ACCESSORIES

Wastewater treatment and purification, seawater treat-ment and desalinisation, water treatment in textile, tan-ning and metallurgical industries, pumping of thermal waters and in petrochemical plants, industrial chemical processes.

• Surface centrifugal monobloc pump with open im -peller suitable for handling aggressive liquids and hydrocarbons without solid particles.

• Impeller and pump casing in AISI 304/316 high thickness stainless steel, which ensure a higher mechanical and corrosion resistance.

• The pump casing is internally and externally poli-shed to ensure the highest level of hygiene and low number of welds ensures higher hydraulic efficiency and higher reliability.

• Single mechanical seal.• Available the version with double mechanical

seal suitable for treatment of potentially explo-sive liquids (our ID EX series).

• Certifications ATEX II 2G Ex h IIC T3 Gb ATEX II 2D Ex h IIIC T120°C Db

• ATEX asynchronous motor, 50 Hz, FL EX C series 2 poles 2800 rpm, FL EX D series 4 poles 1400 rpm.

• II 2G o II 2D protection. • Working voltage: 230V/400V. • Ambient temperature: min -20 °C – max +40 °C.

• The pump cannot operate in dry conditions.• Pumped liquid temperature: min 0 °C – max +120 °C.• All the protections can be chosen in accordance

with the instruction manuals supplied with the pump and with the operating conditions, according to the current potentially explosive atmospheres installa-tion rules.

• Control panel.• Intrinsically safe module with ATEX supply circuit

for ATEX electronic level transmitter and ATEX level regulator.

• ATEX (or ID ATEX) electronic level transmitter.• ATEX level regulator with 5, 10 or 20 m of electric

cable.• Motor-pump coupling with double seal system with

an oil chamber and thermal protection.• Stainless steel carriage with conductive wheels,

ATEX switch.
