DAB ESYBOX DIVER 55/120 for Constant Pressure From a Tank
The ESYBOX DIVER 55/120 is a 7-inch submersible pump with a built-in inverter that changes motor speed to hold a steady pressure. It runs on 230V single phase at 50/60 Hz, with a motor rated about 1.3 HP. Flow reaches up to 31.7 GPM, and maximum head is about 180 ft. The pressure set point arrives at 43 psi and adjusts from 14 to 80 psi. Water leaves through a 1-1/4 in NPT threaded outlet. The 49 ft power cable ends in a NEMA 6-15P plug. A check valve, debris filter and 0.04 L expansion vessel sit inside the body. The pump casing and impellers are technopolymer, with an AISI 303 stainless motor shaft. It carries an IP68 rating with Class F insulation. Listings include UL 778, CSA C22.2 Number 108-14, NSF/ANSI 61 and NSF/ANSI 372.
Running a Variable Speed Submersible Pump in a Grow
Constant pressure matters when one tank feeds zones of very different sizes. As valves open, the motor speeds up, and it slows again as they close. That keeps emitter output even and trims energy use during light draws. The standard version installs as deep as 39 ft below the water surface. DAB lists a minimum water level of 1.38 in and a minimum suction depth of 4.33 in. Solids larger than 0.08 in should be kept out of the supply. Data travels over the power cable to the included DConnect Box 2, so no signal wire runs into the tank. From the app, growers can check pressure, read alarms and see how much water remains. Protections cover dry running, small-leak cycling and frozen delivery pipes. The pump handles clean water from 32 to 131°F and allows up to 60 starts per hour.
Key Features
- Inverter speed control: Motor speed tracks demand, so pressure stays steady whether one zone or several are open.
- Wide pressure range: The set point covers 14 to 80 psi, which suits drip, micro-spray and household supply.
- DConnect Box 2 included: Pump data travels over the power cable to the box for app monitoring and alarms.
- Potable water listings: NSF/ANSI 61 and 372, UL 778 and CSA listings suit supplies shared by people and crops.
- Built-in hydraulics: Check valve, debris filter and expansion vessel live inside, so no pressure tank is needed.
- Surface option: Pairs with the DOC68 base to run outside the tank on positive suction.
