineers are trained on the full FL product range. Below are the major product families we service.
FL Centrifugal Pump Controllers
Dedicated control systems for FL's industrial centrifugal pump ranges. Common faults include seal failure indicators, pressure transducer drift, and flowmeter calibration loss affecting accuracy in pharmaceutical and water treatment applications.
FL Variable Speed Drive Units
Frequency converters designed for FL pump optimization and energy efficiency. Typical repair issues: capacitor degradation in Indian humid climates, IGBT module failures, encoder signal loss, and thermal overload trips in continuous-duty installations.
FL Flow Measurement and Custody Transfer Systems
Precision instrumentation for fluid metering and system diagnostics. Common problems: magnetic pickup coil intermittency, signal conditioning circuit faults, digital display malfunction, and Modbus communication failures in networked control systems.
FL Integrated Pump Skid Assemblies
Complete factory-built systems with pump, motor, controller, and instrumentation pre-assembled. Failure modes include inter-component wiring harness degradation, contactor coil burnout, pressure relief valve leakage, and synchronization errors between pump and drive units.
FL Process Control Interface (FlowNet PLC)
Programmable logic controllers for multi-pump orchestration and real-time monitoring. Typical faults: real-time clock battery failure, SD card corruption, Ethernet port damage, analog input card malfunction, and firmware version incompatibility after updates.

Common FL Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in FL equipment arriving at our workshop.
- ✓FL pump controller seal failure indicator malfunction — Mechanical seal wear in high-temperature or viscous fluid applications triggers the indicator LED, but electrical contact corrosion in the signal relay causes false or absent warnings. This is especially common in Indian chemical plants with high ambient humidity.
- ✓FL variable speed drive capacitor bank explosion risk — Electrolytic capacitors in FL VFD units degrade rapidly in India's tropical and high-humidity environments. Rated voltage drops below safe operating limits within 3-5 years, causing progressive failure of the DC bus and potential explosive venting of the capacitor can assembly.
- ✓FL flowmeter encoder signal dropout under load — Magnetic pickup coils in FL flow measurement systems degrade due to moisture ingress and thermal cycling. Intermittent signal loss causes the PLC to log fault codes E-042 or E-045, halting pump operation and disrupting production in continuous-duty water treatment plants.
- ✓FL PLC real-time clock (RTC) battery depletion — FL FlowNet PLC internal backup batteries have a nominal lifespan of 5-7 years. In Indian manufacturing environments with inadequate facility earth grounding or frequent power interruptions, the RTC battery depletes faster, causing system time loss and timestamp errors in data logging.
- ✓FL integrated pump skid contactor coil burnout — The main contactor coil in FL SkidPro and ChemSkid assemblies burns out due to suppression diode failure allowing back-EMF overvoltage at coil deactivation. Humid coastal Indian environments accelerate diode leakage current and thermal degradation of the coil insulation.
- ✓FL Modbus communication timeout errors on networked pump systems — EMI from adjacent industrial equipment, inadequate twisted-pair shielding in RS-485 wiring, or terminal resistance mismatch in FL PLC Modbus networks cause intermittent frame errors and loss of synchronization between master and slave pump controllers. Production scheduling becomes unpredictable.

Frequently Asked Questions — FL Repairs
Do you repair FL equipment anywhere in India?+
Yes. Synchronics repairs the complete FL product range including pump controllers, variable speed drives, flow measurement systems, integrated skids, and PLC units across all of India. We offer same-day door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Nagpur, and Kolkata. All repairs are completed in our full-service facility in Vadodara, Gujarat, with comprehensive testing before return shipment.
What is the typical turnaround time for FL pump controller repair?+
FL pump controller repairs usually take 5-7 business days from intake to final testing and dispatch. This includes diagnostic verification, component sourcing, bench repair, and simulation testing against your specific operating parameters. Emergency expedited repairs for critical production lines can be completed in 48-72 hours. We provide real-time status updates via email and phone throughout the repair cycle.
Can you repair FL VFD units that show overvoltage or overtemperature fault codes?+
Yes. Synchronics specializes in FL variable speed drive fault resolution. Overvoltage errors typically indicate capacitor bank degradation or DC bus regulation failure. Overtemperature codes often point to thermal sensor malfunction or IGBT heatsink dust accumulation. We perform full electrical analysis, replace failed components using FL-approved equivalents, and conduct extended thermal cycling tests to confirm restoration before returning the drive to your facility.
Do you offer on-site FL equipment commissioning and startup support?+
Yes. After completing repairs of FL integrated pump skids, controllers, or PLC units, Synchronics offers optional on-site commissioning and system startup support across India. Our engineers verify proper integration with your existing pipeline, sensor calibration, and Modbus network configuration. We provide training to your maintenance team on fault diagnosis and routine preventive maintenance specific to FL equipment.
What warranty do you provide on repaired FL equipment?+
All Synchronics FL repairs come with a 12-month comprehensive parts and labor warranty against manufacturing defects and workmanship issues. Extended 24-month warranties are available for critical pump controller and VFD units. Warranty coverage includes replacement parts, diagnostic testing, and remote technical support. We maintain a stock of FL-compatible components to ensure fast warranty claim resolution.
How do I send my FL 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 FL 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 FL 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 FL 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.
