DAB DTRON3 45/90 Pump for Cisterns and Storage Tanks
The DTRON3 45/90 is a 7-inch submersible pump that houses its pressure controller, check valve and expansion vessel in one IP68 body. This US model, part number 60195642, runs on 115V, 60 Hz single phase. Its 0.8 HP motor draws about 9.7 A. Flow reaches roughly 26 GPM, with maximum head around 134 ft. Cut-in is set at 34.8 psi from the factory. Through the included Com Box, that point adjusts between about 22 and 51 psi. The outlet is 1-1/4 in NPT, and the power cable runs 49 ft with a plug on the end. A double mechanical seal protects the water-cooled motor, which sits inside an AISI 304 stainless jacket. The casing, filter and flow sensor are technopolymer. The pump measures 7.28 in across at its widest point and weighs about 25.6 lb.
Installing an Underground Tank Pump With Powerline Control
Growers pick this pump when irrigation water lives in a buried cistern, a rainwater vault or a large poly tank. It can work as deep as 39 ft below the water surface. The Com Box talks to the pump over the power line, so no control cable runs down into the tank. Plug the box into the same circuit, then set pressure and check alarms from the surface. Spacers in the box lift the intake 1.4, 1.6, 2.4 or 3.2 in off the floor to stay clear of sludge. An anti-cycling function ignores small leaks, so a weeping fitting will not start the motor again and again. Dry-run protection, thermal overload and a relief valve for frozen pipes come built in. An optional NFC float sensor drops into a pocket on the body for low-level cutoff. The pump suits clean water between 32 and 122°F, with up to 60 starts per hour. With the DOC68 base, it can also stand outside the tank on positive suction.
Key Features
- Com Box included: Set cut-in pressure and read alarms from a plug-in box at the surface, linked over the power line.
- Integrated controller: Pressure sensing, check valve, debris filter and expansion vessel live in the pump, so no tank or switch is needed.
- Anti-cycling logic: Small leaks are ignored, which spares the motor from constant short starts.
- Full protection set: Dry-run cutout, thermal overload and a relief valve for frozen pipes or water hammer.
- Adjustable intake height: Spacers keep the intake above settled sludge at the bottom of the tank.
- Surface option: Pairs with the DOC68 base for installation outside the tank on positive suction.
