USES: The FS serie submersible electropumps is widely used in handcrafts and industry to dispose of clean or dirty water or other liquids. They are also suitable for pumping aggressive media. It is strictly prohibited to use the electropump for lifting combustible fluids. It is also prohibited to position or to remove the pump by means of 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. 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 electric pumps are completely in stainless steel AISI 304, stainless steel motor shaft, 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 silicon carbide/alumina. 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 0,37 kW to 1,5 kW with a 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 three-phase electropumps.
