waterelectricsubmersible

Submersible electric pumps for 3” wells or larger. These units have a very extensive range of applications for lifting and distribution in civil and industrial water systems, filling of pressure vessels and tanks, pressurization and irrigation systems. APPLICATIONS High-speed electric borehole pumps for 3“ wells or larger. These units have a very extensive range of applications for lifting and distribution in domestic and industrial water systems, filling of pressure vessels and tanks, pressure booster and irrigation systems. CONSTRUCTION FEATURES OF THE PUMP Multi-stage centrifugal pump type. Pump and motor connected with rigid coupling. Noryl impellers and self-lubricating polyacetyl diffusers. Pump shell, shaft, coupling, filter and cableguard in stainless steel. Base support and delivery head in brass with incorporated non-return valve. CONSTRUCTION FEATURES OF THE MOTOR Asynchronous submersible two-pole motor, made of stainless steel AISI304 with brass supports. Squirrel cage rotor mounted on Kingsbury thrust bearing. Cooling of the thrust bearing kit and bushings is provided by water, this prevents any risk of contamination. Stainless steel canned stator, filled with thermosetting resin with high insulation property and better thermal dissipation capability.
