Seltz D is the newly revealed official name for the Varia Flow pump that Hydor has slowly been pulling back the curtain on since last fall at MACNA. The first thing we learned about the Seltz D is that it was in fact not a DC controllable pump, but an AC version which should perform identically as far as reefers are concerned.
The Hydor Seltz D uses an innovative 6-pole motor to achieve high water flow efficiencies and has a controller built inline to adjust speed and to initiate the feed timer for five minute pauses. One thing you won’t get with this AC motor design is any external speed control via 0-10 volt input but you also won’t have to find a place for a DC power supply, or worry about the failure of that component.
Just three weeks ago we got some official specifications on the three models and their respective flow rates, and today we discover how much this novel pump design will cost. The Seltz D 1600 will carry a suggested retail of $181.95, the Seltz D 2400 will be $197.95 and the largest Seltz D 3200 will top out at $229.78.
