Product Overview

Note: Fixed shipping rate not available in Hawaii or Alaska.

Pairing 2 of the DAB E.SYBOX MINI 3 pumps together doubles the flow rate while maintaining the same pressure as is produced by a single MINI 3 pump. In order to calculate flow and pressure for 2 pumps used in tandem, simply refer to the MINI 3 performance curve chart below, and double the flow rate that is shown. For example, a single DAB E.SYBOX MINI 3 variable speed pump will produce 10 GPM (Gallons per minute) at 58 PSI. This E.SYBOX MINI 3 - Double Booster Pump System Kit will essentially produce 20 GPM at approximately 58 PSI, doubling the flow rate but not the pressure.
E.SYBOX MINI 3 - Double Booster Pump System Kit also comes with everything shown including: (Qty 4) 1" x 24" Stainless Steel Flex Hoses with quick disconnects, (Qty 9) 1" x 3" SCH80 PVC Nipples, (Qty 2) 1" Stainless Steel Female Threaded Y Connectors, and (Qty 1) 1" PVC/Stainless Steel Ball Valve w/ SS Ball and SS Handle.
Note: When running the E.SYBOX MINI 3 - Double Booster Pump System Kit, one of the two pumps must be set at 7 PSI below the other. Set a calendar reminder to alternate the pumps' pressure settings every 6 months. This will evenly distribute the pumps' workload.
**Spud Wrench:  The stainless steel connections on the DAB MINI3 and E.SYBOX pumps, it requires a radiator valve spud wrench (shown in pic #4 & 5) to tighten the fittings properly, and you'll want to use stainless steel thread tape or stainless steel pipe dope.

Note that this is the E.SYBOX MINI3. It's the newest, updated version that will be the only 1 HP in the E.sybox line moving forward. One of the differences in the MINI3 compared to the original MINI is that an additional impeller has been added to the MINI3. The original MINI has 2 impellers, and the MINI3 has 3. It's also important to note that the original MINI does not have connectivity capabilities when the D-Connect is offered. The E.sybox MINI3 is compatible with the D-Connect.

Thanks to the technological know-how developed during more than 40 years, DAB PUMPS is proud to introduce to the market the E.SYBOX mini 3, this is the most compact electronic pressurization system in the world.

Revolutionary, integrated E.SYBOX mini 3 provides a new installation experience and maximum comfort during use. E.SYBOX mini 3 benefits from the most advanced DAB technologies to ensure a consistent pressure based on actual needs, and therefore an optimization of energy consumption. E.SYBOX mini 3 has a different appearance than any other booster set and is small and completely integrated. Once you install and use it, you realize that the real difference is in the comfort and performance.

E.SYBOX mini 3 uses the most advanced DAB technologies to create constant pressure according to the system demands and thus an optimization of energy consumption.
The new 3-rotor model ensures further noise reduction and energy consumption.
Managing the water pressure in your home has never been so simple and quiet. E.SYBOX mini 3 is the DAB compact automatic booster system for the water supply of a single dwelling. E.SYBOX mini 3 guarantees the comfort of constant pressure (Pressure Set Point adjustable from 15 up to 79 psi) inside the system. Suitable for use with drinking water, in domestic systems, and in gardening applications. E.SYBOXmini³ does not require any additional components for its installation.

Operating range:

 capacity up to 22 gpm (80L/min); head up to 183 ft (56 m) - (80 psi)


 Dual Voltage 115/230V
 9.6 Amps at 115V
 4.8 Amps at 220V

How to wire the MINI 3 to a 230V circuit

  • The MINI 3 comes with a 115V plug for 115V installations and use. However, since the pump is dual voltage 115/230V, you may use 230V power if you prefer, and making the change to 230V is easy. You simply cut the 115V plug off of the cable and either 1) connect a 230V plug that matches your 230V receptacle and plug it in or 2) wire it directly to the 230V power source.
  •  The pump automatically senses the voltage and adjusts itself accordingly.

 Note: All of DAB's ESYLINE pumps (MINI 3, E.SYBOX, and DIVER) are capable of running on 208V power as well.
