Centrifugal pump

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.

  • How does Centrifugal pump work ? (video 4:37) – animated video explains the working of centrifugal pumps. Importance of priming, cavitation and commonly used impeller types are illustrated in this video. They are common home water pumps. Mechanical design aspects of centrifugal pump such as water sealing arrangement and bearing housing are also well explained here.
  • Centrifugal pump (video 5:54) – Working of Centrifugal pump is explained in this video lecture. Here working of a semi open, single suction centrifugal pump is described in a detailed way. Construction details of volute casing and turbo machinery analysis of impeller, difference between backward curved, radial, forward curved blade impellers are described in this lecture.

That’s engineering

  • pressure – how much something is pushing on something else. It is expressed as force per unit area: P=F/A
