GRACO Product Lines We Repair
Our engineers are trained on the full GRACO product range. Below are the major product families we service.
Graco SureMix Proportioning Systems
Electronic proportioning and metering systems for two-component fluid mixing in polyurethane, epoxy, and adhesive applications. Common faults include proportioning drift, meter blockage errors, and electronic valve malfunction affecting product consistency.
Graco Lubrication Pump Drives
AC/DC motor drives and control electronics for centralized and progressive lubrication systems in machine tools, presses, and automotive assembly lines. Repair focus: motor overload faults, pressure sensor failures, and pump control relay degradation.
Graco Fluid Injection Control Electronics
Precision injection controllers for automotive and manufacturing workflows, managing nozzle firing sequences, pressure regulation, and fluid volume accuracy. Common failures include injection timing drift, pressure regulator electronics, and solenoid driver board burnout.
Graco Meter Pump Control Modules
Electronic modules governing metering pump speed, cycle timing, and output consistency in coating, adhesive, and sealant dispensing. Frequent faults: meter feedback circuit failure, pump speed sensor errors, and cycle timing drift.
Graco Two-Component Pump Systems
Integrated pump and electronics for automatic two-part material blending in manufacturing. Repair challenges include pump pressure balance, mixing ratio error, and solenoid valve stuck-open conditions.

All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common GRACO Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in GRACO equipment arriving at our workshop.
- ✓Proportioning ratio drift or inaccurate mix output — Meter feedback sensor contamination, proportioning valve spool stiction, or proportioner PCB analog-to-digital conversion error causing incorrect valve modulation and material blend ratio variance.
- ✓Lubrication pump fails to pressurize or loses pressure during cycle — Pump drive relay failure, pressure transducer open circuit, motor contactor sticking, or pump seal wear causing internal leakage past pump gear assembly.
- ✓Injection controller missing fire pulse or injector solenoid not energizing — Solenoid driver MOSFet burnout on injection control PCB, timing signal loss from microcontroller, or injector coil winding short-to-ground damaging driver stage.
- ✓Meter pump speed unstable or cycles at wrong frequency — Speed feedback sensor hall effect element contamination, pump speed control loop oscillation in firmware, or pump motor bearing wear causing speed ripple misread by electronics.
- ✓Two-component pump pressure imbalance or pump stall during mix — Pump pressure balancing valve stuck partially closed, pressure relief solenoid coil open, or pump drive electronics supplying unequal motor voltage to A/B pump motors.
- ✓Proportioning solenoid valve stuck open or closed, no fluid modulation — Solenoid driver IC failure or short circuit in proportioning valve solenoid coil winding, proportioning spool stuck due to resin buildup or corrosion in valve body.

Frequently Asked Questions — GRACO Repairs
Do you repair Graco equipment anywhere in India?+
Yes, absolutely. Synchronics Electronics repairs the complete Graco fluid handling and control electronics portfolio across India. We offer PAN India door pickup and delivery from Mumbai, Delhi, Pune, Bengaluru, Chennai, Hyderabad, Ahmedabad, Kolkata, and all major industrial cities. Your Graco pump drives, proportioners, injector controllers, and lubrication modules are serviced at our Vadodara, Gujarat facility with 2-3 week turnaround.
What Graco product lines does Synchronics repair?+
We repair Graco SureMix proportioners, lubrication pump drives, fluid injection controllers, meter pump modules, two-component pump systems, and all Graco pump motor drives. Whether your failure is a proportioning solenoid, pump speed sensor, injection timing board, or pressure transducer interface, our engineers diagnose and repair using Graco service manuals and OEM component replacement standards.
How quickly can Synchronics diagnose a Graco proportioner fault?+
Turnaround for Graco proportioner diagnosis is typically 24-48 hours. We bench-test proportioner PCBs, meter feedback sensors, and proportioning valve solenoids immediately upon intake. Most proportioner faults — drift, valve stiction, or sensor errors — are identified within one working day, and repair scheduling begins the same day.
Can you repair Graco pump drive electronics and motor controllers?+
Yes. Graco pump drive relay modules, motor contactor boards, 24V DC speed controllers, and three-phase induction motor drive electronics are core Synchronics repair services. We handle pressure switch integration, pump protection relay firmware resets, and motor soft-start circuit repair. Each pump drive is pressure-tested post-repair to confirm full pressurization during startup.
Does Synchronics provide firmware reprogramming for Graco injection or proportioning controllers?+
Yes. For Graco proportioners and pump injection controllers requiring firmware updates, parameter resets, or tuning adjustments, Synchronics has microcontroller reprogramming capability. We access Graco control modules, verify firmware version, flash corrected code if available, and validate all I/O and analog channels post-programming before return.
How do I send my GRACO 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 GRACO 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 GRACO 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 GRACO 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.
