DYNAMATIC Product Lines We Repair
Our engineers are trained on the full DYNAMATIC product range. Below are the major product families we service.
Variable Displacement Axial Piston Pumps (VDAP)
Dynamatic VDAP series delivers variable flow and pressure control for machine tools, injection moulding presses, and heavy earth-moving equipment. Common issues include swashplate wear, slipper pad erosion, and control valve stiction causing loss of displacement adjustment and pressure regulation.
Fixed Displacement Gear Pumps (FDG)
Compact, robust Dynamatic FDG pumps used in agricultural tractors, construction equipment, and hydraulic power units. Typical failures include internal leakage from gear wear, bearing degradation, and inlet cavitation damage from contaminated fluid.
Proportional Spool Valves (PSV)
Dynamatic PSV proportional valves control directional flow and pressure in automated machine tools, press systems, and CNC equipment. Common faults include solenoid coil burnout, spool stiction from contamination, and pilot pressure loss affecting flow response.
Axial Piston Motors (APM)
High-speed Dynamatic APM motors provide precise torque control in spindle drives, feed mechanisms, and rotary actuators. Repair needs include swashplate bearing wear, internal leakage from port plate erosion, and loss of speed regulation.
Integrated Hydraulic Control Units (IHCU)
Complete Dynamatic IHCU assemblies combine pump, motor, valves, and pressure relief in one manifold for machine automation. Failures involve proportional valve malfunction, internal bypass leakage, and pilot circuit loss due to component fatigue.
Servo Valve Systems (SVS)
Dynamatic SVS precision servo valves deliver micro-level flow and pressure control for aerospace, precision metalworking, and motion control applications. Common issues include armature stiction, nozzle flapper wear, and feedback transducer drift.

Common DYNAMATIC Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DYNAMATIC equipment arriving at our workshop.
- ✓Pump swashplate bearing wear and scoring — Extended operation with inadequate hydraulic fluid filtration or temperature control in Dynamatic variable displacement pumps causes abrasive particle embedding and spalling of the swashplate bearing race. This reduces displacement control accuracy and increases internal leakage.
- ✓Proportional valve solenoid coil failure and burnout — Dynamatic proportional spool valves experience solenoid coil burnout from sustained high current draw, moisture ingress into the armature housing, or impact damage during installation. Failed coils prevent proportional current modulation and valve responsiveness.
- ✓Slipper pad erosion and leakage in variable pumps — Dynamatic VDAP pump slipper pads erode under cavitation conditions, lack of pump outlet pressure compensation, or operation with contaminated hydraulic fluid containing abrasive particles. Eroded pads lose sealing efficiency and increase case drain flow.
- ✓Port plate internal leakage and pressure drop — Dynamatic pump and motor port plates develop internal leakage from erosion of the kidney-shaped inlet and outlet ports, seal face wear, and loss of pressure-balancing surface geometry. This causes loss of system pressure and reduced equipment output torque.
- ✓Spool stiction and directional valve lock-up — Dynamatic proportional and directional spool valves develop stiction from varnish deposits, rust particles, and contamination buildup on the spool lands and bores. This prevents smooth spool movement and causes lag or complete loss of flow response.
- ✓Feedback transducer drift and signal loss in servo valves — Dynamatic servo valve feedback transducers (LVDT or pressure sensors) experience signal drift from thermal cycling, connector corrosion, and internal electronics degradation. This causes valve instability, hunting, or loss of proportional control authority.

Frequently Asked Questions — DYNAMATIC Repairs
Do you repair Dynamatic equipment anywhere in India?+
Yes. Synchronics repairs the complete Dynamatic hydraulic pump, motor, valve, and control system portfolio across all of India. We offer PAN-India door pickup from all major industrial hubs — Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Bangalore, and smaller cities. All repairs are performed in our fully equipped Vadodara facility, with overnight turnaround available for priority jobs.
What is the typical repair cost and turnaround time for a Dynamatic variable displacement pump?+
Dynamatic variable displacement pump repair costs range from INR 15,000 to INR 45,000 depending on wear severity and component replacement needs. Standard turnaround is 5-7 working days from receipt; express service is available in 2-3 days for additional charges. We provide a detailed inspection report and cost estimate before proceeding, with a 12-month repair warranty.
Can Synchronics recalibrate Dynamatic proportional valve response and pressure settings to my machine requirements?+
Yes. Synchronics has proprietary Dynamatic valve test benches that allow us to recalibrate proportional spool valve response curves, pilot pressure settings, and load compensation to match your specific machine tool or equipment operating parameters. We document all settings in a calibration certificate and test the valve under simulated load conditions before dispatch.
Do you carry Dynamatic spare parts stock or can you source OEM components quickly?+
Synchronics maintains a stock of commonly replaced Dynamatic spare parts including slipper shoes, port plate seals, solenoid coils, and transducers. For specialty items, we have direct relationships with Dynamatic authorized distributors across India and can source components within 2-3 working days, ensuring your repair is not delayed by parts availability.
What happens if my Dynamatic pump fails again after repair?+
All Dynamatic repairs from Synchronics carry a 12-month comprehensive warranty covering defects in workmanship and material. If the same fault recurs, we repair or replace the unit free of charge, including return shipping. We also provide detailed operating guidelines and maintenance recommendations to prevent premature repeat failure.
How do I send my DYNAMATIC 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 DYNAMATIC 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 DYNAMATIC 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 DYNAMATIC 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.
