GRAHAM Product Lines We Repair
Our engineers are trained on the full GRAHAM product range. Below are the major product families we service.
Graham Ejectors
Single and multi-stage steam ejectors for vacuum generation in condenser systems. Common issues include nozzle erosion, diffuser fouling, motive steam loss, and performance degradation under varying load conditions.
Surface Condensers
Heat exchange condensers for power plants and industrial cooling. Typical faults include tube fouling, scaling, tube-side corrosion, and shell-side bypass around tube bundles affecting condenser effectiveness.
Vacuum System Packages
Integrated vacuum generation and maintenance systems combining ejectors, intercoolers, and after-coolers. Issues include pressure drops, temperature control failures, and inter-stage separator malfunctions.
Intercoolers and After-Coolers
Cooling equipment between ejector stages. Repairs address tube leaks, fouling deposits, thermal bypass, gasket failures, and loss of cooling effectiveness in multi-stage ejector trains.
Control and Instrumentation
Vacuum regulation, pressure monitoring, and automatic ejector flow control modules. Common faults include pressure transmitter calibration drift, control valve stiction, flow control malfunction, and sensor failures.

Common GRAHAM Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in GRAHAM equipment arriving at our workshop.
- ✓Ejector nozzle and diffuser erosion — High-velocity steam impingement and suction vapour friction cause progressive nozzle throat wear and diffuser surface erosion, reducing motive power and suction capacity over thousands of operating hours in thermal power plants.
- ✓Condenser tube fouling and scaling — Cooling water deposits, biological growth, and corrosion products accumulate inside condenser tubes, reducing heat transfer and raising exhaust temperature. Indian refineries using untreated cooling water experience accelerated fouling in hot climates.
- ✓Intercooler bypass and leakage — Gasket degradation, tube-side corrosion perforation, and shell cracks allow uncooled steam to bypass the cooling section. This raises inter-stage temperature, reduces overall ejector compression ratio, and degrades system vacuum capability.
- ✓Vacuum pressure regulator drift and control instability — Pressure transmitter sensor fouling, pilot valve stiction, and dead-leg process connections cause erratic vacuum readings and uncontrolled ejector flow modulation, destabilizing condenser performance.
- ✓After-cooler thermal effectiveness loss — Cooling water fouling, fin blockage in air-cooled designs, and partial vapour condensation inside the cooler prevent adequate temperature reduction between ejector stages, raising discharge temperature and reducing system compression.
- ✓Suction line pressure drops and performance degradation — Erosion of suction piping, accumulation of condensed liquids in low points, and filter element blockage reduce available suction pressure, causing the ejector system to operate outside its designed envelope and fail to maintain target vacuum level.

Frequently Asked Questions — GRAHAM Repairs
Do you repair Graham equipment anywhere in India?+
Yes. Synchronics repairs the complete Graham product range including ejectors, surface condensers, vacuum systems, and control modules across India. We offer PAN India door pickup service from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, and all other cities. All repairs are performed at our Vadodara, Gujarat facility with 180+ experienced engineers and 30 years of industrial electronics repair expertise.
Can you repair Graham ejectors without replacing the internal nozzles and diffusers?+
Often yes. Synchronics performs detailed erosion mapping and micro-measurement of nozzle throat geometry and diffuser profiles. For minor wear, we perform precision machining to restore original dimensions and maintain designed flow characteristics. However, if erosion exceeds material thickness tolerances or perforation risk exists, we recommend replacement internals from authentic Graham or equivalent sources. All repairs include flow testing and capacity verification.
What is the typical turnaround time for Graham condenser repair?+
Standard Graham surface condenser repairs take 10-15 working days depending on fouling severity and tube perforation extent. Urgent repairs can be expedited to 5-7 days with priority scheduling. Intercooler and after-cooler repairs typically complete in 7-10 days. We provide daily progress updates and can arrange temporary loaner equipment for critical applications to minimize production downtime at your facility.
How do you prevent Graham ejector performance degradation in Indian power plants?+
Synchronics recommends preventive maintenance including annual nozzle inspection, suction and discharge piping acoustic testing, and pressure transmitter recalibration. We document baseline performance curves and trend analysis to detect early erosion. For plants using untreated cooling water, we advise chemical water treatment upgrades and regular filter element changes. Our maintenance programme extends ejector service life by 40-60 percent and maintains vacuum performance within OEM design margins.
Do you stock genuine Graham parts and replacement assemblies?+
Synchronics maintains relationships with multiple Graham authorized distributors and OEM part suppliers in India. We source genuine ejector internals, condenser tube bundles, gasket kits, and control modules on demand. For obsolete or long-lead Graham parts, we source equivalent materials from qualified alternative suppliers vetted for dimensional and material compatibility. All replacement components are tested before installation to guarantee fit and performance in your Graham system.
How do I send my GRAHAM 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 GRAHAM 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 GRAHAM 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 GRAHAM 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.
