DTron 3

DTron3 is a 7” submersible electronic multi-impellers pump for clean water designed for use in wells and tanks. It can be used submerged, partially submerged or on the surface (with the appropriate accessory). It is suitable for use in domestic and residential environments for pressurization, rainwater reuse, gardening and irrigation activities. The pump can be installed even horizontally. Equipped with PLC (PowerLine Communication) technology which allows to communicate with the external controller Com Box supplied as standard. It is also available in version X with 1” NPT Female inlet for connection to a floating suction hose to prevent the suction of impurities from the bottom. The entire pump is classified IP 68, with the DOC68 accessory (supplied separately) it becomes an IP 68 surface pump to be used under the level of the water. On request a certified version for drinking water is available. Integrated expansion vessel, no additional expansion vessel is required.

CONSTRUCTION FEATURES OF THE PUMP
Technopolymer pump body to resist corrosion and oxidation. Integrated check valve. Integrated debris filter. Overpressure valve to resist to the formation
of ice in the piping and to 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. Technopolymer handle to move the pump. Integrated 0,04 liter expansion vessel sized to prevent the pump from
cycling in the event of small leakages and to compensate in case of water hammer. No maintenance or recharging is required for the integrated vessel.
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. Suction height can be adjusted using the appropriate accessory (included): 1.4” - 1.6” - 2.4’ or 3.2“ (3.5 - 4 - 6 or 8 cm)

CONSTRUCTION FEATURES OF THE MOTOR
Asynchronous submersible water cooling motor. The hydraulic side of the motor shaft is in AISI 303 stainless steel. Double mechanical seal in oil
chamber ensuring the pump watertight. Capacitor and integrated anti-overheating motor for thermal protection. Quick coupling/release cable to facilitate
installation inside tanks. Anti tear-off power cable connection.

FEATURES OF THE ELECTRONIC
The electronic operation allows the pump to start and stop autonomously, by the system requirements and protects against dry run. NFC (Near Field
Communication) pocket for the use of a float sensor (supplied separately) connectable without opening the pump. Thanks to PLC communication technology,
the pump transmits data throughout the power line. The controller Com Box (included) allows to set the cut-in pressure and to control the alarms. The ANTIBURPING
protection protects the pump from false starts in the event of gurgling water. The ANTI-LEAKEAGE protection intervenes in case of leakages in the
systems.
