Repair & Refurbishment Services
When key components fail, GWT’s repair & refurbishment services restore your water treatment Dubai systems to like-new condition. We handle pumps, membranes, skid modules, and control panels under one roof. Our fast, OEM-quality process extends asset life and protects your industrial water purification investment.
Mechanical Overhaul Services
We rebuild your core mechanical equipment to factory standards, minimizing downtime and restoring full capacity.
Pump Rebuilds to Restore Flow & Pressure
We strip high-pressure and dosing pumps to inspect impellers, bearings, seals, and shafts. We replace worn parts with genuine OEM components and reassemble to factory tolerances. Every rebuild includes performance testing on our test bench to verify original flow rates and pressure. You avoid lengthy downtime and costly rentals.
- Bearing and seal replacements to prevent leaks under full load
- Impeller balancing for smooth operation
- Pressure testing at operating conditions
- Rapid turnaround from local workshops
Schedule a mechanical overhaul now to keep your pumps running at peak efficiency.
Valve & Actuator Servicing for Leak-Free Operation
Valves regulate flow throughout your plant. Our technicians service ball, butterfly, diaphragm, and check valves to ensure tight shutoff. We replace diaphragms, seats, packing, and gaskets, then calibrate electric or pneumatic actuators for precise control. This work stops leaks, improves process stability, and reduces chemical losses.
- Diaphragm and seat replacements for reliable sealing
- Actuator calibration for accurate opening/closing
- Gland packing adjustments to eliminate drips
- Function tests under full pressure
Book valve and actuator servicing today to eliminate leaks and maintain precise flow control.
Membrane & Filter Restoration
Our membrane and filter restoration services revive element performance and extend system run times.
Customized CIP Cycles for Membrane Cleaning
Membrane fouling cuts capacity and raises energy use. We design and run clean-in-place (CIP) cycles tailored to your RO, UF, and NF elements. Our chemical recipes and flow patterns remove scale, biofilm, and organic fouling. Post-CIP testing confirms salt rejection above 99.5% and flux rates within 5% of new membranes.
- Automated CIP skid for safe handling of chemicals
- Flow reversal and soak cycles for deep cleaning
- One-hour CIP turnaround to minimize downtime
- On-site tuning of parameters for optimal results
Refresh your membranes with our CIP service to regain full capacity and reduce energy consumption.
Element Replacement & Vessel Integrity Checks
When elements reach end-of-life, we swap them out with genuine OEM cartridges. We inspect pressure vessels for corrosion, perform hydrostatic tests, and apply linings as needed. These checks prevent leaks and restore safety margins. Upgrading to next-generation elements can boost recovery by up to 10%.
- OEM membrane cartridges eliminate compatibility issues
- Hydrostatic testing at rated pressure
- Vessel relining to extend service life
- Detailed integrity reports for compliance
Replace aged elements and verify vessel integrity today to sustain water quality and safety.
Control System Upgrades
Modern controls boost reliability, data access, and remote management capabilities.
PLC/SCADA Retrofits for Remote Monitoring
Obsolete PLCs and SCADA systems limit visibility. We retrofit modern controllers and migrate to secure SCADA platforms. You get real-time remote access, historical data logging, and trend analysis. Automated alarms notify GWT’s support center within minutes, reducing incident response time to under an hour.
- Touchscreen HMIs for intuitive operator interaction
- VPN-secure remote diagnostics from any device
- Historical data storage for performance reviews
- Alarm management with SMS/email notifications
Upgrade your PLC/SCADA now to improve monitoring and cut response times.
Control Panel Rebuilds & Software Enhancements
Our panel rebuilds replace worn relays, breakers, and wiring. We install new HMI touchscreens and optimize cable routing. Firmware updates add features like auto-restart, batch recipes, and predictive alerts. These enhancements reduce manual errors and support proactive maintenance.
- Relay and breaker replacements for safety
- Neat cable management for quick access
- Firmware upgrades for advanced control logic
- Backup/restore functionality for fast recovery
Rebuild your control panels to enhance system reliability and simplify operation.
Electromechanical Overhauls
Revitalize your motors, drives, and sensors to maintain energy efficiency and accurate control.
Motor & Drive Refurbishment for Energy Savings
We rewind stators, replace bearings and seals, and rebalance rotors to restore motor efficiency. We tune variable-frequency drives (VFDs) for smooth torque and minimal harmonics. Refurbished motors can cut energy use by up to 20% and add 5–10 years of service life.
- Core inspections and stator rewinds for balanced performance
- High-grade bearings for reduced friction
- VFD parameter optimization for precise speed control
- Thermal imaging to verify safe operating temperatures
Refurbish your motors and drives today to lower energy costs and extend equipment life.
Instrumentation Calibration for Accurate Control
Precise sensors are critical for stable operation. We recalibrate pH, ORP, conductivity, turbidity, flow, and pressure transmitters to factory specs. Calibration certificates document accuracy within ±1% of full scale. Regular calibration prevents process drift and costly production losses.
- Accredited calibration with traceability
- On-site and bench calibration options
- Detailed calibration certificates for audits
- Sensor replacement guidance when tolerances exceed limits
Calibrate your instruments now to ensure accurate measurements and consistent product quality.
Structured Repair Process
Our proven repair process provides clear communication and reliable results.
Site Assessment & Diagnostic Testing
We start with a complete site survey. Field engineers inspect equipment in place or remove components for in-depth workshop evaluation. We review operation logs, run vibration analyses, and perform leak detection tests. This diagnostic phase pinpoints root causes and defines the exact repair scope.
- Vibration and thermal imaging to detect wear
- Leak tests with dye tracing and pressure checks
- Data-log correlation to identify failure patterns
- Root-cause analysis report with repair recommendations
Workshop & On-Site Execution
Repairs happen either in our fully equipped workshop or at your site with mobile workstations. We use OEM tooling, original drawings, and certified procedures to overhaul pumps, skids, and control panels. Our technicians work around your schedule to minimize plant disruption.
- Mobile fabrication units for on-site skid repairs
- Precision milling and welding booths for component rebuilds
- Clean rooms for valve and actuator reassembly
- Coordination with your safety and permit protocols
Engage GWT’s structured repair process to restore assets quickly and transparently.
Aftercare & Maintenance Services
We offer comprehensive after-repair support to keep assets performing.
Performance Testing & Documentation
Every repaired asset undergoes mechanical run tests, pressure and leak checks, and performance trials. We deliver an “as-refurbished” report with test results, measurement data, and final settings. This ensures you know exactly how your equipment performs.
- Flow and efficiency curves for each pump
- Pressure test certificates under operational loads
- Detailed performance logs with pass/fail criteria
- Recommendations for next preventive maintenance interval
Warranty & AMC Transition
Repaired equipment includes a warranty on parts and workmanship. We can enroll your assets into an Annual Maintenance Contract (AMC) for ongoing preventive services. AMC packages come with priority response, spare-parts discounts, and annual performance audits to prevent future issues.
- 12- to 24-month warranty options
- Tiered AMC levels to fit your budget
- Priority service for AMC clients
- Annual maintenance and efficiency reports
Secure long-term reliability by transitioning your assets into GWT’s AMC program.
