Principles and Workings of The Pump

1. Centrifugal pumps

How it works Pumps Centrifugal pumps are transferring energy to the leaves / fan pump with basic deflection / modifier stream (fluid dynamics). Capacity generated by the centrifugal pump is proportional to the rotation, while the total head (pressure) is generated by the centrifugal pump is proportional to the square of the speed of rotation.

2. Positive Displacement Pumps

The nature of the pump is pressed periodic changes in the contents of the room separate from the suction and pressure which are separated by a section of the pump.

Capacity generated by the pump pressure is proportional to the speed of movement or the speed of rotation, while the total head (pressure) is generated by the pump is not dependent on the speed of movement or rotation. Pump urged to differentiate on: oscillating pumps and displacement rotary pumps.

  • Oscillating pumps : piston / plunger pump, diaphragm pumps.
  • Displacement rotary pumps : rotary pump, eccentric spiral pumps, gear pumps, vane pumps and others.

3. Jet pumps

For Jet pump is a plunger to remove fluid from a very deep place. Changes in the pressure of the nozzle caused by the flow of the medium used to bring the liquid up (ejector principle). The media used can be either liquid or gas. This pump has no moving parts and its construction is very simple. The effectiveness and efficiency of these pumps is very limited.

4. Air lift pumps

The workings of this pump is highly dependent on the action of a mixture of liquid and gas (two-phase flow)

5. Hydraulic pumps

This pump uses the kinetic energy of the pumped liquid in a column and the energy given that suddenly blow into another form of energy (energy-press).

6. Elevator Pump

The workings of this pump is lifted fluid to higher ground using a wheel, the Archimedes’ screw and similar equipment.

7.Electromagnetic Pumps

The workings of this pump is working directly dependent on a magnetic field on the ferromagnetic media streamed, therefore the use of these pumps is limited to the liquid metal.
