FONGS NATIONAL ENGINEERING CO.LTD Equipment We Repair — By Category
FONGS NATIONAL ENGINEERING CO.LTD Product Lines We Repair
Our engineers are trained on the full FONGS NATIONAL ENGINEERING CO.LTD product range. Below are the major product families we service.
Fongs Centrifugal Pump Series
End-suction and split-case centrifugal pumps for high-head, high-capacity applications. Common failures include impeller cavitation damage, seal leakage, and bearing wear caused by abrasive particle ingress and operating beyond rated parameters.
Fongs Submersible Motor Units
Submerged three-phase and single-phase motors for deep-well irrigation, water supply, and sewage applications. Typical faults include stator winding insulation breakdown, rotor cage fractures, and bearing corrosion from prolonged groundwater exposure.
Fongs Soft-Starter Control Panels
Electronic soft-start modules reducing inrush current and mechanical stress on pump impellers and motors. Repair issues centre on thyristor gate-drive failures, control transformer burnout, and thermal sensor malfunctions under high ambient heat.
Fongs Pressure Gauge and Flow Instrumentation
Analogue and digital pressure transducers, flow meters, and vacuum gauges integrated into Fongs pump discharge and suction lines. Failures include diaphragm rupture, electrical connector corrosion, and calibration drift in industrial chemical environments.
Fongs Motor Control Relay Units
Overload relays, contactor assemblies, and reversing starters for pump motor protection and automation. Common defects include contact pitting, coil insulation failure due to moisture ingress, and loose terminal connections causing intermittent tripping.

Common FONGS NATIONAL ENGINEERING CO.LTD Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in FONGS NATIONAL ENGINEERING CO.LTD equipment arriving at our workshop.
- ✓Fongs submersible motor stator winding failure and burnout — Prolonged groundwater ingress through cable glands and motor terminal box seals, combined with high ambient temperature (40-50°C in Indian summers), causes rapid insulation degradation. Single-phasing due to loose contactor contacts exacerbates thermal stress.
- ✓Centrifugal pump impeller cavitation pitting and blade erosion — Fongs pump cavitation occurs when suction-side pressure drops below vapour pressure, common in high-altitude installations, long suction lines, or when operating above 110% rated capacity. Abrasive suspended solids accelerate pitting damage.
- ✓Soft-starter thyristor gate-drive circuit failure and no soft-start engagement — Fongs soft-starter control boards suffer thyristor gate-drive transformer burnout under sustained inrush current spikes (especially in sugar mills with frequent emergency pump starts). Moisture ingress into terminal blocks also causes gate-signal loss.
- ✓Pressure transducer signal loss and gauge read errors in Fongs systems — Fongs pressure gauges and transducers fail due to diaphragm rupture from water hammer events, corrosion of copper sensing lines in high-chloride groundwater, and loose 4-20 mA connector pins at the control panel after thermal cycling.
- ✓Fongs motor contactor coil insulation breakdown and chattering contacts — In dusty industrial environments (flour mills, chemical plants), Fongs contactor coil insulation accumulates conductive dust, reducing coil resistance and causing voltage imbalance. Loose riveted contacts develop micro-arcing and pitting.
- ✓Soft-starter thermal overload relay nuisance tripping in hot season — Fongs soft-starter thermal sensors (bimetallic or PTC thermistor) are calibrated for 40°C ambient but experience 50-55°C in Indian summer industrial plants. Combined with high pump discharge pressure and motor slip current, the relay trips prematurely even under normal load.

Frequently Asked Questions — FONGS NATIONAL ENGINEERING CO.LTD Repairs
Do you repair Fongs National Engineering pumps and motors throughout India?+
Yes. Synchronics provides PAN-India repair for all Fongs National Engineering Co. Ltd. centrifugal pumps, submersible motors, soft-starters, and control systems. We offer door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata, and 100+ tier-2 cities. All repairs are completed in our Vadodara, Gujarat facility and tested before return shipment.
What is the typical turnaround time for Fongs submersible motor stator rewinding?+
Synchronics completes Fongs submersible motor stator rewinding in 5-7 working days for 1.5 to 7.5 HP units. This includes insulation testing, megger checks, and high-voltage proof testing. Emergency rewinding (3-day turnaround) is available for critical irrigation and water supply applications; contact our duty engineer for availability. Once rewound, we guarantee 2 years of workmanship.
My Fongs pump soft-starter shows F1 or F2 error codes. What does this mean?+
Fongs soft-starter F1 code typically indicates gate-drive circuit failure in the thyristor section, often due to transformer burnout or optocoupler failure. F2 code signals overload or over-temperature condition. Synchronics diagnoses both faults using specialised thyristor testing equipment, replaces faulty power modules, and recalibrates the overload relay. We test the entire soft-starter under simulated load before dispatch.
Can Synchronics repair Fongs pressure transducers and calibrate them to site-specific ranges?+
Yes. Synchronics repairs and recalibrates Fongs pressure transducers using laboratory-grade pressure test stands accurate to 0.1% FS. We can reprogram output ranges (e.g., 0-10 bar to 4-20 mA or 0-1 VDC) and verify linearity across the full scale. If the diaphragm or sensing element is damaged, we replace it with genuine or equivalent parts and issue a new calibration certificate.
Why is my Fongs centrifugal pump cavitating even though it was working fine last season?+
Cavitation in Fongs pumps often develops gradually due to increased suction-line friction (clogged strainers), higher ambient temperature reducing water vapour pressure, or erosion of impeller inlet edges. Synchronics performs suction-line inspections, calculates NPSH margin, and visually inspects the impeller for blade pitting. If cavitation damage is light, we can re-machine the impeller; heavy damage requires replacement. We also recommend installing a suction-lift gauges to monitor pressure.
How do I send my FONGS NATIONAL ENGINEERING CO.LTD 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 FONGS NATIONAL ENGINEERING CO.LTD 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 FONGS NATIONAL ENGINEERING CO.LTD 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 FONGS NATIONAL ENGINEERING CO.LTD 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.
