DAB E.SYBOX Electronic Water Pressure System for Steady Irrigation Pressure
The E.SYBOX is an all-in-one booster pump that sits between a reservoir or cistern and the irrigation lines. It holds a steady set pressure no matter how many zones open at once. Inside the housing are a self-priming multistage pump, a water-cooled motor, an inverter drive, a pressure transducer and a flow sensor. The drive runs on 230V single phase, 50/60 Hz and draws up to 10 A at full load. Flow tops out at 32 GPM with a maximum head of 213 ft. The set point adjusts from 15 to 85 psi on the front display. It lifts water from as deep as 26 ft below the pump through 1-inch NPT suction and discharge ports. A built-in 2 L expansion vessel absorbs small draws, so a dripper bank starting up does not make the motor short-cycle. Running noise is rated at 45 dB, quiet enough to hang on the wall of a working grow room. The motor carries an IPX4 rating with Class F insulation, and the US unit is listed to UL 778 and CSA C22.2 Number 108. Its wetted parts carry NSF/ANSI 61 and 372 certification for drinking-water contact. Feed it clean, chemically neutral water only.
A Constant Pressure Booster Pump for Fertigation and Greenhouse Lines
Most growers fit one where a gravity tank or RO reservoir cannot push enough pressure to run emitters evenly down a long bench. Because the inverter speeds up and slows down with demand, the motor draws only the energy each moment calls for. That keeps pressure at the last emitter close to the first, even when a second zone opens mid-cycle. The display tilts for horizontal or vertical mounting, which helps in a tight utility closet beside the mixing station. Set the target pressure once, prime the pump through the filling plug, and it starts on demand from then on. Up to four units can pair wirelessly into one group that shares the load and rotates duty. That gives a larger greenhouse a backup pump without a separate control panel. Matching hardware from DAB includes the E.SYWALL wall bracket, the E.SYDOCK base and the E.SYTWIN station for two pumps. There is one honest limit to plan around. Sandy well water or a dirty catchment line will foul the check valve, so fit a sediment filter on the suction side. The pump also must never freeze with water inside it.
Key Features
- Inverter drive: Motor speed follows demand, so line pressure stays level and power draw drops when only a few emitters are running.
- Integrated sensing: A pressure transducer with temperature sensing and a flow sensor let the pump start, modulate and stop without a mechanical pressure switch.
- Built-in expansion vessel: The internal tank covers small draws and removes the separate pressure tank from most installs.
- Wireless grouping: Up to four units link without control cables to share duty and cover each other in larger fertigation rooms.
- Flexible connections: Removable gasketed caps let you choose the suction and delivery points, and the unit runs horizontal or vertical.
- Front service bay: The rotor shaft, filling plug and vessel valve sit behind one cover, so routine checks need no disassembly.
