Evolution Aqua Varipump 20000

Need strong, adjustable flow without wasting energy? The Evolution Aqua Varipump 20000 gives you full control over output, so you can match flow to your filter, waterfall or return line.

Designed for pond systems where flexibility matters, this variable flow pump lets you dial performance up or down as conditions change.

Why Choose the Varipump 20000?

• Adjustable flow to suit your filtration system
• Ideal for feeding filters, waterfalls or returns
• Helps reduce energy use by avoiding over‑pumping
• Designed specifically for pond use
• Compatible spare controller available (PP3692C)

Being able to control flow isn’t just convenient – it protects your filter from being overwhelmed and keeps your pond running efficiently.

Where It Fits Best

The Varipump 20000 is suited to:

• Gravity-fed filter systems
• Pump-fed filter systems
• Water features needing variable output
• Seasonal adjustment – lower flow in winter, higher in summer

If you’re unsure whether your system is gravity or pump-fed, check where the pump sits. Pump-fed systems push water into the filter. Gravity-fed systems draw water from a bottom drain into the filter before pumping it back.

Installation Notes

• Always install on a stable, level base.
• Keep the controller dry and protected from rain or splash.
• Ensure pipework is correctly sized to avoid restriction.

Pro tip: Use swept bends instead of tight 90° fittings where possible – smoother pipe runs mean better flow and lower energy use.

Safety First

• Disconnect from the mains before installation or maintenance.
• Protect all electrical connections from moisture.
• Use an RCD-protected supply for pond electrics.
