Impeller Selection

-

 

  • The specific speed of centrifugal pump is defined as speed of geometrical Similar pump which would deliver one cubic meter of liquid per second against head of one meter

  • It is a function of shaft speed, flow rate, and differential head at the pump Best Efficiency Point 


Sp.Speed

  • It is a key consideration in the design and selection of pumps, and particularly pump impellers, is specific speed.

Parts of the Centrifugal Pump

-
Image
  Numerous components make up each centrifugal pump. Many centrifugal pumps share a few parts in common. These parts can be split into the mechanical end and the wet end. The wet end of the pump includes those parts that determine the hydraulic performance of the pump. The two primary parts of wet end are the impeller and casing . The components that hold the impeller within the casing are part of the mechanical end. The Pump shaft, Mechanical seals, Bearings, Bearing housing etc. are all part of the mechanical end of the device. Hydraulic & Mechanical assembly & CPK-Chemical Process Pump

Volute casing & Impeller

-
Image
  Volute of a centrifugal pump is the casing that receives the fluid being pumped by the impeller As liquid exits the impeller it has high kinetic energy and the volute directs this flow through to the discharge.  As the fluid travels along the volute it is joined by more and more fluid exiting the impeller but, as the cross sectional area of the volute increases, and velocity is gradually reduces. Volute casings come in three different types:  Single volute and Double volute The fundamental benefit of a double volute over a single volute is the equalization of the pressure distribution within the volute. Radial thrust can substantially increase the pump shaft deflection Pressure distribution comparison  for non diffuser volute casing The motional energy of one or more driven rotors, known as impellers, is transferred to power a centrifugal pump.  The fluid is...
