Impeller pump TR series

waterelectricsubmersible

THE TR SERIE OF TWO-POLES SUBMERSIBLE ELECTROPUMPS IS WIDELY USED FOR THE LIFTING OF CIVILIAN AND INDUSTRIAL WASTES, SLAUGHTER HOUSES, STABLES AND SEWERS. USES: The TR serie of two-poles submersible electropumps is widely used for the lifting of civilian and industrial wastes, slaughter houses, stables and sewers. The innovative grinder system allows to cut the solid parts and to pump them with the liquid, ensuring the cleaning of the tubing. All the material that for its dimentions cannot pass through the grinder is rejected from the grinder itself. 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 : 60°C - Intermittent duty : 90°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 materials of which the electropump is made are: G20 cast iron (motor cover, motor casing, pump body, impeller), stainless steel AISI 420 (motor shaft), stainless steel screws, while the gaskets are made of nitrile rubber (oil-resistant). The bearings are of high quality and need to be greased after a long period of operation. Upper mechanical seal made of ceramic/graphite and lower mechanical seal made of silicon-carbide. Grinder system made of hardned stainless steel.
