Indus Industrial Group supplies heavy-duty Cast Iron Flanged Water Control Penstocks manufactured in circular and square orifice dimensions from DN300 (12") to DN1600 (64") for heads up to 20 meters. Built to British Standard BS 7775 and DIN 19569-4, these robust sluice penstocks feature high-grade spheroidal graphite ductile iron (EN-GJS-500-7) or grey cast iron bodies with precision-machined, hand-scraped bronze or stainless steel seating faces. Designed for municipal raw water intake headers, dam outlets, canal diversion barrages, and deep storm drainage wet wells across Iraq.

Ministry of Water Resources (MoWR) river barrages, canal regulator intake headworks, raw water reservoir drain outlets, and flood pumping station isolation in Wasit, Babel, Dhi Qar, Baghdad, and Nineveh.
High-capacity water control structures on Iraq's major rivers, irrigation barrages, and deep storm pumping stations require heavy-duty isolation equipment with massive structural rigidity to withstand decades of abrasive silt abrasion, floating logs, and extreme hydraulic forces. Indus Cast Iron Penstocks provide massive casting thickness and impact resistance that cannot be matched by lightweight sheet-metal fabrications.
The penstock body and sliding door are cast from spheroidal graphite ductile iron (EN-GJS-500-7), providing high tensile strength and resistance to mechanical shock. Both the frame and door incorporate dove-tailed, hydraulically pressed bronze or stainless steel sealing strips that are precision machined and hand-scraped to microscopic tolerances, creating a metal-to-metal seal that remains completely watertight under operating heads up to 20 meters without elastomeric seal degradation.
Equipped with adjustable wedge thrust blocks on both the top, bottom, and sides, the door is forced tightly against the frame at the final moment of closing, delivering zero-leakage shutoff in both on-seating and off-seating directions. Protected by thick fusion-bonded epoxy (min 300 microns) or heavy bitumen primer, Indus cast iron penstocks operate reliably for 50+ years. Staged in Erbil and Baghdad.
River water carries heavy sand, floating debris, and gravel that can tear or gouge soft rubber seals. Precision-machined bronze seating faces resist mechanical cutting and provide a self-lapping, smooth metal seal that lasts for decades.
Yes. Our circular penstocks are available with standard EN 1092-2 PN10/PN16 flanged backs, allowing direct bolting to pipe thimbles or flanged pipeline spools embedded in civil walls.
We supply intermediate stainless steel steady brackets with self-lubricating bronze or nylon bushings spaced every 2.0 to 2.5 meters along the stem to prevent buckling under compression when closing.
