GREATORK Product Lines We Repair
Our engineers are trained on the full GREATORK product range. Below are the major product families we service.
Greatork Hydraulic Power Units (HPU)
Complete self-contained hydraulic power stations with integrated pump, motor, reservoir, and cooling systems. Common issues include motor bearing wear, pump cavitation, filter blockage leading to pressure drops, and thermal runaway in sugar and textile plants.
Greatork Gear Pump Series
External gear pumps for high-pressure hydraulic circuits in steel rolling mills and mining equipment. Typical faults: internal leakage from wear, cavitation damage, shaft seal failure, and noise escalation indicating gear tooth damage.
Greatork Solenoid Valve Control Systems
24VDC and 230VAC proportional solenoid directional control valves with integrated electronics. Repair involves coil winding failures, spool stiction, pressure compensation issues, and controller circuit board faults.
Greatork Pressure Relief and Flow Control Valves
Pilot-operated and direct-acting pressure relief systems for load-sensing circuits. Common defects: spring relaxation, pilot stage blockage, spool wear causing creep, and calibration drift under thermal cycling.
Greatork Integrated Hydraulic Controllers (IHC)
PLC-based hydraulic system controllers with analog I/O, pressure transducer conditioning, and solenoid drive circuits for automated valve sequencing. Failures: PCB corrosion, relay contact wear, analog card crosstalk, firmware corruption.
Greatork Filtration and Temperature Management
Return-line and suction filters with clogging indicators, plus immersion heaters and thermostat assemblies for hydraulic fluid conditioning. Issues: bypass valve malfunction, sensor wire breakage, heating element burnout, and contamination ingress.

Common GREATORK Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in GREATORK equipment arriving at our workshop.
- ✓Greatork HPU motor runs but pump produces no flow — Internal gear pump cavitation due to blocked suction strainer, air ingress from loose inlet coupling, or mechanical seizure from contaminated hydraulic fluid. Sugar mill HPUs running 8000+ hours often develop this after missing scheduled filter changes.
- ✓Solenoid valve coil open circuit or intermittent energization — Moisture ingress into solenoid coil windings from humid plant environment, corrosion of terminal pins, or wire fatigue at strain relief. Greatork proportional valves (PROP-4/3, PROP-6/3) operate in 50-60% humidity across Indian textile and paper mills, accelerating insulation breakdown.
- ✓Greatork IHC controller shows erratic pressure readings or valve hunting — Analog input card channel crosstalk from loose shielded wiring, transducer connector corrosion, or firmware revision mismatch between controller and pressure card modules. Common in retrofitted systems mixing Greatork vintage equipment with newer sensor sets.
- ✓Pressure relief valve set point drifts over weeks or creeps under sustained load — Pilot stage internal leakage from spool wear, spring stress relaxation after extended thermal cycling, or debris (ferrous contamination) in pilot feedback gallery. Steel mill environments expose Greatork PRV units to temperature swings of 20-40°C daily.
- ✓Greatork proportional valve response time slow or spool stiction on directional change — Varnish buildup on spool from oxidized hydraulic fluid, microscopic contamination particles jamming spool lands, or solenoid pull force weakened by coil winding insulation degradation. Textile plant HPUs operating above 55°C continuously experience accelerated fluid oxidation.
- ✓Greatork HPU thermal runaway — fluid temperature rises uncontrollably despite cooler operation — Thermostat valve stuck open or closed preventing cooler activation, internal leakage across pump compensator generating excess heat, or cooler fan relay failed. Sugar mills with high ambient temperatures often operate HPUs near thermal limits.

Frequently Asked Questions — GREATORK Repairs
Do you repair Greatork equipment anywhere in India?+
Yes. Synchronics repairs the complete Greatork product range — hydraulic power units, gear pumps, solenoid directional valves, pressure relief systems, and integrated controllers. We offer PAN India door pickup service from Mumbai, Delhi, Bangalore, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Vadodara, Nagpur, and all other industrial cities. Your equipment is serviced at our fully equipped 8000 sq.ft. facility in Vadodara, Gujarat, with completion timelines of 3-7 days for routine repairs.
How long does Greatork HPU repair typically take, and what warranty do you provide?+
Standard Greatork hydraulic power unit repair takes 5-7 working days including motor inspection, pump teardown, component replacement, fluid flush, and full system pressure-flow testing. We provide 12 months warranty on all repaired Greatork assemblies against defective workmanship and component failure under normal operating conditions. Return shipping is handled via our logistics partner with documented tracking.
Can Synchronics repair Greatork solenoid proportional valves with embedded electronics?+
Yes — Synchronics is equipped to repair all Greatork PROP-4/3 and PROP-6/3 proportional directional control valves including spool reconditioning, solenoid coil rewinding, and integrated pressure compensation circuit board repair. We have access to Greatork coil winding specifications, spool dimensional drawings, and electronics schematics. Turnaround is 4-5 days for proportional valve full rebuild with post-repair functional validation.
What should I do if my Greatork HPU shows low flow but normal pressure?+
Low flow with normal pressure typically indicates internal pump leakage from wear or cavitation damage. First, check your suction strainer (blockage will cause this). If strainer is clean, have Synchronics perform a pump displacement test and internal inspection. Common causes are worn gear teeth, damaged shaft seals, or pilot-operated compensator malfunction. We recommend submitting a 100ml hydraulic fluid sample for particle count analysis — if fluid contamination exceeds ISO 4406 18/16/13 limits, your system needs flushing before reinstalling the repaired pump.
Does Synchronics stock Greatork spare parts and rebuild components?+
Synchronics maintains stock of critical Greatork spare components including solenoid coil assemblies, spool kits, seal packages, pressure relief springs, and thermal valve cartridges. For specialized items like complete HPU pump assemblies or motor-pump matched sets, we source directly from Greatork's authorized distributor network with typical lead time of 5-7 days. All our component sourcing ensures compatibility with original Greatork system specifications and warranty terms.
How do I send my GREATORK 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 GREATORK 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 GREATORK 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 GREATORK 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.
