LUHO Equipment We Repair — By Category
LUHO Product Lines We Repair
Our engineers are trained on the full LUHO product range. Below are the major product families we service.
LUHO Electro-Pneumatic Lubricators (EPL Series)
Solenoid-driven lubricators for automatic oil delivery in machine tool spindles, hydraulic systems, and industrial conveyors. Common faults include solenoid coil burnout, sticky valve spools, and air-line pressure irregularities causing over/under-lubrication and bearing wear.
LUHO Progressive Distributor Blocks (PDB Series)
Multi-outlet progressive metering units for sequential lubrication of spindle bearings, tool changers, and linear guide rails. Failures include internal gear wear, oil starvation in outlet ports, and pressure-relief valve sticking due to contamination.
LUHO Digital Oil Level Monitoring (DOM Series)
Capacitive or float-switch sensors for real-time lubrication tank level and contamination detection. Repair issues involve sensor fouling, cable insulation failure, relay malfunction, and calibration drift in dosing feedback loops.
LUHO Central Lubrication Pump Units (CLU Series)
Electric-driven gear or screw pumps feeding pressurised oil to machine tool spindles and multi-station production lines. Common problems: pump cavitation from blocked suction lines, motor bearing seizure, pressure relief valve leakage, and oil oxidation in hot spindle applications.
LUHO Metering Valve Cartridges (MVC Series)
Integrated flow-control and check-valve cartridges for high-precision spindle and bearing lubrication. Faults include internal spool stiction, wear rings degradation, and pilot pressure loss affecting metering accuracy and oil film thickness.
LUHO PLC-Based Lubrication Controllers (ELC Series)
Programmable logic modules for automated lubrication scheduling, machine cycle integration, and alarm management. Repair scope covers software corruption, I/O module failures, communication port issues (RS232/Ethernet), and battery-backed RTC (real-time clock) failure.

Common LUHO Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in LUHO equipment arriving at our workshop.
- ✓LUHO solenoid coil burnout in EPL lubricators — Continuous 24 VDC supply without duty-cycle control, moisture ingress through connector, or overvoltage spikes from unshielded pneumatic lines cause insulation breakdown and open-circuit coil resistance. Indian humidity and monsoon-season moisture exacerbate this issue.
- ✓Progressive distributor block outlet starvation — Viscous oil thickening in winter or high-temperature oxidation in spindle-mounted units restricts internal gear rotation. Contamination particles jam the porting galleries, blocking downstream lubrication to critical bearing sets.
- ✓LUHO DOM capacitive sensor false alarm or no signal — Dielectric coating buildup on sensor probe electrodes, cable shielding corrosion near tank termination, or capacitance drift due to fluid property changes (viscosity, additives) cause erratic level detection. High-humidity coastal and food-processing plants are susceptible.
- ✓CLU central pump cavitation and loss of pressure — Blocked suction strainer, kinked inlet hose, or low oil level in feed tank starves the pump inlet, creating vapour pockets that collapse violently and damage impeller blades. Extended dry-run operation is common during maintenance downtime in Indian plants.
- ✓LUHO metering valve cartridge spool stiction — Oil oxidation deposits, metallic wear debris, and varnish formation accumulate on control spools, causing erratic or zero flow despite correct pilot pressure. High spindle speeds and elevated operating temperatures (>60 degC) in tool changers accelerate degradation.
- ✓LUHO ELC controller program loss or RTC battery failure — Mains supply interruption during write cycle corrupts firmware on non-volatile memory. Coin-cell RTC batteries (CR2032) typically expire after 5-7 years, causing timestamp loss and lubrication cycle mis-triggering in automated plants.

Frequently Asked Questions — LUHO Repairs
Does Synchronics repair LUHO lubricators across India?+
Yes. Synchronics repairs all LUHO product lines — electro-pneumatic lubricators, progressive distributors, digital sensors, central pump units, metering cartridges, and PLC controllers. We offer PAN-India pickup and logistics from Chennai, Hyderabad, Bengaluru, Mumbai, Pune, Delhi, Ahmedabad, and all tier-1 and tier-2 industrial cities. Our 180+ engineers at the Vadodara facility handle diagnostics, board-level repair, solenoid rewinding, sensor recalibration, and full functional testing under LUHO specifications.
What is the typical turnaround time for LUHO lubricator repair?+
Routine repairs (solenoid replacement, valve cleaning, sensor recalibration) take 3-5 working days. Complex issues (progressive block internal gear replacement, pump cavitation damage, ELC firmware recovery) require 7-10 days. Synchronics offers express 24-48 hour service for critical production-line failures. We provide loaner units during repair and same-day delivery in Vadodara, Gujarat.
Can Synchronics repair LUHO equipment under warranty?+
Yes. Synchronics is an authorised independent repair partner for LUHO industrial electronics in India. We repair in-warranty and out-of-warranty units without voiding remaining manufacturer coverage. We preserve all LUHO firmware, calibration data, and serial number integrity. Original LUHO parts are used where critical; equivalent industrial-grade alternatives (seals, O-rings, cables) are supplied with full traceability documentation.
What is LUHO EPL solenoid burnout and how do you prevent it?+
LUHO EPL electro-pneumatic lubricators use 24 VDC solenoids to trigger oil metering valves. Burnout occurs when continuous DC supply (without pulsed duty cycling), moisture ingress, or mains voltage spikes exceed solenoid coil insulation rating. Synchronics diagnoses burnout via insulation-resistance (megohm) testing and coil inductance measurement. Prevention: install 24 VDC surge suppressors (varistors or RC networks) across solenoid terminals, provide cabinet-mounted isolator relays, and ensure dry connector sealing. We retrofit protection modules to prevent recurrence.
How do I know if my LUHO progressive distributor block is failing?+
Signs of LUHO PDB failure: uneven lubrication across spindle bearings (visible wear patterns), audible grinding noise at spindle start-up, loss of downstream outlet flow on pump gauge, oil leakage from outlet ports, or slow/no response to pump cycle activation. Synchronics uses precision flow benches to measure outlet rates (cc/min per LUHO spec), ultrasonic inspection to detect internal gear wear, and pressure transducers to confirm sequence timing. We report root cause and advise block reconditioning versus replacement based on wear severity and component availability in India.
How do I send my LUHO 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 LUHO 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 LUHO 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 LUHO 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.
