USES: The GXB serie submersible electropumps is widely used in household systems,in handcrafts and industry to dispose of clean or slightly dirty water or other liquids. It is strictly prohibited to use the electropump for lifting combustible fluids. It is also prohibited to position or to remove the pump by the electric cable. Maximum temperature of the pumped fluids: - Continuous duty: 50°C. Minimum pumping level: 10 cm. above the pump body. Maximum fluid density: not higher than 1.100 Kg/m3. Permissible draught of water: 5 mt. The electropumps can pump fluids containing solids with a diameter that allows them to pass the impeller (see the technical chart).

CONSTRUCTION: The components have been accurately selected in order to achieve maximum reliability and long life even in the hardest applications. The materials of which the electropump is made are: motor casing, motor cover, motor bracket, base holder in AISI 304 stainless steel, AISI 316 stainless steel motor shaft, pump body and impeller in G20 cast iron, while the gaskets are made of nitrile rubber (oil-resistant). The bearings are of high quality and need only be greased after a long period of operation. Mechanical seal made of ceramic-graphite. The top seal has a lip (oil seal).

ELECTRIC MOTOR: The two-pole electric motor, single-phase or three-phase has a die-cast aluminium rotor, immersed in a dielectric anti-oxide oil bath. The power available ranges from 0,75 kW to 1,5 kW. Single-phase voltage of 230-240 V. 50 Hz and a three-phase voltage of 230/400 V. 50 Hz. The motors have been designed to give maximum rated power with a variation of +/- 5% of the rated frequency or voltage. They are completely watertight, insulation class F, degree of protection IP68. The single-phase motors are fitted with thermostat-controlled safety microswitches to avoid undesirable damages to the motor in the event of blocking of the impeller. The motor is cooled by the same fluid in which the electropump is immersed. The standard equipment includes 10 metres of cable H 07 RN-F and a Schuko plug, while three-phase versions are supplied with free terminals. The user must provide protection for threephase electropumps.
