how industrial liquid handle ? i just try to mention. if you like my job then i am satisfied.

1. LIQUID HANDLING
DIFFERRENT TYPES OF PUMPS
PRESENTED BY GROUP B

2. Liquid Handling Pumps
.

3. • 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

4. 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

5. Use of centrifugal pumps :
They are generally used where high flow rates
and moderate head increases are required.

9. Piston Pump

10. Plunger Pump

12. 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.
