Evolution Aqua Varipump

The Evolution Aqua Varipump is a controllable pond pump built for medium to large ponds, koi systems, and filtration setups that need more flexibility than a fixed-speed pump can offer. Instead of running at one output around the clock, you dial in the exact flow rate you need at the push of a button, and the built-in display shows you the wattage the pump is drawing at that setting. It runs inline or fully submerged, and it's available in two sizes to match ponds from moderate water gardens up to large koi ponds and multi-filter systems.

Why a Variable Speed Pump Makes Sense

A fixed-speed pump runs at one output whether your pond needs it or not, which usually means paying to move more water than necessary. The Varipump lets you match output to the season, the filter load, or how much waterfall noise you want at any given time, then dial it back down to save on electricity without shutting the system off. Because you can see the wattage in real time, it's straightforward to find the lowest setting that still keeps your filter and waterfall running the way you want.

Key Features

Push-Button Flow Control with Live Wattage Readout

The onboard controller adjusts pump output from a full stop up to maximum flow, and it displays the power draw at whatever level you've set it to. That makes it easy to fine-tune the pump for your actual system instead of guessing at a fixed-speed model that might be oversized or undersized for the job.

Quiet, Reliable Motor

Evolution Aqua built the Varipump around a motor designed for continuous duty, and it runs noticeably quieter than a lot of fixed-speed alternatives, particularly when it's throttled back from full output. That matters if the pump or filter housing sits anywhere near a patio or seating area.

Flexible Installation – Inline or Submerged

The Varipump can be installed submerged directly in the pond or plumbed inline as a dry-mounted external pump feeding your filtration system, and it can be mounted vertically or horizontally depending on how your plumbing runs. That flexibility makes it a fit for a wider range of pond and filter layouts than a submersible-only or external-only pump.

Sized for Big Ponds and Demanding Filters

Both Varipump sizes are built to handle serious flow. Even the smaller model moves over 2,600 gallons per hour, and the larger model pushes past 5,000 gallons per hour with enough head height to run a raised filter, a multi-bay system, or a waterfall with real elevation.

Choose the model based on the flow rate and head height your pond and filter system need.

Which Varipump Size Do You Need?

The Varipump 10000 is the better fit for medium-sized ponds and water gardens, with a 1½-inch inlet and outlet, up to 2,640 GPH, and up to 10 feet of head, which covers most single-filter setups with a modest vertical lift. Step up to the Varipump 20000 if you're running a larger koi pond, a bigger filtration system, or a waterfall with more elevation. It has a 2-inch inlet and outlet, moves up to 5,280 GPH, and handles up to 18 feet of head, giving you room for longer pipe runs and taller waterfalls without losing performance.

What's Included and How It Installs

Each Varipump ships with hosetail fittings and its digital controller, which connects to the pump with a 30-foot cable and runs from the controller to the wall plug with a separate 6-foot cable, giving you room to mount the controller somewhere convenient and dry. Whether you install it submerged in the pond or set it up as a dry-mounted external pump, an instruction manual is included to walk you through setup, and the controller's display will show troubleshooting fault codes if something needs attention.

A Pump That Adapts to Your Pond, Not the Other Way Around

Whether you're running a water garden with a single waterfall or a full koi filtration system with multiple stages, the Evolution Aqua Varipump gives you the flow control to match the pump to the job instead of settling for one fixed speed. With two sizes covering ponds from moderate to large, and the option to install it submerged or externally, it's built to fit into whatever setup you're running.
