An Overview:

An Overview Pumps Types of Pumps Classification of pump Centrifugal pumps Characteristics of Centrifugal pump Working Mechanism of Centrifugal pumps Advantages & disadvantages of Centrifugal Pump Positive Displacement Pump Positive Displacement Rotary Pumps Positive Displacement Reciprocating pumps Applications of Pumps

What is a Pump:

What is a Pump A pump is a device used to move fluids, such as gases , liquids or slurries . Enhancing the fluid velocity , pressure and flow rate by giving mechanical energy A small, electrically powered pump

Energy required by pumps:

Energy required by pumps It depends upon : The height through which fluid is to be raised Pressure required at delivery point Length and diameter of pipe Flow rate Physical properties Viscosity & density

Types of Pumps:

Types of Pumps On the basis of Flow/capacity Type of the fluid Power consumption & many other such factors we divide pumps into these categories:- Dynamic Pumps Centrifugal Special effect pumps Displacement Pumps Rotary Reciprocating

Classification of pumps(Dynamic):

Classification of pumps(Dynamic)

Classification of pumps(Displacement):

Classification of pumps(Displacement)

The centrifugal pump:

The centrifugal pump “A centrifugal pump is a rotating machine in which flow and pressure are generated dynamically”. Very simple design Two main parts are the impeller and the diffuser Impellers Bronze poly carbonate cast iron stainless steel

Pressure developed by the Pump depends upon::

Pressure developed by the Pump depends upon: Impeller diameter No . of impellers size of the impeller eye shaft speed Size of the pump depends upon: Head Capacity

Working Mechanism of a Centrifugal Pump:

Working Mechanism of a Centrifugal Pump In its process It convert energy of a prime mover (a electric motor or turbine) first into velocity or kinetic energy and then into pressure energy of a fluid that is being pumped. The energy changes occur by virtue of two main parts of the pump, the impeller and the volute or diffuser. The impeller is the rotating part that converts driver energy into the kinetic energy. The volute or diffuser is the stationary part that converts the kinetic energy into pressure energy .

Advantages & Disadvantages of centrifugal Pump:

Advantages & Disadvantages of centrifugal Pump Advantages: Very efficient Produce smooth and even flow Reliable with good service life Disadvantages Loss of priming easily Efficiency depends upon operating design head & speed.

Positive-Displacement Pumps:

Positive-Displacement Pumps In Positive displacement pump ,the volume delivered is directly proportional to the displacement of piston. The pressure has no effect on the volume. More the speed , more will be the displacement of piston and more will be the volume .

Positive displacement rotary pumps:

Positive displacement rotary pumps Positive displacement rotary pumps move fluid using a rotating mechanism that creates a vacuum that captures and draws in the liquid Advantages: Rotary pumps are very efficient because they naturally remove air from the lines, eliminating the need to bleed the air from the lines manually . Screw pump

Reciprocating positive displacement pumps:

Reciprocating positive displacement pumps Reciprocating pumps move the fluid using one or more oscillating pistons, plungers, or membranes (diaphragms), while valves restrict fluid motion to the desired direction A plunger pump compared to a piston pump

CHOICE OF PUMPS:

CHOICE OF PUMPS Choice of pumps depend upon the following factors:- The quantity of the liquid to be handled. The head against which the liquid is to be pumped. The nature of the liquid to be pumped. The nature of the power supply.

Applications of Pumps :

Applications of Pumps DAILY LIFE APPLICATINS:- Pumps are used throughout society for a variety of purposes . Today , the pump is used for irrigation water supply gasoline supply air conditioning systems refrigeration (usually called a compressor ) sewage movement flood control etc.
