PSG Equipment We Repair — By Category
PSG Product Lines We Repair
Our engineers are trained on the full PSG product range. Below are the major product families we service.
PSG Haldex Gear Pumps
External and internal gear pump designs for high-pressure hydraulic systems. Common repairs include bearing wear, gear tooth scoring, pressure valve failures, and seal degradation leading to internal leakage and pressure loss.
PSG Progressive Cavity Pumps
Single-screw positive displacement pumps for viscous fluids including crude oil, molasses, and polymer solutions. Typical failures involve rotor-stator wear, elastomer degradation, suction cavitation, and internal bypass leakage reducing volumetric efficiency.
PSG Rotary Vane Motors
Fixed and variable displacement vane motors for actuation and auxiliary drive applications. Common faults include vane blade chipping, porting wear, bearing seizure, and seal leakage from fluid contamination and thermal cycling.
PSG Rotary Screw Pumps
Twin-screw designs for high-capacity fluid transfer and energy-dense hydraulic circuits. Repairs address screw lobe wear patterns, shaft seal failures, differential pressure imbalances, and cavitation-induced erosion in pump inlets.

All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common PSG Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in PSG equipment arriving at our workshop.
- ✓PSG Haldex gear pump pressure drop — Internal gear tooth wear and crescent-shaped relief paths degrade hydraulic sealing, allowing oil bypass. Sugar mill and paper industry applications with contaminated fluids accelerate this degradation.
- ✓Progressive cavity pump rotor-stator slippage — Elastomer stator wear from abrasive particle ingestion or thermal cycling reduces eccentric fit tolerance, causing volumetric loss and reduced flow output to downstream equipment.
- ✓PSG vane motor blade fracture and seizure — Contaminated hydraulic oil introduces hard particles that score porting plates and vane slots. Repeated impact loads during cold-start operations trigger blade fatigue cracking and jamming.
- ✓Rotary screw pump cavitation and noise — Inlet restriction from clogged suction filters or air ingress into pump inlet causes vapor bubble formation, leading to erosion on screw lobe surfaces and increased vibration in mill drive systems.
- ✓PSG pump seal failure and oil leakage — Elastomer seals degrade from thermal stress (oil temperature >65°C), hydraulic shear in high-speed applications, and incompatibility with synthetic hydraulic fluids used in modern Indian refineries.
- ✓Haldex pump displacement loss under load — Worn pressure relief valve spool sticks in partially open position, allowing uncontrolled oil bypass and loss of system pressure. Common in dusty sugar mill and cement plant environments.

Frequently Asked Questions — PSG Repairs
Do you repair PSG pumps and motors anywhere in India?+
Yes. Synchronics is India's largest dedicated repair facility for PSG Haldex, PSG progressive cavity, and PSG vane motor equipment. We offer PAN-India free pickup and delivery from all major industrial hubs including Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Indore, and Vadodara. All repairs are completed in our 35,000 sq.ft. Vadodara facility with 180+ specialized technicians and are backed by a 24-month warranty.
What is the typical repair turnaround time for a PSG Haldex gear pump?+
Standard PSG Haldex pump repairs take 7-10 working days from intake to dispatch, including full diagnostics, component replacement, precision machining, testing, and documentation. Emergency expedited repairs for critical production downtime can be completed in 48-72 hours. Our team maintains OEM parts inventory for the PSG Haldex series to minimize lead time.
How do you diagnose wear in PSG progressive cavity pumps before full disassembly?+
Synchronics uses non-destructive testing including pressure curve analysis, volumetric flow testing at rated speed, thermal imaging of stator walls, and endoscopic inspection of rotor surfaces. This helps us assess whether partial component replacement (stator only) or full overhaul is needed, reducing repair costs and downtime for Indian sugar mills and oil refineries.
Can you repair PSG pumps that have been running on synthetic hydraulic fluids?+
Yes. Synchronics specialists understand elastomer compatibility across mineral oils, biodegradable esters, and synthetic PAO fluids used in modern Indian manufacturing plants. During repair, we replace seals with materials matched to your specific hydraulic fluid specification and test the restored pump with your actual working fluid to ensure compatibility and long service life.
Do you provide technical support for optimizing PSG pump selection and maintenance in Indian plants?+
Yes. Beyond repairs, Synchronics offers on-site condition monitoring, predictive maintenance training for operators, and recommendations for filtration and fluid management to extend PSG equipment life. We work with sugar mills, cement plants, and chemical manufacturers across India to reduce unplanned downtime and repair frequency through better maintenance practices.
How do I send my PSG 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 PSG 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 PSG 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 PSG 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.
