Construction Features of the Pump
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).
Construction Features of the Motor
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.
Features of the Electronic
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.
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.
