The Atlantic Water Gardens TidalWave L‑310 is a professional-grade low‑head axial pump engineered for very high-volume waterfall, stream and pond recirculation applications. Its direct-drive design delivers large flows through 3" plumbing while minimizing power draw and maintenance.

  • High-volume performance: Up to 13,500 GPH at 5' of head, optimized for wide waterfalls and heavy recirculation without excessive head pressure.
  • Reliable motor and protection: 1 HP (115V) motor drawing ~10 amps (≈1,105 W) with auto-cut thermal overload protection to prevent damage from low-water conditions.
  • Durable construction: Heavy-duty cast-iron and stainless-steel housing, double silicon carbide mechanical seals, and dual drive bearings for long service life.
  • Plumbing & dimensions: 3" MPT outlet, measures 9" L x 9" W x 19.25" H and weighs approximately 65 lb for stable installation.
  • Installation-ready: Supplied with long heavy-duty power cord (factory 30') and designed for fully submerged freshwater operation; maintenance is primarily keeping the intake screen clear.
  • Warranty & documentation: Backed by a 2-year manufacturer warranty; full L Series manual and service documents are available on the product page.

Designed for contractors and experienced pond builders, the L‑310 excels where massive, low-head flow is required. Use the included manual for installation, electrical requirements, and safe operation—always connect to a GFCI-protected circuit and avoid saltwater or pool installations. Regularly inspect the intake screen and seals to maintain peak performance.
