Evolution Aqua Varipump 20000
The Evolution Aqua Varipump 20000 is a powerful, controllable pond pump delivering up to 20,000 L/h. Energy-efficient, quiet and fully adjustable, it’s ideal for large ponds, waterfalls and high-demand filtration systems.
Product Description
The Evolution Aqua Varipump 20000 is a heavy-duty, variable-speed pond pump built for serious koi ponds and large filtration setups. With a maximum flow rate of 20,000 L/h, it provides the strong, consistent water movement required for premium systems such as Nexus, multi-bay filters, drum filters and large waterfall features.
Featuring a robust six-pole, three-phase motor, the Varipump 20000 combines high power with smooth, quiet operation. The included digital controller allows precise adjustment of the flow rate, letting you reduce energy consumption when full power isn’t needed. This controllability makes it ideal for seasonal flow adjustments, feeding cycles, and fine-tuning filtration performance.
Designed for versatility, the pump can be installed submerged in the pond or used dry (below water level) in a filter house. Long cable lengths make installation simple, while the solid construction, large inlet/outlet connections and durable components ensure reliable, long-term operation—even under continuous use.
Whether you’re running a large koi pond, a high-flow filtration system or a substantial waterfall, the Varipump 20000 delivers the power, efficiency and control required for demanding aquatic environments.
