Indus Industrial Group supplies heavy-duty Horizontal Axially Split-Case Double-Suction Centrifugal Water Pumps engineered across suction/discharge sizes from DN150 to DN800 with electric motor and diesel engine drives from 37 kW to 800 kW according to ISO 9905 standards. Designed specifically for massive municipal water transmission trunks, Tigris and Euphrates river raw water intake stations, and regional booster complexes across Iraq, these pumps feature a double-suction enclosed impeller that balances hydraulic axial thrust forces naturally to zero. The horizontally split casing allows full rotor inspection simply by unbolting the top casing half without touching the pipe flanges or motor.

Major municipal potable water transmission pump stations, Tigris and Euphrates river raw water intake stations, power plant condenser cooling water circulation, large regional agricultural canal lifting, and refinery booster pumping across Baghdad, Erbil, Basra, Wasit, and Salah al-Din.
Axially Split-Case Double-Suction Centrifugal Pumps represent the premier heavy-duty engineering choice for high-volume municipal water transmission, raw river water extraction, and primary cooling circuits across Iraq. Governed by ISO 9905 and ISO 5199 standards, the pump utilizes a double-suction impeller where incoming water enters simultaneously from both sides of the impeller eye. This dual-flow entry completely balances hydraulic axial thrust forces mechanically, eliminating axial bearing load, reducing shaft deflection to near zero, and dramatically extending the operational lifespan of bearings and mechanical seals over decades of continuous 24/7 service.
The pump casing is split horizontally along the shaft centerline into two distinct halves: the lower half contains the suction and discharge nozzles, while the upper half acts as a removable inspection cover. Plant operators can inspect the impeller, wear rings, and bearings simply by lifting the upper casing half without disconnecting the suction or discharge piping or disturbing motor alignment. The enclosed double-suction impeller is cast from high-tensile bronze (CuSn10) or duplex stainless steel (AISI 316 / 2205) and dynamically balanced to ISO 1940 Grade G2.5, delivering whisper-quiet operation and hydraulic efficiencies reaching up to 88% to 90%.
Driven by high-power medium-voltage (3.3 kV / 6.6 kV / 11 kV) or low-voltage (400V) electric motors with heavy-duty sleeve or roller bearings, these pumps withstand the relentless operational demands of Iraqi river intake stations. Staged at the Erbil Heavy Plant Yard, Baghdad Central Depot, and Basra Port Corridor, Indus supplies complete split-case skids with baseplates, flexible couplings, control panels, and full EN 10204 3.1 inspection certification.
For flow rates above 500 m³/h, split-case double-suction pumps are far more reliable and energy-efficient than end-suction pumps. The double-suction impeller neutralizes axial thrust, preventing bearing burnout, while the horizontal split casing allows routine maintenance without unbolting massive DN400–DN800 pipes.
Indus supplies river intake split-case pumps equipped with replaceable high-hardness nickel-bronze or stainless steel casing wear rings and bronze/duplex impellers. The wear rings absorb abrasive wear and can be replaced inexpensively without replacing the major pump castings.
Yes. Indus supplies complete turnkey diesel-driven split-case pumping skids equipped with Cummins, Perkins, or Caterpillar industrial diesel engines, heavy-duty gearboxes, and automated start control systems for emergency river lifting and canal dewatering across Iraq.
