Diffusers

-

 

  • The diffuser is a part that, with the least amount of loss feasible, reduces flow velocity and raises static pressure in response.

  • A diffuser's distinguishing characteristic is a flow path with increasing cross-sectional area in the direction of flow, in a closed duct or channel

  • The vane angle for either volute or diffuser, if properly designed, is correct for only the capacity at the BEP. If the pump is operated at some other capacity, the diffuser may act as a hindrance rather than as an aid to efficient operation.

What is a Mechanical seal ?

-

We are all aware that the media used in pumps may be hazardous to humans, corrosive, valuable, etc., so it is very important to prevent leakage of the fluid. A Mechanical seal is a means to keep fluid confined in a vessel when a rotating shaft passes (Rotate) through a stationary housing or, very rarely, where the housing spins around the shaft. It is used to prevent media leaks, reduce friction between shaft and pump casing , boost efficiency , and guarantee the longevity of different pump parts. The design arrangement and materials of construction are essentially determined by the following factors:   Pressure Temperature Speed of the rotation  The product media One of the main causes of pump failure is mechanical seal failure. It is one of the most crucial parts of any hydraulic machine. The image and video that follows shows a pump with a failed mechanical seal.

  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.
