Product description
Atlantic-Oase L-Series Direct Drive Axial pumps are engineered to deliver massive volumes of water at low head pressure, making them the premier choice for wide waterfalls and large-scale water features. Available in 1/2 HP (L-305) and 1 HP (L-310) configurations, these pumps provide flow rates up to 14,200 GPH. Built with a rugged cast iron and stainless steel housing, the L-Series features double silicone carbide mechanical seals and dual drive bearings for industrial-grade durability. With a 3-inch MPT outlet and integrated thermal overload protection, these pumps offer high-efficiency performance for demanding, high-flow aquatic environments.
Engineering Excellence in Axial Flow
The L-Series stands out in the industry for its ability to move water economically. Unlike standard centrifugal pumps, the axial design is optimized for "high-volume, low-head" applications. This means you get the massive splash and wide sheets of water required for professional-grade waterfalls without the extreme energy costs typically associated with high-pressure pumps.
Built for Industrial Longevity
Atlantic-Oase has prioritized structural integrity in the L-Series. The combination of heavy-duty cast iron and stainless steel ensures that the pump body resists corrosion and physical wear in continuous-duty cycles. Internally, the dual drive bearings and double silicone carbide mechanical seals significantly reduce friction, which not only extends the motor's lifespan but also maintains whisper-quiet operation.
Advanced Motor Protection
To safeguard your investment, each L-Series pump is equipped with thermal overload protection. This system automatically shuts down the motor if it detects low-water conditions or overheating, preventing permanent damage. The 3-inch male threaded outlets (MPT) simplify the connection to large-diameter plumbing, reducing friction loss and ensuring maximum flow from the moment of installation.

💡 Expert Installation Tip:
To achieve the best performance and quietest operation, mount the L-Series pump on a solid, level base slightly below the water surface. Using flexible, vibration-reducing tubing for your initial plumbing connection will help isolate motor noise and prevent stress on the 3" threaded outlet, significantly extending the life of your plumbing system.
