Description

The Evolution Aqua Varipump range has been designed for koi ponds, gravity systems, pump fed filters, drum filters, moving beds, waterfalls and large water features where reliable adjustable flow is required.

Unlike fixed speed pond pumps, the Varipump range allows the output to be adjusted to suit seasonal demand, filtration requirements and energy consumption. This gives better control over pond turnover rates while helping reduce running costs.

Each pump is supplied with an electronic variable speed controller allowing quick flow adjustments without changing pipework or restricting flow with valves.

Suitable for both submerged installation and dry mounted external installation, the Varipump range is ideal for use with Nexus systems, bead filters, moving bed filters, drum filters and custom filtration setups.

Common applications include:

✔ Koi ponds
✔ Pump fed filtration systems
✔ Gravity return systems
✔ Drum filters
✔ Moving bed filters
✔ Waterfalls and streams
✔ Quarantine systems
✔ Large ornamental ponds
