The Atlantic-Oase Waterfall Pumps are purpose-built for creating strong, steady flows in waterfalls and pond-free systems. Using synchronous magnetic technology, they combine reliable performance with low energy consumption, making them a dependable choice for continuous operation. These pumps are engineered to thrive even in tough water conditions, with coated magnetic rotors that resist scaling and wear in hard water environments.

Maintenance is designed to be quick and straightforward. The volute can be removed without tools, and the self-cooling rotor chamber flushes debris automatically to help prevent overheating. With a built-in grounding plate for safety, these pumps deliver the peace of mind and long-term durability needed for both water gardens and pond-free waterfalls.

Why Choose Atlantic-Oase Waterfall Pumps?

  • Reliable performance: Engineered for continuous duty in waterfalls and pond-free systems.
  • Energy efficient: Synchronous magnetic design reduces operating costs.
  • Hard water ready: Coated rotors resist scale and poor water quality damage.
  • Low maintenance: Tool-free access and self-flushing design simplify cleaning.
  • Safe design: Grounding plate prevents stray current for added safety.

PRO TIP

When installing a waterfall pump, position it in a clean, dedicated pump vault or intake bay. This reduces exposure to heavy debris, improves cooling efficiency, and extends pump life - especially in pond-free systems where reliability is critical.
