Little Giant EC-1U-DV Series Undermount Condensate Pump

Applications

The EC-1U-DV model is a slim undermount unit that installs easily and neatly underneath equipment. It is designed to automatically remove condensate water that drips from wall mount ductless air conditioners.

The EC-1U-DV model accommodates multiple electrical requirements within one pump. The DV suffix indicates that the pump is capable of operating from a wide range of supply voltage to maintain consistent pump performance.

Performance Data

Performance Data for 110-240 V, 50/60 HZ

The performance chart illustrates the relationship between flow rate and head pressure. The chart displays flow in liters per hour (LPH) on the y-axis against head in meters on the x-axis, and also shows flow in gallons per hour (GPH) on a secondary y-axis against head in feet on the x-axis. The curve indicates that as the head increases, the flow rate decreases. Based on the provided specifications, at 0 feet (0.0 meters) of head, the flow is 2.7 GPH (10.2 LPH). At 1 foot (0.3 meters) of head, the flow is 2.5 GPH (9.5 LPH). At 10 feet (3 meters) of head, the flow is 1.5 GPH (5.7 LPH), and at 20 feet (6.1 meters) of head, the flow is 1.2 GPH (4.5 LPH).

Note: Do not operate above 33 feet (10 meters) total head.

*Tested under conditions assumed consistent with competitors' published sound ratings.
