FLOWSERVE Product Lines We Repair
Our engineers are trained on the full FLOWSERVE product range. Below are the major product families we service.
Flowserve Magnetic Bearing Controllers
Advanced active magnetic bearing (AMB) control systems that manage rotor suspension in high-speed centrifugal compressors and pumps. Common repairs include amplifier faults, sensor signal loss, and bias current instability affecting bearing force regulation.
Seal Support System (SSS) Electronics
Condition monitoring and buffer gas/liquid management controllers for dual mechanical seal assemblies. Repairs address pressure transducer failures, solenoid valve control faults, and data acquisition card malfunctions in dual-seal applications.
Flowserve Pump Automation & Instrumentation
PLC-based control modules and local control panels for centrifugal and rotary pump operation. Typical faults include relay failures, analog input card degradation, communication loss, and firmware corruption affecting flow rate regulation.
Predictive Maintenance Modules
Vibration and temperature monitoring systems integrated with Flowserve pump assemblies for bearing and seal health tracking. Common failures involve accelerometer signal dropout, thermocouple failure, and data logger memory corruption.
Flowserve Valve Positioner Electronics
Smart positioner controllers for automated control valves in process pipelines. Repairs focus on transducer calibration drift, solenoid response delays, and pneumatic pressure regulation circuit failures in Indian refinery applications.

Common FLOWSERVE Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in FLOWSERVE equipment arriving at our workshop.
- ✓Magnetic bearing amplifier saturation and bearing collapse — Flowserve AMB controllers lose bias current regulation due to analog power supply failure or controller firmware version mismatch. High-speed rotors lose suspension, causing mechanical contact and catastrophic bearing wear.
- ✓Seal support system pressure transducer signal loss — Flowserve SSS electronics experience 4-20mA sensor signal dropout due to corroded connector terminals, broken signal conditioning board traces, or software communication timeout. Dual mechanical seals lose monitoring visibility.
- ✓PLC communication card failure and pump control loss — Flowserve FLS-PLC modules suffer Ethernet port failure, CAN bus termination resistance drift, or corrupted bootloader firmware from power surges common in Indian industrial environments. Pump automation ceases, forcing manual operation.
- ✓Vibration monitor accelerometer and alarm threshold miscalibration — Flowserve CMS predictive maintenance modules accumulate incorrect vibration baselines due to sensor drift, temperature compensation failure, or analog-to-digital converter nonlinearity. False alarms or missed early fault detection occur in Indian power and petrochemical plants.
- ✓Valve positioner solenoid coil burnout and pressure instability — Flowserve smart positioner electronics deliver continuous energization or overvoltage to proportional solenoid coils due to output stage transistor failure or PWM duty cycle fault. Control valve response becomes sluggish or locks in process lines.
- ✓Controller power supply capacitor dry-out and thermal shutdown cycles — Flowserve magnetic bearing and seal system controllers experience premature electrolytic capacitor degradation in hot Indian environments, causing supply voltage ripple and thermal foldback. Equipment shuts down intermittently during peak load operation.

Frequently Asked Questions — FLOWSERVE Repairs
Do you repair Flowserve equipment anywhere in India?+
Yes. Synchronics repairs the full Flowserve product range — magnetic bearing controllers, seal support systems, PLC automation modules, valve positioners, and predictive maintenance modules. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, and all other cities. Same facility in Vadodara, Gujarat. Most Flowserve repairs completed within 5-7 working days.
What is a magnetic bearing controller and why does Flowserve equipment need specialized repair?+
Flowserve magnetic bearing controllers (MBC series) actively suspend high-speed pump or compressor rotors using electromagnetic force, eliminating mechanical contact bearings in applications exceeding 20,000 rpm. These controllers require precision analog tuning, sensor calibration, and firmware expertise that generalist repair shops lack. Synchronics maintains Flowserve amplifier test benches and has restored MBC-3000/4000 units in 300+ Indian industrial installations.
Can you repair Flowserve seal support system (SSS) electronics with dual mechanical seal monitoring?+
Yes. Flowserve SSS-100 and SSS-200 controllers manage dual seal buffer pressure, detect seal face wear, and alert operators to impending failure. Synchronics restores SSS transducer channels, recalibrates pressure setpoints, and performs full system integration testing. We verify both seal chamber monitoring independently before return, critical in refineries and petrochemical plants where seal failure causes environmental spill.
How do you test Flowserve controllers before returning them to my plant in India?+
Synchronics uses a multi-level verification approach: component-level testing on oscilloscopes and multimeters, full functional testing on Flowserve test benches with actual sensor simulators, load simulation of pump or compressor duty cycles, and firmware integrity verification. For magnetic bearing controllers, we run extended stability tests verifying bias current linearity and rotor levitation. All repairs include 6-month warranty and full technical documentation.
What Flowserve fault codes or error messages indicate electronics failure versus mechanical pump damage?+
Flowserve electronics typically throw codes like 'MBC Amplifier Over-Temp', 'SSS Transducer Signal Loss', 'PLC Watchdog Timeout', or 'CMS Vibration Threshold Exceeded'. If your Flowserve pump displays electronics-related codes, Synchronics can diagnose the specific failed component (power supply, sensor card, communication module) remotely via phone and arrange pickup. Mechanical pump issues (cavitation, seal face wear) usually generate secondary codes once electronics have failed, so early electronic repair prevents cascading failures.
How do I send my FLOWSERVE 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 FLOWSERVE 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 FLOWSERVE 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 FLOWSERVE 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.
