Peristaltic Pump for Auto Top-Off

Newly redesigned for easier tubing changes with our custom laser engraved cover.  We completely re-engineered our peristaltic pump to make it the quietest pump of its type on the market, we challenge you to find a quieter or more reliable peristaltic pump!

One of the most frequently asked questions concerning our popular Top-Off Kit is "which pump works best?"  While we designed the basic kit to work with just about any water pump, we have always felt that peristaltic pumps are the best choice when moving small amounts of water.  Quality peristaltic pumps, also known as dosing pumps, provide very consistent flow rates and require little maintenance.  Their anti-siphon characteristic is an important feature concerning evaporation replacement.  This allows you to place your top-off reservoir anywhere in relation to your tank, sump, or kalk stirrer.  With traditional water pumps, situating the top-off reservoir above the level of your sump could lead to siphoning and overflow unless specifically designed otherwise.  With a peristaltic pump, you get a precise amount of water delivered exactly where you want it, and not a drop more.  Our pump is capable of delivering water at up to 20 feet of head pressure.  That's several stories up or down, and hundreds of feet horizontally.  No need to have your top-off reservoir under your tank.  You can keep it out in the garage on the other side of the house!

Auto Top Off pump

So far, very good. I have only had it running a week, but my sump is staying at the proper level and I have not heard the pump. Solid build, easy to mount. I also have the Avast kalk stirrer and ATO sensor assembly. Great products that look good too. Pump might be excellent, but will have to see how long it lasts.

Easy Install & Quiet

Because tank in the bedroom needed a quiet ATO which Avast certainly delivered. I had a small vibration issue through the stand easily silenced by installing a rubber gasket behind the pump.....ultra quiet.

Peristaltic ato pump

This pump doesn't pump very much water at all . If you have a tank that has a open top and you have a lot of evaporation this pump sucks . It might make a good dosing pump but that's it .
