DAB DTRON3 35/120 Pressure Pump for Tanks and Cisterns
The DTRON3 is a submersible pressure pump with its controller, check valve and expansion vessel built into one stainless-jacketed body. This 35/120 model carries DAB part number 60197703 and runs on 115V, 60 Hz single phase. The 0.8 HP motor draws about 8.8 A and moves up to 32 GPM, with a maximum head of 146 ft. Water leaves through a 1-1/4 in NPT outlet, and the plug-in power cable runs 49 ft. Factory cut-in pressure is 34.8 psi, adjustable from roughly 22 to 51 psi through the supplied Com Box. A 0.04 L expansion vessel absorbs small draws, so a slow drip does not start the motor. The pump can sit as deep as 39 ft below the water surface. Its body is 7.28 in at the widest point and weighs about 25.6 lb. Spacers in the box set the intake 1.4, 1.6, 2.4 or 3.2 in above the tank floor. It handles clean water from 32 to 122°F and allows up to 60 starts an hour.
Running a Submersible Electronic Multi-Impeller Pump From a Cistern
Growers fit one where irrigation water is stored below grade, such as a rainwater cistern, an RO holding tank or a buried storage vault. Settings travel over the power line, so the Com Box plugs straight into the same outlet as the pump. No signal cable runs down the tank. Choose the tallest spacer that still leaves the pump covered, which keeps the intake above settled sediment. Built-in protections cover dry running, frozen delivery pipes and motor overload. An anti-cycling function stops the motor hunting when a fitting leaks slightly. DAB also offers an NFC float switch that drops into a pocket on the pump body for low-water cutoff. With the DOC68 base, the same pump can run as a surface unit installed below the water level. The limits are clear, though. It is built for clean water, so a silty pond or sandy well will wear the impellers and clog the filter.
Key Features
- Controller built in: Pressure sensing, start-stop logic and protections live inside the pump, so no pressure tank or switch box is needed.
- Com Box over the power line: Set the cut-in pressure and read alarms from a plug-in box, with no extra wiring down the tank.
- Integrated check valve and filter: The pump body includes a non-return valve and debris filter, which simplifies the plumbing at the tank.
- Adjustable intake height: Supplied spacers lift the intake off the tank floor so sediment stays where it settled.
- Full protection set: Dry-run, anti-cycling, anti-freeze relief and thermal overload protect the motor without extra hardware.
- Flexible installation: Runs fully submerged, or as a surface pump below water level with the DOC68 base.
