ADOLF MOHR Product Lines We Repair
Our engineers are trained on the full ADOLF MOHR product range. Below are the major product families we service.
Adolf Mohr Proportional Directional Valves
Electrohydraulic spool valves with integrated electronics for flow control and directional switching. Common issues include solenoid coil failures, spool stiction from fluid contamination, and electronic control module drift causing erratic pressure or flow response.
Adolf Mohr Hydraulic Pumps and Motors
Axial and radial piston pumps used in industrial machinery drives. Repair focus includes internal leakage, worn swashplate mechanisms, pressure relief valve sticking, and control spool wear affecting displacement accuracy.
Adolf Mohr Pressure Compensator Electronics
Load-sensing compensator modules with analog and proportional control inputs. Typical faults include potentiometer nonlinearity, amplifier board component degradation, and pressure transducer drift affecting system stability.
Adolf Mohr Flow Control Valves
Precision flow dividers and combiner valves for multi-actuator synchronization. Common problems involve spool centering spring failure, hydraulic fluid viscosity-related stiction, and throttle metering edge wear.
Adolf Mohr Solenoid and Pilot Valve Assemblies
Pilot-operated directional control solenoids and check valves. Repair addresses coil insulation breakdown, pilot stage internal leakage, spring corrosion from water ingress, and electromagnetic coil overheating.

Common ADOLF MOHR Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ADOLF MOHR equipment arriving at our workshop.
- ✓Solenoid coil insulation failure causing erratic valve response — Adolf Mohr proportional valves operate in high-vibration textile and packaging machinery environments. Coil windings experience electrical degradation from moisture ingress, thermal cycling, and vibration-induced fracturing of enamel insulation layers.
- ✓Spool stiction and slow actuator response in proportional valves — Hydraulic fluid contamination (ISO cleanliness > 20/18/15) causes sludge buildup on Adolf Mohr spool lands, blocking pilot pressure galleries and creating friction that opposes electronic command signals.
- ✓Pressure compensator drifts causing excessive system pressure or oscillation — Adolf Mohr pressure compensator electronics drift due to potentiometer wear, amplifier capacitor aging, and pressure transducer signal nonlinearity. Load-sensing systems lose accuracy over 8-10 years of continuous operation in paper mills and textile dyeing plants.
- ✓Hydraulic pump internal leakage and reduced displacement — Adolf Mohr axial piston pumps suffer swashplate bearing wear, slipper pad erosion, and barrel port plate scoring when fluid contamination exceeds 21/19/16 ISO cleanliness or when operating beyond rated case pressure limits.
- ✓Flow control valve erratic output and synchronization failure — Adolf Mohr flow divider spool centering springs fatigue and break after 5-7 years in high-cycle textile machinery, or internal spools wear due to abrasive particle contamination, causing metering edge damage and flow imbalance.
- ✓Pilot valve internal leakage and pressure instability — Adolf Mohr pilot-operated check and solenoid valves develop internal leakage when seal elements (elastomer o-rings, poppet seals) degrade from temperature cycling, fluid oxidation, or microbial growth in tanks with high moisture.

Frequently Asked Questions — ADOLF MOHR Repairs
Do you repair Adolf Mohr equipment anywhere in India?+
Yes. Synchronics repairs the complete Adolf Mohr product portfolio including proportional directional valves, hydraulic pumps, flow control modules, and pressure compensators. We offer PAN-India pickup and delivery from major cities - Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Kolkata, and all tier-2 industrial centers. All repairs are completed in our Vadodara, Gujarat facility with turnaround typically 5-7 working days.
What is your experience with Adolf Mohr proportional valve solenoid failures?+
Synchronics has repaired over 800+ Adolf Mohr proportional valve solenoid assemblies since 1994. We specialize in insulation testing, coil rewind, and complete solenoid replacement for LPDS-4 through LPDS-10 series. Our solenoid shop is equipped with megohmeter testing (5kV), thermal imaging, and coil resistance verification. We maintain a stock of OEM-compatible solenoid cartridges and custom-wind coils to specification.
Can you repair Adolf Mohr hydraulic pumps without factory rebuild?+
Absolutely. Synchronics performs complete in-house overhaul of Adolf Mohr axial and radial piston pumps (AP and RP series). We disassemble, inspect all internal components under magnification, replace worn spools, slippers, swashplate bearings, and port plates, then reassemble and test to OEM displacement and pressure specifications. Full case flushing and fluid analysis is included. Cost is typically 40-50% less than factory rebuild.
How do you test Adolf Mohr proportional valves after repair?+
Synchronics uses a dedicated Adolf Mohr valve test bench with pressure (0-350 bar), flow (0-500 L/min), and solenoid command signal capability. We verify proportional response linearity, spool free-travel, pressure drop, and internal leakage under load steps. All test data is documented and provided to customers. Critical textile and paper industry applications receive bench certification before shipment.
What hydraulic fluid does Synchronics use for Adolf Mohr system flushing?+
We use ISO VG 32 mineral oil flushing fluid meeting ISO 11158 specification (cleanliness 15/13/10 or better) for all Adolf Mohr system flushes. Flushing is performed at 40-50 L/min through 3-micron return filters until fluid cleanliness reaches 18/16/13 ISO code. We then fill systems with customer-specified operating fluid (typically ISO VG 46 HLP or HETG) and run full commissioning cycle before delivery.
How do I send my ADOLF MOHR 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 ADOLF MOHR 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 ADOLF MOHR 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 ADOLF MOHR 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.
