CHEMTEX Product Lines We Repair
Our engineers are trained on the full CHEMTEX product range. Below are the major product families we service.
Chemtex Dosing Systems
Peristaltic and diaphragm metering pump controllers for chemical injection, coagulant dosing, and bleach feed. Common issues include controller calibration drift, pump power supply failures, and sensor signal loss affecting accuracy.
Chemtex Flow & Level Transmitters
Electromagnetic and capacitive sensors with 4-20mA and pulse output for water treatment, effluent monitoring, and process automation. Failures often involve zero/span drift, cable shielding issues, and analog output card malfunction.
Chemtex Analytical Controllers
pH, ORP, conductivity, and turbidity measurement and control systems for pharmaceutical batch processes and water quality monitoring. Common faults include electrode connector corrosion, input amplifier failures, and setpoint memory loss.
Chemtex Panel-Mount Indicators
Industrial grade LED and digital displays with relay output modules used in control panel integration. Repair needs include LED segment failure, relay contact sticking, and internal power supply burnout from field voltage transients.
Chemtex Integration & Communication Modules
Legacy and modern communication cards including RS-485, Modbus RTU, and analog interface boards. Issues include serial port failure, opto-isolator burnout, and firmware corruption in older legacy units still operating in Indian plants.

Common CHEMTEX Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in CHEMTEX equipment arriving at our workshop.
- ✓Dosing pump controller calibration loss and zero drift — Chemtex dosing systems experience capacitive memory drift in the analog calibration circuit after power cycling or exposure to electrical noise from motor starters on the same panel. The EEPROM calibration data can become corrupted during brownout conditions common in Indian industrial power distribution.
- ✓Flow transmitter zero offset and signal loss — Chemtex electromagnetic flow transmitters suffer from magnetized electrode fouling and cable grounding issues when installed near variable frequency drives without proper shielding. The 4-20mA output card often fails due to rust ingress in outdoor sensor installations across Indian water treatment plants.
- ✓pH controller electrode connector oxidation and input amplifier failure — Chemtex analytical controllers use spring-pin electrode connectors that corrode rapidly in humid pharma manufacturing environments and chemical plants. The input amplifier integrated circuit (Op-Amp IC) fails catastrophically when salt-laden moisture bridges the pin spacing, especially in coastal Indian facilities.
- ✓Panel indicator LED segment failure and display blanking — Chemtex DMI and DPI series indicators experience LED column driver IC burnout when exposed to power supply voltage transients from motor contactor switching. The internal 5V regulator fails without protection, causing cascading LED segment failures.
- ✓Modbus RTU communication card port failure and data corruption — Chemtex MOD-RTU interface cards lose serial communication when the RS-485 transceiver IC is damaged by lightning transients or incorrect cabling polarity. The firmware can become corrupted if power is lost during a write cycle, a common occurrence during Indian industrial power outages.
- ✓Peristaltic pump power supply module burnout and no-output condition — The internal buck converter in Chemtex CDX series pump controllers fails when exposed to unfiltered industrial mains power or when the pump load draws sustained inrush current during chemical injection cycles. Input rectifier diodes burn out without adequate input filtering.

Frequently Asked Questions — CHEMTEX Repairs
Do you repair Chemtex equipment anywhere in India?+
Yes. Synchronics Electronics repairs the full Chemtex product range including dosing systems, flow transmitters, analytical controllers, panel indicators, and communication modules. We operate pan-India pickup service from Mumbai, Delhi, Bangalore, Chennai, Hyderabad, Ahmedabad, Pune, Kolkata, and 50+ tier-2 cities. All repairs are performed in our Vadodara, Gujarat facility with 180+ engineers and same-day diagnostic turnaround.
How do you calibrate Chemtex dosing systems to meet pharma batch record accuracy?+
Synchronics calibrates Chemtex dosing pumps using certified NIST-traceable standard solutions at three setpoints (10%, 50%, 100% flow). We document calibration certificates with uncertainty statements and perform repeatability testing over 10 cycles. For pharmaceutical manufacturing, we verify ±2% accuracy compliance and provide calibration data suitable for FDA batch record attachment and Indian pharma audit requirements.
Can you repair legacy Chemtex instruments still running in older Indian plants?+
Yes. Synchronics has extensive experience servicing legacy Chemtex dosing controllers, analog pH meters, and early-generation Modbus communication cards still operating in Indian textile mills, water utilities, and chemical plants. We maintain stock of obsolete components, can reprogram older EPROMs, and provide drop-in replacements for discontinued models while preserving existing panel mounting and electrical connections.
What is the turnaround time for Chemtex flow transmitter repair?+
Standard Chemtex flow transmitter repair (electrode cleaning, cable replacement, output signal verification) requires 3-5 working days. Expedited repair with same-day diagnostics and overnight completion is available at premium rate. We ship repaired transmitters with field-test certificates and signal linearity charts back to your site with pan-India courier service.
Do you provide Chemtex spare parts and component replacements?+
Synchronics stocks common Chemtex replacement parts including electrode connector sets, 4-20mA output isolation cards, Op-Amp integrated circuits, RS-485 transceiver modules, and peristaltic pump tubing. We source original Chemtex components and authorized industrial-grade substitutes approved for pharmaceutical and process applications. All parts carry warranty and traceability documentation for compliance audits.
How do I send my CHEMTEX 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 CHEMTEX 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 CHEMTEX 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 CHEMTEX 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.
