Single-stage centrifugal pump in block design Edur NNUBXS 80-160 G170V

Single-stage centrifugal pump in block design  is used to pump incompressible media that are available in fluid form and may include gaseous or solid contents. Centrifugal pumps transfer energy from the pump to the pumped fluid through fluidic processes. By means of an energy gradient, the pumped fluid flows via the suction nozzle into the pump, where it encounters the rotating impeller. The impeller is driven by the motor. The motor can drive the impeller directly via a shaft or via a stub shaft or a rigid flange coupling. The vanes of the impeller apply force onto the pumped fluid and increase its angular momentum. Energy is transferred to the pumped fluid and the pressure and absolute velocity increase. The energy content that is present in kinetic form in the increased absolute velocity is transformed into additional static pressure energy by means of a diffuser element. Guide vanes are used as the diffuser element. Together, the impeller and diffuser element are referred to as the pump's hydraulic system. To maintain the flow, an energy gradient must also be present at the pressure nozzle. Losses in the system caused by friction or leakages increase the pump's power consumption. The shaft seal prevents the pumped fluid from escaping at the rotating shaft. The vent screws are used to release trapped air. Motor 1,5 kW - 400 V - 50 Hz - 1.445 rpm - 3,15 A.
