The AutoAqua DP-200 ATO DC Refill Pump is a replacement/spare DC pump for AutoAqua auto top-off systems — the part to order if your ATO's pump has worn out or stopped priming reliably. Note this is the pump component itself, not a standalone ATO system; overflow and dry-run protection comes from the sensor and controller it's paired with. Model: DP-200 Max head: 250cm (8.2ft) Max flow: 74 gph (280 lph) Power: 4.8W @ 12VDC Rated lifetime: 30,000 hours Cable length: 180cm (6ft) Connector: 5.5mm x 2.5mm male DC pump connector A worn or failing pump is one of the most common reasons an ATO system stops keeping up with evaporation — swapping in a fresh DP-200 is usually faster and cheaper than replacing the whole controller.Compatible with: AutoAqua ATO systems specifying the DP-200 pump.
