LS MDX Submersible Pump Drive
The LS MDX Submersible Pump Drive is a purpose-designed variable frequency inverter for direct submersible installation alongside borehole and deep-well submersible pumps, rated from 0.4 kW to 75 kW with an IP68 ingress protection rating certified for deployment at depths up to 50 metres below water level. Unlike conventional VFDs installed at the surface in aboveground panels, the MDX drive mounts directly on the pump motor assembly and descends into the borehole with it, eliminating the long motor cable runs between surface drives and submersible motors that cause voltage reflection, dV/dt damage to motor windings, and EMI emissions in conventional submersible pump VFD systems. The MDX-40kW model provides 40 kW of variable speed control using sinusoidal PWM output that reduces motor heating compared to conventional trapezoidal PWM inverters, extending submersible motor service life in the most demanding continuous-duty applications.
The MDX drive operates with a standard 380–480 V AC three-phase supply connected via the borehole cable to the submersible installation, and communicates with a surface-mounted MDX controller unit via the same power cable using power-line communication technology — eliminating the need for a separate signal cable in the borehole. The surface controller provides the operator interface, speed reference input, and SCADA connectivity via Modbus RTU or RS-485, enabling integration with irrigation system controllers, water authority SCADA systems, and remote telemetry units commonly deployed in Saudi Arabia's distributed water network. The operating temperature range of -10°C to +40°C water temperature covers Saudi Arabia's groundwater conditions, and the drive withstands hydrostatic pressure equivalent to 50 metres of water column, meeting the requirements of the deepest common borehole pump installations in the Kingdom.
Saudi Arabia's agricultural and municipal water supply is heavily dependent on deep borehole extraction from the Saq, Qasim, and Minjur aquifer systems, with thousands of boreholes operated by the Ministry of Environment, Water and Agriculture (MEWA) and private agricultural investors across the Kingdom. Variable speed control of borehole submersible pumps provides energy savings of 20–40% versus fixed-speed DOL-started pumps, critical given Saudi Arabia's high electricity costs and the long operating hours of agricultural irrigation systems. NWC and regional water companies are upgrading borehole pump systems with VSD technology as part of national water network efficiency programmes, and the MDX submersible drive eliminates the surface panel and long borehole cable installation costs that make conventional VFD retrofits prohibitively expensive for small to medium borehole sites.
Razz Middle East is the authorised LS Electric MDX Submersible Drive distributor for Saudi Arabia, supplying and installing these systems for agricultural, municipal, and industrial borehole applications. We provide borehole pump matching calculations, MDX sizing, and surface controller configuration services for new and retrofit projects. Our field service team performs MDX installation at pump assembly points before deployment and provides pressure-test verification of IP68 integrity before installation. SAR pricing with turnkey supply and installation options is available, and our warranty and service contracts cover both the surface controller and submersible drive units.

Key Features & Benefits
- IP68 certification to 50 metres depth allows direct submersible installation with the pump, eliminating long motor cables, dV/dt winding damage risk, and surface panel space requirements.
- Sinusoidal PWM output reduces motor heating compared to conventional trapezoidal PWM inverters, extending submersible motor service life in 24/7 continuous agricultural and municipal pumping applications.
- Power-line communication between the submersible MDX drive and surface controller uses the existing power cable, eliminating the requirement for a separate signal cable in the borehole.
- Variable speed control delivers 20–40% energy savings versus fixed-speed DOL pumping, providing rapid payback on the incremental cost of VSD technology for high-hours agricultural borehole applications.
- Surface controller provides SCADA connectivity via Modbus RTU for integration with irrigation automation systems and water authority remote telemetry units without additional protocol gateways.
- Hydrostatic pressure withstand equivalent to 50 metres water column and -10°C to +40°C water temperature range covers Saudi Arabia's full range of borehole conditions across aquifer systems.
Industrial Applications in Saudi Arabia
- Agricultural borehole submersible pump VSD control for irrigation of date palm, wheat, and vegetable farming operations across the Qassim, Hail, and Eastern Province agricultural regions.
- Municipal water supply borehole pump variable speed upgrades for NWC and regional water companies, reducing pumping energy costs and enabling flow-rate controlled well drawdown management.
- Industrial process water supply borehole pumps at desert-edge manufacturing facilities where variable speed control matches pump output to varying production water demand.
- Irrigation system submersible pump drives at NEOM and Vision 2030 planned city landscaping projects, where energy efficiency and remote monitoring align with smart city infrastructure requirements.
- Emergency water supply borehole pump systems at remote industrial sites and utility facilities where submersible drive installation eliminates the surface panel vulnerability to outdoor weather and vandalism.
