    CENTRIFUGAL PUMPS Introduction A centrifugal pump is a rotodynamic pump that uses a rotating impeller to create flow by the addition of energy to a fluid. Centrifugal pumps are commonly used to move liquids through piping. The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller‚ flowing radially outward into a diffuser or volute chamber (casing)‚ from where it exits into the downstream piping. Centrifugal pumps are used for

    CENTRIFUGAL PUMP A centrifugal pump converts the input power to kinetic energy in the liquid by accelerating the liquid by a revolving device - an impeller. The most common type is the volute pump. Fluid enters the pump through the eye of the impeller which rotates at high speed. The fluid is accelerated radially outward from the pump chasing. A vacuum is created at the impellers eye that continuously draws more fluid into the pump. The energy created by the pump is kinetic energy according the

    Submersible Pump Application The system consists of a submersible pump controlled by a Danfoss VLT AQUA Drive and a pressure transmitter. The transmitter gives a 4-20 mA feedback signal to the VLT AQUA Drive‚ which keeps a constant pressure by controlling the speed of the pump. To design a drive for a submersible pump application‚ there are a few important issues to take into consideration. Therefore the drive used must be chosen according to motor current. 1. The motor is a so called “Can motor”
