GROVHAC INC Product Lines We Repair
Our engineers are trained on the full GROVHAC INC product range. Below are the major product families we service.
Rotary Vane Pump Controllers
Electronic controllers managing Grovhac rotary vane pump operation, speed regulation, and thermal protection. Common faults include relay failures, pressure sensor drift, and motor start winding burnout in high-ambient industrial facilities.
Screw Pump Drive Systems
Variable displacement screw pump drives with integrated VFD and load-sense electronics for energy-efficient vacuum generation. Repairs often involve capacitor failures, frequency converter issues, and solenoid valve malfunction.
Air-Oil Separator Electronics
Automated drain and separator control boards managing condensate removal and air quality filtration. Typical failures include float switch failures, solenoid sticking, and microprocessor reset loops.
Pressure Regulation Boards
Closed-loop pressure control and feedback modules for vacuum system setpoint management. Common issues include analog-to-digital converter errors, output relay welding, and signal conditioning circuit failures.
Temperature and Safety Modules
Integrated thermal monitoring and overpressure protection systems with audible alarm circuits. Repairs address thermistor sensor failures, relay chatter, and firmware corruption in smart units.

Common GROVHAC INC Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in GROVHAC INC equipment arriving at our workshop.
- ✓Rotary vane pump motor fails to start — Grovhac GV-series controller relay contacts oxidized from humidity or start winding capacitor dried out due to age and heat. Common in coastal Indian facilities with high salt air exposure.
- ✓Vacuum pump runs but pressure reading oscillates wildly — Pressure transducer signal wire corroded or floating due to loose crimp terminals on Grovhac GPR boards. Analog conditioning circuit noise filtering capacitors also fail in high EMI plants near welding or VFD equipment.
- ✓Electronic drain valve stuck open, oil leaks continuously — Solenoid plunger in Grovhac GOS series separator stuck due to varnish buildup or foreign debris from contaminated source oil. Microcontroller logic error also prevents proper on-off cycling.
- ✓Screw pump drive stops unexpectedly, alarm code ERR-12 displays — Load-sense solenoid in Grovhac GS drive loses pilot pressure due to blocked supply filter or fractured proportional spool. VFD frequency output also drops if DC bus capacitors are aged and swollen.
- ✓Temperature alarm triggers even when pump is cool — Thermistor thermal runaway or loose sensor probe in Grovhac GTS module allows false high-temperature signal. Analog comparator circuit in PCB fails due to solder joint crack around temperature reference IC.
- ✓Motor current drops to zero, output relay chatters — Grovhac controller output relay contacts wear after years of frequent start-stop cycling in batch manufacturing. Motor thermal overload contact also sticks if relay armature develops mechanical play due to spring fatigue.

Frequently Asked Questions — GROVHAC INC Repairs
Do you repair Grovhac Inc equipment anywhere in India?+
Yes. Synchronics Electronics repairs the full Grovhac Inc product range - vacuum pump controllers, screw drive systems, separator electronics, and pressure regulation boards. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Kolkata, Bangalore, and all major industrial cities. Full diagnostics and repairs completed in our Vadodara, Gujarat facility within 5-7 working days.
My Grovhac rotary vane pump shows ERR-05 relay fault code. What does this mean and can you fix it?+
ERR-05 on Grovhac GV controllers indicates motor starter relay failure or auxiliary relay contact wear. This is a common failure in Indian facilities with high ambient humidity and dust. Synchronics replaces the relay assembly with industrial-grade contacts, tests the restart logic, and confirms no secondary faults in the thermal sensing circuit. Most repairs completed same-day if relays in stock.
How often should I service Grovhac vacuum pump electronics in a hot climate?+
In Indian tropical and subtropical climates, preventive maintenance every 12 months is recommended for Grovhac controllers. Annual inspection includes capacitor aging check, relay contact cleaning, thermistor calibration verification, and pressure transducer signal validation. Synchronics offers annual preventive service contracts for industrial customers to avoid unexpected downtime during critical production runs.
Can Synchronics repair Grovhac electronics damaged by lightning strike or power surge?+
Yes. Grovhac controller boards often suffer surge damage to input rectifier stages and output relay drive transistors during monsoon lightning events common across India. Synchronics diagnoses surge damage using curve tracer and component-level testing, replaces damaged semiconductors and protection diodes, and upgrades surge suppression circuits where original design was inadequate. We recommend installing dedicated surge suppressors at plant main panel.
What is the typical turnaround time for Grovhac pump controller repair at Synchronics?+
Standard repair turnaround is 5-7 working days from receipt including full bench testing and recalibration against Grovhac specification sheets. Emergency same-day repair available for critical production equipment with expedited shipping charges. Loaner units available in some cases for high-availability facilities. Diagnostics report provided within 24 hours so you know expected cost before authorization.
How do I send my GROVHAC INC 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 GROVHAC INC 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 GROVHAC INC 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 GROVHAC INC 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.
