In water conservancy, municipal drainage, and wastewater treatment, managing water flow and preventing backflow requires robust isolation gates. Kairun Pump manufactures heavy-duty sluice gates (also known as penstocks) designed to regulate fluid flow and seal pipeline or channel systems. Whether applied in water treatment intake channels, municipal storm reservoirs, or agricultural irrigation canals, our gates offer reliable structural integrity to withstand high hydrostatic pressure. We focus on durable cast iron and steel construction, precise sealing surfaces, and versatile actuation systems to lower your long-term operational costs.
We supply a diverse range of water control gates configured for open channels and wall-mounting applications:
Cast Iron Sluice Gates (SYZ Series): Highly resistant to corrosion and deformation, these gates are ideal for deep-water installations, sewage treatment plants, and seawater environments.
Steel Sluice Gates (SFZ Series): Built with premium structural steel or stainless steel, offering high tensile strength and flexible sizing options for large-span channels and flood control projects.
Channel Gates & Penstocks: Designed for direct embedding in concrete open channels, utilizing sliding mechanisms to isolate flow efficiently.
Flap Gates (Non-Return Gates): Gravity-activated valves that allow free outward flow while preventing backflow from high water bodies or tidal waves.
Corrosion-Resistant Materials: Standard gates are fabricated from high-grade cast iron, carbon steel, or stainless steel (SS304/SS316) to withstand aggressive wastewater and chemical environments.
Reliable Sealing Performance: Equipped with high-performance copper alloys, brass, or elastomeric (EPDM) sealing faces to achieve tight, low-leakage isolation.
Flexible Actuation Methods: Compatible with manual handwheels, bevel gears, pneumatic cylinders, and electric actuators, allowing seamless integration with automated plant control systems.
A: The SYZ series consists of cast iron sluice gates, which are inherently more corrosion-resistant and highly suited for sewage systems and deeper water depths. The SFZ series comprises fabricated steel or stainless steel gates, which offer greater tensile strength and are typically preferred for large-scale channel gates where custom dimensions are required.
A: Yes. For corrosive applications, we recommend stainless steel (SS304 or SS316) construction or specifying cast iron gates with specialized epoxy coatings and bronze sealing rings to prevent rust and maintain structural integrity.
A: Absolutely. Our gates can be supplied with electric, pneumatic, or hydraulic actuators that are fully compatible with local or remote SCADA control systems. We can also provide manual override handwheels to ensure operation during power interruptions.
