Product Overview


Option 1: Includes pump only.

Option 2: Includes Pump Base (DOC68) with 1 1/4" threaded side inlet connection and required Adapters for 2" Floating Filter to connect

7” multi-stage electronic pump with VFD (variable frequency drive) for clean water designed for use in wells, cisterns or tanks. Usable submerged, partially submerged or on the surface (with the appropriate accessory). It is suitable for pressurization, reuse of rainwater and activities. gardening and irrigation in domestic and residential environments. The pump can also be installed horizontally. Equipped with PLC (PowerLine Communication)and Wi-Fi technology. If combined with an identical pump two Esydivers can work in twin mode one in place of the other or in support mode when the system requests are higher than what can be supplied by a single pump. Available in version X with 1 “union and kit X which includes the 3.3 ft / 1 meter suction pipe and float to prevent the suction of impurities from the bottom. The entire pump is IP 68 certified. With the DOC68 accessory (supplied separately) it becomes an IP 68 surface pump to be used under the leaf.

Technopolymer pump body to resist corrosion and oxidation. Integrated non-return valve. Integrated debris filter. Overpressure valve to resist the formation of ice and protect from water hammer. On the pump body there is a air-vent valve that improves priming during the first installation or in the event of emptying the tank/ well, and a stainless steel handle to move the pump. Integrated 0,04 liter expansion vessel sized to prevent the pump from cycling in the event of small leaks and to compensate for water hammer. No maintenance or recharging is required. The coupling between the three impellers in technopolymer, the floating ring and the smoothing disc both in stainless steel allow a limited wear of the hydraulics and a more precise alignment of the components. Suction height can be adjusted using the appropriate accessory (included): 1.4” 1.6” 2.4” 3.2” (3.5, 4, 6 or 8 cm).

High efficiency Permanent Magnet submersible motor cooled by the pumped liquid. hydraulic side of the motor shaft in AISI 303 stainless steel. Double mechanical seal in oil chamber where the seal on the motor side is subjected only to submersible pressure 14 psi (1 bar), while the other side is subjected to operating pressure up to 80psi (5.5 bar) ensuring that the pump is watertight. Start-up capacitor and integrated anti-overheating motor thermal protection. Quick coupling/release cable to facilitate installation inside tanks or cisterns. Tear-off power cable connection.

The electronic operation allows the pump to start and stop autonomously it is able to keep the working pressure adjustable from14 to 80 psi (1 to 5.5 bar), the variable frequency drive for operation according to the system requirements and protects against dry running. NFC (Near Field Communication) pocket for the use of a float sensor (supplied separately) which can be connected without opening the pump maintaining a watertight seal. Thanks to the PLC communication technology, the pump transmits data through the power cable to the DConnect Box 2.

Thanks to the DConnect Box 2 and the DConnect app it is possible to check and manage the system pressure, alarms and the amount of residual water in the tank directly from your smartphone or tablet. DConnect Box 2 supplied as standard.

In order to increase the set-point pressure (factory setting is 40-45 PSI) on the pump, you must have the pump and D-Connect Box on the same 230V circuit. This can either be accomplished by plugging them both into the same 230V receptacle or by cutting the plugs off of both cables and wiring them together with wire nuts directly to the single phase, 230V power source. This allows communication between the pump and controller to occur.
You must connect to the pump DConnect Box using WIFI and Bluetooth in order for the DAB D-Connect app (installed on Android or iPhone) to interface with the DConnect Box. The 2nd video below shows how to change the set point pressure.
It's usually best to take care of all of this in an indoor, WIFI friendly environment rather than waiting and attempting to do it at the installation job site. It will save you from potential frustration if you are unable to connect while on site.
Note that the pump will operate without the control box but will only do so at the preset factory pressure setting (approx. 40-45 PSI) unless the installer increases the pressure setpoint in advance. The app tends to work best with an Android device.
