Pump selection guide: Best uses of pumps

1
Classification Of Pumps And Their Uses
2

• A pump is a device that transfers liquid from low
  head to high head and is used to increase the
  pressure of a liquid. The pump further is
  classified into two categories rotodynamic pump
  and positive displacement pump.

Classification of Pump

• Rotodynamic Pump
• ? Centrifugal pump
• ? Propeller pump
• Positive Displacement Pump
• ? Reciprocating pump
•            Piston pump
•             Plunger pump
•             Diaphragm pump
• ? Rotary
•  Gear pump
•  Vane pump
•  Lobe pump
• Screw pump
• There are 8 HP diesel engine water pumps, which
  have 8 HP (Horsepower) engine capacity.
  Horsepower is nothing but the unit used for
  output power or the rate at which it expends
  mechanical energy.

Rotodynamic pump

• Rotodynamic has two meanings roto means rotating
  component, and dynamic means a substance or a
  liquid has a high velocity. In Rotodynamic, the
  dynamic energy of the liquid is increased. The
  velocity of the liquid increases in Rotodynamic
  pumps. Further, the velocity is converted into
  pressure energy in another device.
• This Rotodynamic pump operates on the principle
  of the rise in liquid pressure energy by dynamic
  action (increasing its velocity) of liquid. This
  velocity of the liquid is increased in an
  impellerthe velocity of the liquid supplies into
  the casing. In the casing, velocity energy
  converts into pressure energy. 
• There are two types of pumps in a Rotodynamic
  pump which are centrifugal pump and propeller
  pump.

5
Centrifugal Pump

• As we all know, centrifugal force increases the
  velocity of a liquid in this pump due to the
  centrifugal action. In a centrifugal pump, the
  fluid transfers from one rotor to another by
  rotational energy, these rotors are called
  impellers. The life expectancy of centrifugal
  pumps is between 5 to 10 years. The centrifugal
  pump use to pump water, bases, acids, mild
  liquids, etc.
• Propeller pump
• Propeller pumps are designed in a way depending
  on conventional rotary impeller design. These
  pumps use significant flow volume rates in
  various applications, and it has moderate
  requirements of the head.

Positive Displacement Pump

• Positive displacement pumps operate on the
  definite quantity of liquid discharged or
  supplied from the pump. Due to the positive or
  actual displacement of the functional elements
  (like plunger, gear, piston, screws, vanes) are
  displaced or moved. This process is known as
  actual displacement. 
• Due to this, the actual displacement of the
  pressure of the liquid element increases
  directly. This process is known as the positive
  displacement pump. In positive displacement, we
  don't require to increase the velocity or further
  conversion. 
• Positive displacement pumps are further divided
  into two types - Reciprocating and Rotary pumps.

Reciprocating Pump

• Reciprocating is a type of motion in which
  elements like a piston or other device elements
  move to the cylinder's end flow. This process is
  known as Reciprocating. In a reciprocating pump,
  the piston moves up and down inside the cylinder.
  This movement is called reciprocating motion. 
• The reciprocating pump further divides into -
  piston pump, plunger pump, Diaphragm pump.
• Piston and Plunger pump
• Here the piston pump and plunger pump are
  similar the only difference is the plunger
  replaces the piston. The difference between
  piston and plunger is that piston pumps have a
  larger diameter and a small length, whereas the
  plunger pump has a higher length and a small
  diameter.
• Diaphragm pump
• A diaphragm pump has two ways for the liquids to
  discharge. It is a type of positive displacement
  pump that uses a mixture of the reciprocating
  action of thermoplastic, rubber, or Teflon.
• Rotary pump
• Another category in a positive displacement pump
  is a Rotary pump. The other pump elements, like
  gear, vanes, and lobes screws, are rotary
  components. The rotary pump further divides into
  four pumps depending on these components (Gear,
  vane, lobe, Screw) like Gear pump, Vane pump,
  Lobe pump, and Screw pump.

• Gear pump
• In a gear pump, two gears are used. With the help
  of these gears, the pressure of the liquid
  increases.  
• Vane pump 
• In this pump, the vanes move inside and outside
  the pump.
• Lobe pump
• The lobe rotates in a lobe pump. There are many
  types of lobe that have three lobes or four
  lobes, or even more. 
• Screw pump
• In a screw pump, with the help of screws, we
  increase the pressure level of the liquid.

Uses of Pumps

• ? Pump water from the bore Wells. 
• ? The energy industry uses Pumping gas, operating
  cooling towers, or pumping oil.
• ? Pond and aquarium filtering uses a Pump.
• ?  8 HP Diesel Engine Water Pumps Manufacture
  mainly create pumps used to lift mud and water
  efficiently.
• ? For liquid injection and water-cooling purposes
  in the Automobile industry, they use pumps.
• ? To recycle wastewater, paper, pulp, etc., in
  the chemical industry, they use pumps. 
• ? In wastewater treatment plants, to recycle
  wastewater, they use pumps.
• ? For dewatering sludge, the industry uses pumps.
• ? To measure chemical additives in liquids, the
  industry uses pumps.
• ? Pumps are used for mining and are widely spread
  in the usage of mineral applications. 
• ? Pumps have demand or increase demand
  significantly in paper industries because the
  production in the paper industry is
  non-stoppable.

Conclusion

• In this article, we have discussed the
  classification of pumps and their uses of pumps.
  We hope you have understood the basics of pump
  classification and the usage of pumps in various
  fields. Thus, the applications of pipes are
  widespread in many industries.
