LIQUID HANDLINGDIFFERRENT TYPES OF PUMPS

PRESENTED BY GROUP B

Liquid Handling Pumps

.

• Dynamic pumps, also called kinetic pumps. In dynamic pumps, energy is added to the fluid continuously through the rotary motion of the blades.This increase in energy is converted to a gain in pressure energy when the liquid is allowed to pass through an increased area.

 • Centrifugal pumps

CENTRIFUGAL PUMP

Used in liquid pumping.A centrifugal pump converts mechanical energy from a

motor to the of moving fluid. A portion of energy goes into kinetic energy of the fluid motion & some into potential energy, represented by fluid pressure or lifting the fluid,

against gravity, to a higher altitude

Use of centrifugal pumps :

They are generally used where high flow rates and moderate head increases are required.

Piston Pump

Plunger Pump

Screw Pumps

Screw pumps are rotary, positive displacement pumps that can have one or more screws to transfer high or low viscosity fluids along an axis. A classic example of screw pumps is the Archimedes screw pump that is still used in irrigation and agricultural applications. Although progressive cavity pumps can be referred to as a single screw pumps, typically screw pumps have two or more intermeshing screws rotating axially clockwise or counterclockwise. Each screw thread is matched to carry a specific volume of fluid.
