MURPHY Equipment We Repair — By Category
MURPHY Product Lines We Repair
Our engineers are trained on the full MURPHY product range. Below are the major product families we service.
Murphy Pressure Switches (Mechanical & Electronic)
Range of adjustable and fixed-setting pressure switches for pump protection, compressor unloading, and system monitoring. Common issues include setpoint drift, electrical contact wear, and bellows fatigue in high-vibration environments.
Murphy Differential Pressure Switches
Precision DP switches for filter clogging detection, level measurement, and flow verification. Faults typically involve diaphragm rupture, snapping action failure, and calibration loss under thermal cycling.
Murphy Flow Meters & Paddle Switches
Turbine and paddle-wheel flow sensors for hydraulic, cooling water, and lube oil circuits. Repair challenges include rotor bearing wear, signal loss from water ingress, and reed switch malfunction.
Murphy Level Switches (Float & Capacitive)
Float-operated and capacitive level switches for tank monitoring and pump start/stop control. Common failures are float arm corrosion, electrical contact pitting, and dielectric breakdown in wet environments.
Murphy Solenoid Valves & Pilot Controls
Direct and pilot-operated solenoid valves with integrated safety functions for industrial control. Typical issues include coil burnout, plunger stiction, and armature seal leakage.
Murphy Temperature Switches & Thermostats
Bimetallic and resistance-based temperature switches for thermal protection and heating control. Faults include calibration shift, contact oxidation, and stem connection looseness.
Why Choose Synchronics for MURPHY Repairs?
PCB-Level Expertise
We repair down to the component level — not just swap boards. Our engineers identify root causes, replace failed IGBTs, capacitors, processors, and gate drivers on MURPHY equipment.
Fast Turnaround
Standard 7–10 working days. Express 3–5 days available for critical breakdowns. Emergency same-day/next-day service for unplanned downtime.
6-Month Warranty
Every repaired unit ships with a 6-month comprehensive warranty on parts and labour. Our repair success rate is over 94% across all brands.
All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common MURPHY Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in MURPHY equipment arriving at our workshop.
- ✓Pressure switch setpoint drift and recalibration loss — Continuous vibration in compressor and pump installations causes internal spring pre-load to shift, resulting in false pressure readings. Temperature cycling and mechanical shock accelerate this in Indian industrial plants running 24/7.
- ✓Electrical contact wear and intermittent switching failures — Silver-nickel contacts in Murphy switches oxidise and wear under high inrush current loads typical in India's grid-connected machinery. Arcing damage accumulates over 5-10 years of operation.
- ✓Bellows and diaphragm rupture causing fluid leakage — Over-pressurisation beyond equipment rating or corrosion from moisture ingress causes bellows to fail. Murphy switches exposed to salt-laden air in coastal refineries near Vadodara and Mumbai experience accelerated fatigue.
- ✓Float arm corrosion and mechanical binding in level switches — Continuous immersion in mineral-laden water, chemical tanks, or humid air causes stainless steel float arms to pit and corrode. Binding prevents smooth pivoting and causes false level indication.
- ✓Solenoid coil burnout and no-energisation fault — Sustained voltage spikes from motor soft-starters and VFDs damage Murphy solenoid insulation. Poor earthing and missing surge protection are common in Indian industrial control panels.
- ✓Reed switch and magnetic pickup signal loss — Water ingress into sealed switch cavities shorts out reed switch circuits. Magnetic scale loss on internal magnets reduces switching sensitivity in flow meters used in cooling systems.

Frequently Asked Questions — MURPHY Repairs
Do you repair Murphy equipment anywhere in India?+
Yes. Synchronics repairs the full Murphy product range — pressure switches, flow meters, level sensors, solenoid valves, and temperature controls. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, and all other cities. Same central facility in Vadodara, Gujarat ensures fast turnaround and quality control.
Can you recalibrate and certify Murphy pressure switches to international standards?+
Yes. We calibrate Murphy switches on ISO/IEC 17025 accredited pressure benches with NIST-traceable standards. All switches are tested at 0%, 50%, and 100% of range with setpoint verification and hysteresis measurement. We issue calibration certificates valid for 12 months compliance with ASME, API, and Indian boiler regulations.
What is the typical turnaround time for Murphy switch repair at Synchronics?+
Standard turnaround is 5-7 working days for most Murphy switches including calibration and testing. Express 48-hour service available for critical safety applications in power plants, refineries, and water treatment facilities. We maintain stock of OEM spare parts and replacement contact assemblies to minimise downtime.
Do you repair Murphy solenoid valves and pilot-operated control assemblies?+
Yes. We fully service Murphy solenoid valves including plunger inspection, coil rewind, seal replacement, and pilot circuit troubleshooting. We test at system pressure and verify response time. For integrated safety systems, we provide functional test reports and recommend maintenance intervals based on operating hours.
Are Murphy switches used in Indian refineries and power plants easy to replace or repair in-house?+
Murphy switches are field-repairable but require certified test equipment and trained technicians for accurate recalibration. Synchronics provides on-site emergency repair support at Reliance, IOCL, NTPC, and regional facilities. We also offer planned preventive maintenance contracts to avoid unexpected failures in critical control loops. Most plants prefer outsourcing to us rather than maintaining in-house calibration capability.
How do I send my MURPHY 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 MURPHY 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 MURPHY 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 MURPHY 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.
