Pump - Definition, Types, Advantages and Disadvantages

WHAT IS THE PUMP?

• A Pump could be a device, which is used lifting a liquid from ground sources to upper top surfaces or from one place to a distinct place.

• Pumps are operate by the mechanism of rotary. Reciprocating and it consumes energy while performing mechanical work which is fluid moving one place to a unique place.

• This can be operated by many energy resources which include manual operation, electricity, engine, wind generation and lots of more, day to day life to industrial applications.

TYPES OF PUMPS:

A pump can broadly be classified into two categories, and those are:

1. Positive Displacement Pump
2. Dynamic pump

Also, there are two kinds of Positive Displacement Pump, and those are:

POSITIVE DISPLACEMENT PUMPS:

1) ROTARY PUMP:

• Single Rotor Pump (For example, Piston Pump, Vane Pump, Screw Pump)

• Multiple Rotor Pump (For example, Gear pump, Lube pump)

2) RECIPROCATING PUMP:

• Diaphragm Pump (For example, Fluid Operated Pump, Mechanically Operated Pump)
• Piston plunger type pump

And again Dynamic Pumps is can be classified into two types:

DYNAMIC PUMPS:

1. Centrifugal Pump
2. Axial Pump

RECIPROCATING PUMP:

• A reciprocating pump could be a hydraulic machine which converts the energy into hydraulic energy.

• Here a particular volume of liquid is collected within the enclosed volume and is discharged using pressure to the desired application.

• Reciprocating pumps are more suitable for low volumes of flow at high pressures.

The reciprocating pump having two types:

1. Single-acting reciprocating pump
2. Double-acting reciprocating pump

ADVANTAGES OF PUMPS:

These are some advantages of Pump:

• As there's  no drive seal so there isn't any leakage within the pump.

• There are very less frictional losses.

• The construction of the pump is straight forward.

• Almost no noise.

• Minimum wear as compared to others.

DISADVANTAGES OF PUMPS:

These are some disadvantages of Pump:

• Produce cavitation.

• Corrosion

• Cannot ready to work an high speed.

APPLICATIONS OF PUMPS:

The main applications of the pump are:

• As we already discussed Pumping Water from one place to a special place.

• Aquarium and pond filtering

• This is also used for Water cooling and fuel injection system in automobiles

• Pumping oil or gas and operating cooling towers within the energy industry.

• Uses in waste-water recycling, pulp, and paper, industry, etc.
